The various integrated features  20  and removable features  140  illustrated in  FIG.  2    are merely exemplary and not meant to be limiting. Any practicable integrated feature  20  or removable feature  140  may be included in the support apparatus  10  without departing from the teachings herein. 
     With reference now to  FIGS.  1 - 3   , integrated features  20  are activated via an input communicated to the control unit  22  without additional or detachable hardware being coupled to the bed  40 . In a non-limiting example, as illustrated in  FIG.  3   , the integrated feature  20  may be the pneumatic system  130  within an interior of the mattress  14 . The pneumatic system  130  includes bladders  170  positioned in the mattress  14  and in fluid communication with the pump  132  for adjusting fluid within the bladders  170 . The amount of fluid within each bladder  170  adjusts the firmness of the mattress  14 . Additionally, the bladders  170  may be used for various therapies and treatments, such as, pressure ulcer prevention. The bladders  170  may be adjusted in a certain pattern to apply pressure therapy or other treatments to the patient and the support apparatus  10 . The pneumatic system  130  may be disposed within the mattress  14  and activated without additional hardware or features being connected to the mattress  14  or the support apparatus  10 , thereby being integrated into the mattress  14  and controlled via the software and/or changes in the software configuration. 
     In various examples, the mattress  14  includes an upper cover  172  and a base cover  174  that enclose the pneumatic system  130 . The pneumatic system  130  may provide one or more types of treatment to the patient. For example, the pneumatic system  130  may be utilized to provide continuous lateral rotation therapy or a continuous lateral rotation feature for the patient on the support apparatus  10 . The bladders  170  may include rotation bladders  176  within the mattress  14 . The rotation bladders  176  may be deployed or inflated in a certain pattern to provide a gentle, side-to-side movement of the patient to aid in the prevention and treatment of pulmonary and other health complications related to immobility, as well as treat or prevent pressure ulcers. 
     In the illustrated configuration of  FIG.  3   , the rotation bladders  176  include first and second turn bladders  178 ,  180  arranged adjacent to third and fourth turn bladders  182 ,  184 . The first and second turn bladders  178 ,  180  are arranged under a torso of the patient when the patient is lying on the support apparatus  10  and operate to turn the torso along a longitudinal axis in response to the inflation of one of the first and second turn bladders  178 ,  180 . The third and fourth turn bladders  182 ,  184  are arranged under a seat or thigh of the patient and operate to turn the legs of the patient along the longitudinal axis in response to the inflation of one of the third and fourth turn bladders  182 ,  184 . For example, to rotate the patient to the right, the second and fourth turn bladders  180 ,  184  are inflated. The first and third turn bladders  178 ,  182  may remain in a current state or may deflate. As illustrated in the example of  FIG.  3   , the first and second turn bladders  178 ,  180  are in fluid communication with the third and fourth turn bladders  182 ,  184  for concurrent inflation and deflation. However, each set of rotation bladders  176  may operate independently. Additional rotation bladders  176  may be included in the pneumatic system  130  without debating from the teachings herein. 
     Referring still to  FIGS.  1 - 3   , the rotation bladders  176  operate to adjust the patient between a center position, in which the patient is lying on his or her back, and lateral positions, in which the patient is lying on his or her right or left side. The control unit  22  may control the pneumatic system  130  to vary a number of turns, a pause time in each position, a duration of the continuous lateral rotation therapy, etc. to provide customized treatment for the patient. The amount of pressure provided by each rotation bladder  176  may be based on a detected or input weight of the patient. Additionally or alternatively, the therapy may be initiated and adjusted via the user interface  18  (e.g., in response to a software configuration change). 
     The pneumatic system  130  may include support bladders  186  arranged over the rotation bladders  176 . The support bladders  186  support the patient lying on the mattress  14 . Each of the support bladders  186  may include one or more cells that may be concurrently or independently adjusted between inflated and deflated conditions. The support bladders  186  may also be utilized to provide alternating pressure therapy to the patient. When providing alternating pressure therapy, a first set of support bladders  188  are in fluid communication, and a second set of support bladders  190  are in fluid communication. 
     The first set of support bladders  188  and the second set of support bladders  190  are arranged in an alternating pattern. Accordingly, the first set of support bladders  188  and the second set of support bladders  190  are separately inflated, maintained, or deflated in a pattern to relieve pressure points by cyclically dropping or elevating a pressure within one of the first set of support bladders  188  and the second set of support bladders  190 . The control unit  22  may include alternating pressure therapy protocols that include at least frequency, duration, pattern, and intensity of the therapy. The alternating pressure therapy may be initiated and adjusted (e.g., frequency, duration, intensity, etc.) via the user interface  18  (e.g., in response to a software configuration change). 
     Additionally or alternatively, the pneumatic system  130  may be utilized to provide percussion and vibration therapies to the patient on the support apparatus  10 . The percussion and vibration therapies may be conducted separately or together as sequential treatments. Percussion and vibration therapy (PVT) bladders  192  are disposed over the support bladders  186 . While illustrated in  FIG.  3    proximate the head end of the mattress  14 , the PVT bladders  192  may be disposed in other locations in the mattress  14 , or alternatively, multiple sets of PVT bladders  192  may be disposed in the mattress  14 . The PVT bladders  192  provide percussion or vibration therapies when pressure in the PVT bladders  192  drops and elevates at a rate sufficient to impart a vibration to the patient. For example, percussion or vibration therapy may be applied to a chest region of the patient to aid in breaking down undesired materials within the lungs of the patient. 
     Referring still to  FIGS.  1 - 3   , the percussion and vibration therapies may also be utilized in conjunction with other therapies, such as continuous lateral rotation therapy. The control unit  22  may include percussion and vibration protocols that include at least the frequency, duration, and intensity of the therapies. The percussion and vibration therapies may be initiated and adjusted (e.g., frequency, duration, intensity, etc.) via the user interface  18 . The percussion and vibration therapies may be utilized to treat or prevent pulmonary or other complications associated with immobility, treat or prevent pressure ulcers, or any additional medical benefits. 
     The pneumatic system  130  may also be utilized for providing a turn assist for the caregiver. The control unit  22  may include a turn assist protocol, which assists the caregiver in turning the patient on the support apparatus  10  for linen changes, dressing changes, bed pan placement, back care, and other procedures or treatments. When the turn assist protocol is activated, some or all of the bladders  170  in the mattress  14  are adjusted. 
     For example, when the patient is to be turned onto his or her right side, the bladders  170  on the left side of the mattress  14  may inflate, consequently rotating the patient. In such an example, the bladders  170  on the right side of the mattress  14  may remain in a current state (e.g., neither inflate nor deflate) or may deflate to further contribute to the rotation of the patient. The turn assist protocol may be initiated through the user interface  18 . In various examples, certain conditions of the support apparatus  10  may be met before the turn assist protocol is initiated. For example, the siderails  62  in the direction the patient is to be turned may be raised before the turn assist protocol is initiated. In such configurations, an alert or message may be provided via the user interface  18  if the condition is not met prior to the attempted activation of the turn assist protocol. 
     The pneumatic system  130  may also include a fill bladder  194  disposed below the support bladders  186  within the mattress  14 . The fill bladder  194  may be utilized to fill a gap formed between the support bladders  186  and adjustable frame  44  as the adjustable upper frame  44  articulates between different positions. As different segments  52 ,  54 ,  56  of the adjustable frame  44  move, the fill bladder  194  inflates to fill any gap or space between adjacent segments  52 ,  54 ,  56 . It is contemplated that the pneumatic system  130  may have additional components or functions without departing from the teachings herein. It is also contemplated that the pneumatic system  130  may include fewer bladders  170  where each bladder  170  performs multiple functions to provide different therapies. 
     Additionally or alternatively, the mattress  14  generally includes a shell assembly  196  for retaining the various components of the pneumatic system  130  in a selected position. The shell assembly  196  includes at least first, second, and third shells  198 ,  200 ,  202  that retain the bladders  170  in selected regions (e.g., head end, seat, etc.) of the mattress  14 . The shell assembly  196  is disposed on the base cover  174  and provides support for the pneumatic system  130 . The shell assembly  196  may also assist in positioning or retaining the pump  132 . It is contemplated that tubing, manifolds, or other connectors may extend from the pump  132  and through the mattress  14  to connect with each of the bladders  170 . The shell assembly  196  may include grooves or other features for guiding the tubing between the pump  132  and the various bladders  170 . 
     With reference still to  FIGS.  1 - 3   , the pneumatic system  130  can be activated through the user interface  18 , which is typically coupled to one of the siderails  62 . Without any additional hardware to be connected to the support apparatus  10 , the input through the user interface  18  directly controls the pneumatic system  130 . Each integrated feature  20 , such as the exemplary integrated feature  20  of the pneumatic system  130 , is directly affected by the input received into the control unit  22 . 
     Referring again to  FIGS.  1  and  2   , as previously noted, one example of the integrated feature  20  includes the force sensors  102 , which are generally coupled to the upper frame  44 . The force sensors  102  are configured to sense a force or weight of the patient, as well as monitor a position of the patient. The force sensors  102  may be utilized to monitor movement of the patient on the support apparatus  10 . The force sensors  102  may be included in the scale feature  104  of the support apparatus  10 . The scale feature  104  is configured to weigh or monitor the weight of the patient disposed on the support apparatus  10 . 
     The force sensors  102  may additionally or alternatively be included in the bed exit feature  106  of the fall risk protocol. When the fall risk protocol is activated, the patient may not exit the support apparatus  10  unassisted due to the risk of a fall event occurring. The fall risk protocol is configured to alert a caregiver when the patient is attempting to exit the support apparatus  10 . The force sensors  102  sense the weight or the position of a center of gravity of the patient on the support apparatus  10 . Based on the sensed weight relative to an edge of the support apparatus  10 , the bed exit feature  106  is configured to alert the caregiver of the exit attempt. The bed exit feature  106  may also include the light  108  integrated into the frame  12 , which is activated to provide additional lighting around the support apparatus  10  to assist with standing from the support apparatus  10 . The light  108  may also convey information to the caregiver (e.g., by color, intensity, etc.). 
     With reference still to  FIGS.  1  and  2   , the integrated feature  20  may include the actuation assembly  58  for adjusting the segments  52 ,  54 ,  56  of the upper frame  44 . The patient or the caregiver can activate the actuation assembly  58  to adjust the upper frame  44  to a selected position for treatment or comfort. In certain aspects, the adjustment of the upper frame  44  may be limited by the caregiver. For example, based on the condition of the patient, the head of the patient should be elevated. In such examples, the head end segment  52  may be adjustable between various angles but may not be adjusted lower than a 30° angle relative to a flat position. The angle of the head end segment  52  may be advantageous for patients with head or respiratory conditions or for preventing respiratory conditions. 
     Additionally, the lift system  48  is another example of the integrated feature  20 . The lift system  48  is integrated into the frame  12  to adjust the upper frame  44  relative to the base frame  42 . The lift system  48  may be included in the stand assist system  100 , which positions the support apparatus  10  to assist the patient in moving from a sitting position to a standing position. For example, when the stand assist system  100  is activated, the lift system  48  lowers the upper frame  44  to allow the patient to place his or her feet on the underlying floor surface when sitting on the support apparatus  10 . It is contemplated the segments  52 ,  54 ,  56  of the upper frame  44  may also be adjusted for the stand assist system  100   
     Further, the integrated feature  20  may include the length adjustment system  112 . When the support apparatus  10  includes the length adjustment system  112 , the footboard  114  is adjustable between the deployed position and the retracted position to adjust the length of the upper frame  44 . The retraction assembly  116  adjusts the footboard  114 , allowing the support apparatus  10  to be customized to the height of the patient. Further, the position of the footboard  114  may assist in minimizing shear forces and patient migration toward a foot end  210  of the support apparatus  10 . Moreover, the position of the footboard  114  can assist in minimizing sliding when the support apparatus  10  is adjusted to the chair position. 
     With further reference to  FIGS.  1  and  2   , the integrated feature  20  may be an indicator system  120  of the support apparatus  10 . As illustrated in  FIG.  1   , the indicator system  120  is generally located at the foot end  210  of the support apparatus  10  adjacent to the footboard  114 . The indicator system  120  includes multiple indicator lights  122  and the projectors  124  associated with each indicator light  122 . The indicator system  120  is associated with the various integrated features  20  and removable features  140  of the support apparatus  10 . The indicator lights  122  may be illuminated when the corresponding integrated feature  20  or the corresponding removable feature  140  is activated. For the removable features  140 , the indicator lights  122  may also illuminate when the removable features  140  are coupled with the support apparatus  10 . 
     The indicator lights  122  may illuminate in different colors to indicate different information to the caregiver. For example, a green light may indicate that the corresponding feature  20 ,  140  is active, while a red light may indicate an alert related to the corresponding feature  20 ,  140 . The projectors  124  may project the images  126  on the underlying floor surface that is substantially similar (e.g., design, icon, colors, etc.) to the indicator light  122  to provide a secondary location for the caregiver to view the information. The indicator system  120  provides a convenient method for caregivers to monitor information about the support apparatus  10  or the patient. 
     In the example illustrated in  FIG.  1   , the indicator system  120  is associated with four different features, therefore having four indicator lights  122  and four projectors  124 . The exemplary features associated with the indicator system  120  include the bed exit feature  106 , the stand assist system  100 , the MCM system  142 , and the vital signs system  144 . The bed exit feature  106  and the stand assist system  100  are integrated features  20 , while the MCM system  142  and the vital signs system  144  are removable features  140 , as discussed further herein. 
     Referring still to  FIGS.  1  and  2   , as previously set forth, the removable features  140  are selectively and removably coupled to the support apparatus  10 . In comparison to the integrated features  20 , the removable features  140  include additional or detachable hardware that is coupled to the support apparatus  10 . In this way, the removable features  140  can be adjusted via an input into the user interface  18 ; however, if the additional hardware is not coupled to the support apparatus  10 , then no adjustment occurs. Accordingly, operation of the removable features  140  is restricted based on the hardware availability. The addition and removal of the hardware operate to prevent inadvertent or accidental activation of the removable features  140 . When coupled to the support apparatus  10 , the removable features  140  are in communication with the control unit  22 . In this way, the control unit  22  is configured to determine which removable features  140  are coupled to the support apparatus  10  at a given time. 
     The removable features  140  may be added for patient comfort, patient entertainment, treatment, therapy, etc. In a non-limiting example, the removable feature  140  may include the pendant  146 , which is coupled to the frame  12  and extends from a support rod to hang a housing in front of the patient. The housing may include a display screen for providing information, entertainment, controls, etc. to the patient. Additionally or alternatively, the pendant  146  may provide a location for the patient to position a personal device, such as a phone or tablet. The pendant  146  may include a connector port that allows the patient to couple the personal device to the pendant  146  to be charged. 
     Another example of the removable feature  140  may include the pillow speaker  148  or nurse call remote that may be selectively coupled to the support apparatus  10 . The pillow speaker  148  generally provides controls for various features in the patient room, such as television control, lighting control, etc., as well as a call feature allowing the patient to contact the caregiver. 
     Further, an additional non-limiting example of the removable feature  140  may be the incontinence detection system  150 . The incontinence detection system  150  generally includes sensors  152 , a pad  154 , and an indicator  156  (see  FIG.  18   ). When activated, the sensors  152  operably coupled with the pad  154  are configured to sense an incontinence event and the indicator  156  alerts the caregiver that such event has occurred. Further, the incontinence detection system  150  may include a blower. In such examples, the pad  154  includes a spacer material and the blower directs fluid, such as air, through the spacer material of the pad  154 . The air traveling through the pad  154  wicks moisture from the patient and assists in drying the skin of the patient. 
     Further, the removable features  140  may be the MCM system  142 . The MCM system  142  generally includes a blower, a top coverlet, and a spacer material within the top coverlet. The blower is controlled by the control unit  22  and operates to direct or blow air through the spacer material. The MCM system  142  is generally disposed on a top surface of the mattress  14  and the patient may rest on the MCM system  142  while the patient is positioned on the MCM system  142 , air is directed through the top coverlet. This configuration wicks away moisture from the skin of the patient by blowing air underneath the patient, which is advantageous for preventing skin conditions and which may be caused by lying on the mattress  14  for an extended period of time. 
     Referring still to  FIGS.  1  and  2   , the removable feature  140  may include the vital signs system  144 . The vital signs system  144  generally includes a sensor assembly positioned below the mattress  14  on the upper frame  44  in a position that aligns with a chest of the patient. The sensor assembly may be configured to sense a heart rate and a respiration rate of the patient. Each of these removable features  140  includes additional hardware to be coupled to the support apparatus  10 . 
     With reference now to  FIG.  4   , the user interface  18  is configured as the control panel  90  operably coupled to the support apparatus  10 , such as on the siderail  66  (as illustrated in  FIG.  1   ). The control panel  90  includes two pins  222 , which allow the control panel  90  to be rotatably coupled and rotate relative to the support apparatus  10 . The control panel  90  includes the graphical touchscreen display  92 , allowing the caregiver to view information and provide various inputs, which are communicated to the control unit  22  of the support apparatus  10 . 
     In the illustrated example of  FIG.  4   , the touchscreen display  92  includes a variety of information  226  and icons  228 . For example, the touchscreen display  92  includes a head angle measurement  230 , which conveys the angle of the head end segment  52  of the support apparatus  10  relative to the flat position. Further, the illustrated touchscreen display  92  includes an active alert  232  related to the bed exit feature  106 . This active alert  232  indicates to the caregiver that the bed exit feature  106  is activated and the caregiver will be alerted if the patient attempts to exit the support apparatus  10  unassisted. Additionally, vital signs information  234  including a heart rate  236  and a respiration rate  238  are included on the touchscreen display  92 . The vital signs information  234  is received from the vital signs system  144  when the sensor assembly is coupled to the support apparatus  10 . 
     The touchscreen display  92  also includes icons  228  that are selectable by the caregiver. The icons  228  generally relate to the integrated features  20  and the removable features  140 . The touchscreen display  92  may be dynamically or automatically updated based on the removable features  140  that are currently coupled with the support apparatus  10 . In the example illustrated in  FIG.  4   , for integrated features  20 , the touchscreen display  92  includes a head angle icon  250  related to adjusting the angle of the head end segment  52 , a sitting position icon  252  related to adjusting the upper frame  44  into the chair position, a stand assist icon  254  related to the stand assist system  100 , a pneumatic system icon  256  related to the pneumatic system  130 , and a length adjustment icon  258  related to the length adjustment system  112 . For removable features  140 , the touchscreen display  92  includes an MCM icon  260  related to the MCM system  142 . 
     Additionally, under a home icon  262 , which directs the caregiver to a home display screen, the touchscreen display  92  also includes icons  228  related to the integrated features  20 , such as a bed exit icon  264  related to the bed exit feature  106  and a scale icon  266  related to weighing the patient, and icons  228  related to the removable features  140 , such as a vital signs icon  268  related to the vital signs system  144 . Further, the touchscreen display  92  also includes a settings icon  270 , a help feature  272 , a service screen icon  274 , and a battery status  276 . Each of the icons  228  may be configured to activate, adjust, or deactivate (i.e., control) the corresponding feature or may adjust the touchscreen display  92  to a subsequent screen allowing the caregiver to control aspects of the related feature  20 ,  140 . The information  226  and icons  228  communicated via the touchscreen display  92  is merely exemplary and can include any practicable information useful to the caregiver. 
     As illustrated in  FIG.  4   , each of the icons  228  associated with the integrated features  20  includes a lock indicator  278  adjacent to the respective icon  228 . In comparison, the icons  228  associated with the removable features  140  do not have the lock indicator  278  associated with the respective icon  228 . The lock indicator  278  conveys that the features  20  associated with the icons  228  are in the locked state and utilize additional authorization to activate, adjust, deactivate, or otherwise control the feature  20 . The locked state is the default condition for the integrated features  20  to prevent unauthorized, inadvertent, or accidental operation of the integrated features  20 . 
     With reference now to  FIG.  5   , a service screen  290  on the control panel  90  is illustrated, which may be accessed by selecting the service screen icon  274  ( FIG.  4   ). The exemplary service screen  290  illustrated in  FIG.  5    includes controls for the pneumatic system  130 . The integrated features  20  are generally controlled through the service screen  290  or a service tool. The inputs entered through the service screen  290  are configured to adjust the software configuration within the control unit  22  to control the integrated features  20  accordingly. The integrated features  20 , which are not restricted by hardware availability, are controlled through the inputs provided to the control unit  22 . Accordingly, additional authorization or security may prevent inadvertent, unauthorized, or accidental control of the integrated features  20 . For example, without additional authorization, if the steps to activate certain integrated features  20  became known by those other than the caregiver, the integrated features  20  could be controlled in a manner that adversely affects the patient, the caregiver, or the facility. 
     Referring now to  FIGS.  4 - 6   , the integrated features  20  are controlled in accordance with the user input by being authorized through an authorization system  300 . The authorization system  300  is configured to utilize the key code  24  to adjust the selected integrated features  20  to the unlocked state to be controlled by the caregiver, the patient, or another user. The authorization system  300  provides an additional step between inputting a command related to control of the integrated features  20  and the actual control of the feature  20  to prevent unauthorized, inadvertent, or accidental activation. 
     The authorization system  300  provides an additional check in the control unit  22  for the features  20  that are controlled primarily or entirely through the change in software configuration. In comparison, the removable features  140  may not be authorized through the authorization system  300 . Inadvertent, accidental, or unauthorized activation is unlikely or prevented for the removable features  140  based on the hardware availability (e.g., being disconnected from the support apparatus  10 ). If the hardware for removable feature  140  is not connected, even if the icon on the control panel  90  is selected, the removable feature  140  is not activated. Therefore, accidental or unauthorized activation of the removable features  140  is less likely. However, the authorization system  300  may be utilized for authorizing adjustments or control of the removable features  140  without departing from the teachings herein. 
     The authorization system  300  includes the authorization source  26  having the key code  24 , which provides authorization to the support apparatus  10  to control the selected integrated feature  20 . The key code  24  may have a variety of configurations or the medical facility may use a variety of key codes  24 . For example, the key code  24  may be a generic code for the medical facility. In another example, the key code  24  may be a specific or unique code for each support apparatus  10 . In such examples, the key code  24  may include the serial number or other identification data of the support apparatus  10  in addition to other alphanumeric values. In an additional example, the key code  24  may also be a specific or unique code for the integrated feature  20 , which is common throughout the medical facility. In another non-limiting example, the key code  24  may be a specific or unique code for the integrated feature  20  for each support apparatus  10 . The authorization system  300  may become increasingly complex as more aspects utilize unique or specific codes. 
     Referring still to  FIG.  6   , the key code  24  may also be encrypted to provide an additional level of security to the authorization system  300 . The key code  24  is typically an alphanumeric combination. Additional features or programs may be utilized or included in the authorization system  300  to generate complex and/or encrypted key codes  24 . One such process to encrypt the key code  24  may include hashing, which prevents the reverse engineering of the key code  24 . 
     Referring again to  FIGS.  4  and  6   , the authorization system  300  can store the key code  24  in a variety of authorization sources  26 . For example, the authorization source  26  may be an authorization device  302 , such as a universal serial bus (USB) device. The key code  24  may be stored in a memory  304  of the authorization device  302 . The authorization device  302  may be selectively coupled to a connector port  306  of the control panel  90 , as illustrated in  FIG.  4   . When the authorization device  302  is coupled with the control panel  90 , the control unit  22  can seek and obtain the key code  24  or key codes  24  stored within the authorization device  302 . This may provide wired communication between authorization device  302  and the control unit  22  of the support apparatus  10 . 
     As illustrated in  FIG.  7   , the authorization device  302  may be coupled with a caregiver device  308 , such as a service tablet. The service tablet may be connected to the support apparatus  10  via a device port  310 , which may be a USB port, a micro-USB port, or another port for allowing data communication. The device port  310  may be the same or a different type of port compared to the connector port  306 . The caregiver may selectively couple the service tablet to a support apparatus  10  for a variety of reasons, such as controlling various features of the support apparatus  10 , running diagnostics, etc. The authorization device  302  may be coupled with the service tablet (i.e., via a connector port  312 ) and the control unit  22  may communicate with the authorization device  302  via the wired connection and the service tablet. 
     Additionally or alternatively, the support apparatus  10  may communicate directly and/or wirelessly with the caregiver device  308 . In such configurations, the service tablet may not have any wired connection to the support apparatus  10 . Further, the support apparatus  10  and the service tablet may communicate directly, without Internet, Wi-Fi, cellular data, etc. 
     The support apparatus  10  may also have a connector port  314 , for example on one of the siderails  62 , to directly receive the authorization device  302 . In this way, the caregiver may couple the authorization device  302  with the support apparatus  10  directly to provide the key code  24 . It is contemplated that the support apparatus  10  may be configured to obtain or retrieve the key code  24  whether directly or indirectly coupled with the authorization device  302 . 
     Referring again to  FIG.  6   , the control unit  22  includes the communication circuitry  86  configured for bidirectional wired and wireless communication. The support apparatus  10  is configured to communicate with a local server  320  via one or both of wired and wireless communication. The local server  320  includes a controller  322  having a processor  324 , a memory  326 , and other control circuitry. Instructions or routines  328  are stored within the memory  326  and executable by the processor  324 . The controller  322  includes communication circuitry  330  configured for bidirectional wired and wireless communication. The local server  320  may store the key code  24  or key codes  24  within the memory  326  thereof. 
     With reference to  FIGS.  6  and  8   , each support apparatus  10  may be associated with a network interface unit  340 . Multiple network interface units  340  may be provided in various locations around the medical facility. It is contemplated that each support apparatus  10  may communicate with any one or more of the network interface units  340  within the medical facility. Each support apparatus  10  and each network interface unit  340  is assigned a unique identification (ID) code, such as a serial number. The local server  320  may have software (e.g., routines  328 ) that operates to associate bed ID data of the support apparatus  10  with network interface units ID data of the network interface units  340  to locate where each support apparatus  10  is positioned in the medical facility. When the network interface unit  340  is directly coupled to Ethernet  342  via a port  344 , as illustrated in  FIG.  9   , the associated support apparatus  10  communicates the bed ID to the network interface unit  340 , which then communicates the bed ID and the network interface unit ID to Ethernet  342  through wired communication. 
     The control unit  22  may wirelessly communicate with the local server  320 , as well as a remote server  350  and/or a remote device  352  via a communication network  354 . The remote server  350  also includes a controller  356  having a processor  358 , a memory  360 , and other control circuitry. Instructions or routines  362  are stored within the memory  360  and executable by the processor  358 . The remote server  350  includes communication circuitry  364  configured for bidirectional wired and wireless communication. The remote server  350  may store the key code  24  or key codes  24  within the memory  360  thereof. 
     Referring still to  FIG.  6   , the communication network  354  may be part of a network of the medical facility. The network may include a combination of wired connections (e.g., Ethernet  342 ), as well as wireless connections, which may include the wireless communication network  354 . The communication network  354  may include a variety of electronic devices, which may be configured to communicate over various wired or wireless communication protocols. The communication network  354  may include a wireless router through which the remotely accessed devices may be in communication with one another, as well as the local server  320 . 
     The communication network  354  may be implemented via one or more direct or indirect nonhierarchical communication protocols, including but not limited to, Bluetooth®, Bluetooth® low energy (BLE), Thread, Ultra-Wideband, Z-wave, ZigBee, etc. Additionally, the communication network  354  may correspond to a centralized or hierarchal communication network  354  where one or more of the devices communicate via the wireless router (e.g., a communication routing controller). Accordingly, the communication network  354  may be implemented by a variety of communication protocols, including, but not limited to, global system for mobile communication (GSM), general packet radio services, code division multiple access, enhanced data GSM environment, fourth generation (4G) wireless, fifth generation (5G) wireless, Wi-Fi, world interoperability for wired microwave access (WiMAX), local area network, Ethernet  342 , etc. By flexibly implementing the communication network  354 , the various devices and servers may be in communication with one another directly via the wireless communication network  354  or a cellular data connection. 
     Each of the controllers  322 ,  356  and the control unit  22  disclosed herein may include various types of control circuitry, digital or analog, and may each include a processor, a microcontroller, an application specific integrated circuit (ASIC), or other circuitry configured to perform the various inputs or outputs, control, analysis, or other functions described herein. The memories described herein may be implemented in a variety of volatile and nonvolatile memory formats. Routines may include operating instructions to enable the various methods described herein. 
     Referring still to  FIG.  6   , as well as  FIGS.  9  and  10   , exemplary wireless communications of the support apparatus  10  to the local server  320  are illustrated. The monitoring system may receive information from the support apparatus  10  via the communication network  354  and through the local server  320 . In certain aspects, the support apparatus  10  is configured to communicate with a wireless access transceiver  370 , which is coupled to Ethernet  342  of the medical facility. The communication network  354  provides for bidirectional communication between the support apparatus  10  and the wireless access transceiver  370 . The wireless access transceiver  370  communicates bidirectionally with Ethernet  342  via a data link  372 . 
     As illustrated in  FIG.  9   , the support apparatus  10  may be associated with the network interface unit  340 . The local server  320 , or other aspects of the authorization system  300 , may include software (e.g., routines  328 ) that operate to associate the identification code of the support apparatus  10  with the network interface units  340  identification data to locate each support apparatus  10  within the medical facility. Each network interface unit  340  includes the port  344  for selectively coupling with Ethernet  342 . When the network interface unit  340  is coupled with Ethernet  342 , the network interface unit  340  communicates the identification data to the support apparatus  10 , which then wirelessly communicates the data for the support apparatus  10  and the network interface units  340  to the wireless access transceiver  370 . The wireless access transceiver  370  then communicates with the local server  320  via Ethernet  342 . 
     As illustrated in  FIG.  10   , the support apparatus  10  may be capable of communicating wirelessly via a wireless communication module  380 . The wireless communication module  380  generally communicates via an SPI link with circuitry of the associated support apparatus  10  (e.g., the communication circuitry  86 ) and via a wireless 802.11 link with wireless access points  382 . The wireless access points  382  are generally coupled to Ethernet switches  384  via 802.3 links. It is contemplated that the wireless communication modules  380  may communicate with the wireless access points  382  via any of the wireless protocols disclosed herein. Additionally or alternatively, the Ethernet switches  384  may generally communicate with Ethernet  342  via an 802.3 link. Ethernet  342  is also in communication with the local server  320 , allowing information and data to be communicated between the local server  320  and the support apparatus  10 . 
     With reference again to  FIG.  6   , the support apparatus  10  may also communicate with the remote device  352 . The remote device  352  may belong to the caregiver (e.g., the caregiver device  308 ), such as a phone, a tablet, a laptop, a wearable device, etc. The remote device  352  may be the same as or separate from the caregiver device  308 . In certain aspects, the remote device  352  may store the key code  24  in a memory thereof. Additionally or alternatively, the remote device  352  may be selectively coupled with the authorization device  302 . In such examples, the control unit  22  is configured to wirelessly communicate with the remote device  352  to receive the key code  24  from the memory or the authorization device  302 . The support apparatus  10  may communicate with the remote device  352  directly (e.g., without Internet, cellular data, etc.) or via the communication network  354 . 
     Referring to  FIGS.  6 - 10   , the control unit  22  is configured to seek the key code  24  in response to an input relating to one of the integrated features  20 . The control unit  22  is configured to determine whether the authorization device  302  is coupled to the support apparatus  10  directly or indirectly. The control unit  22  may additionally or alternatively be configured to wirelessly communicate with one or more of the local server  320 , the remote server  350 , and the remote device  352  to seek the key code  24 . The control unit  22  includes routines  84  to determine the order for seeking the key code  24  as well as for locating the key code  24 . For example, the control unit  22  includes routines  84  directed to finding the location of the key code  24  within the authorization device  302  or location within the remote server  350 , the local server  320 , or the remote device  352 . Generally, the key code  24  is stored in a predefined location, such that the control unit  22  is programmed to follow a predefined path to the predefined location to retrieve the key code  24 . 
     Referring now to  FIG.  11   , if the key code  24  is unable to be retrieved or found, the control unit  22  may generate and communicate an error message  390 , such as the error message  390  illustrated on the control panel  90  in  FIG.  11   . There may be a variety of reasons for the error message  390  to be displayed. For example, the authorization device  302  may not be coupled to the support apparatus  10  (i.e., the control unit  22  is free of direct or indirect communication with the authorization device  302 ). Further, the local server  320 , the remote server  350 , and/or the local server  320  may also not be in communication (i.e., free of communication with) the control unit  22 . Further, the key code  24  may not be stored in the local server  320 , the remote device  352 , or the remote server  350 . In such examples, the key code  24  may not have been generated to prevent activation of the integrated feature  20  or the key code  24  may be unavailable due to a corruption of the path or location of the key code  24 . The error message  390  may notify the caregiver of the inability of the control unit  22  to obtain the key code  24  and control the integrated feature  20 . 
     In certain aspects, the caregiver may determine which integrated features  20  may be activated based on the treatment or therapy to be provided and the key code  24  is generated for those integrated features  20 . Additionally or alternatively, the patient may select integrated features  20  for comfort or as an upgrade to his or her medical facility stay, and the key code  24  may be generated for those integrated features  20 . If neither the caregiver nor the patient has selected the integrated features  20 , the key code  24  may not be generated and the integrated features  20  remain in the locked state. The key code  24  or key codes  24  may be continuously generated and deleted to dynamically adjust the authorization system  300 . 
     Referring to  FIG.  12   , the control unit  22  may also be configured to generate an alert  392 , which is communicated to the caregiver, for example, via the remote device  352  as illustrated in  FIG.  12   . The alert  392  indicates to the caregiver that at least one of the integrated features  20  was attempted to be activated and the key code  24  was not found by the control unit  22 . This may be due to an unauthorized attempted activation or a problem with the key code  24 . The alert  392  may be any visual, haptic, or audible alert. Additionally, the alert  392  may be communicated to a variety of locations, such as the remote device  352 , the caregiver device  308 , a nurse call station, a facility status board, etc. 
     Referring now to  FIG.  13   , the control unit  22  includes at least one routine  84  for authorizing and activating features  20  of the support apparatus  10  using the authorization device  302 . In step  400 , the control unit  22  is configured to receive an input related to the feature  20 ,  140  on the support apparatus  10  to be controlled (e.g., activated, deactivated, adjusted, etc.). In decision step  402 , the control unit  22  is configured to determine whether the selected feature  20 ,  140  is the integrated feature  20  or the removable feature  140 . The control unit  22  is configured to determine whether the selected feature  20 ,  140  utilizes detachable or additional hardware that is selectively coupled to the support apparatus  10 . In decision step  402 , if the control unit  22  determines that new or additional hardware is utilized by the selected feature  140 , then the control unit  22  proceeds to decision step  404 . 
     In decision step  404 , the control unit  22  is configured to determine whether the hardware for the selected removable feature  140  is coupled to the support apparatus  10 . If the hardware is not coupled to the support apparatus  10 , the control unit  22  proceeds to step  406  where the selected removable feature  140  is not activated or adjusted. In such configurations, even though the removable feature  140  was selected, the support apparatus  10  remains in a same condition. Returning to decision step  404 , if the detachable hardware is currently coupled to the support apparatus  10  and, consequently, in communication with the control unit  22 , the control unit  22  proceeds to step  408  of controlling the selected removable feature  140  in accordance with the input. 
     Returning to decision step  402 , if the selected feature is the integrated feature  20  and, therefore, does not utilize new or additional hardware, the control unit  22  proceeds to decision step  410 . In decision step  410 , the control unit  22  is configured to determine whether the authorization device  302  is connected. The authorization device  302  may be connected directly to the support apparatus  10 , to the control panel  90 , or to the caregiver device  308 . 
     If the authorization device  302  is connected, either directly or indirectly to the support apparatus  10 , the control unit  22  proceeds to step  412  to obtain or retrieve the key code  24  from the authorization device  302 . It is also contemplated that the control unit  22  may seek the key code  24  from the memory of the local server  320  via wired communication as described herein. The control unit  22  is configured to seek the key code  24  in a predefined location on a predefined path within the authorization device  302 . In step  412 , the control unit  22  is configured to adjust the selected integrated feature  20  to the unlocked state upon obtaining the key code  24 . After obtaining the key code  24 , the control unit  22  proceeds to step  414  where the selected integrated feature  20  is controlled in accordance with the user input. The control unit  22  may then return the integrated feature  20  to the locked state. The integrated feature  20  may be locked after a predefined period of time from the initial user input, from any user input, in response to an input to re-lock the feature  20 , etc. 
     Referring still to  FIG.  13   , returning to decision step  410 , if the authorization device  302  is not detected and the control unit  22  cannot obtain the key code  24  from the local server  320 , the control unit  22  proceeds to step  416  where the feature is not controlled. In this way, the integrated feature  20  remains in the current state of operation and in the locked state. The current state of operation may be an off or deactivated state. Alternatively, the current state of operation may be an activated state providing a certain function. For example, the pneumatic system  130  may be providing a select therapy and the select therapy continues without the key code  24  providing for authorization to adjust or deactivate the pneumatic system  130 . 
     In step  418 , the control unit  22  proceeds to generate and communicate (e.g., display) the error message  390 . The error message  390  may be displayed or otherwise communicated via the control panel  90 , the caregiver device  308 , the remote device  352 , or any other device of the medical facility. In step  420 , the control unit  22  is configured to generate and communicate the alert  392 . The alert  392  is generally communicated to the caregiver via the remote device  352  but may also be communicated via the control panel  90 , another facility device, etc. to indicate to the caregiver that there was an attempt to control the integrated feature  20  though the key code  24  was not obtained. The alert  392  may be generic, indicating that any adjustment to any integrated feature  20  was attempted, or specific, indicating that adjustment of the select integrated feature  20  was attempted. The alert  392  may also be adjusted to be personalized for the caregiver, the patient, or the facility. 
     It is contemplated that the key code  24  may also be utilized with the removable feature  140  when the detachable hardware is coupled to the support apparatus  10 . This configuration may be advantageous for providing an additional security check to prevent unauthorized control of the removable feature  140  when the detachable hardware is coupled to the support apparatus  10 . In such examples, when the control unit  22  determines in decision step  404  that the detachable hardware is coupled to the support apparatus  10 , the control unit  22  proceeds to decision step  410  to determine whether the authorization device  302  is connected. If so, the control unit  22  proceeds to step  412  to retrieve the key code  24  and then to step  408  to activate the removable feature  140 , or, if not, the control unit  22  proceeds to step  406  of not controlling the removable feature  140 . 
     Referring to  FIG.  14   , additionally or alternatively, the control unit  22  may include at least one routine  84  directed to authorizing and controlling features of the support apparatus  10  through wirelessly obtaining the key code  24 . In step  430 , the control unit  22  is configured to receive the input relating to the feature  20 ,  140  to be controlled. The control unit  22  then proceeds to decision step  432  to determine whether the selected feature  20 ,  140  utilizes new or additional hardware. If the control unit  22  determines that the selected feature  140  utilizes new or additional hardware, the control unit  22  proceeds to decision step  434 . 
     In decision step  434 , the control unit  22  is configured to determine whether the hardware is coupled to the support apparatus  10 . If the hardware is not coupled to the support apparatus  10 , the control unit  22  proceeds to step  436  where the selected removable feature  140  is not activated or adjusted. Returning to decision step  438 , if the hardware is coupled to the support apparatus  10 , the removable feature  140  is controlled based on the user input. 
     Referring still to  FIG.  14   , returning to decision step  432 , if the control unit  22  determines that the selected feature  20  utilizes no additional hardware and is, therefore, the integrated feature  20 , in step  440 , the control unit  22  is configured to seek the key code  24  via the communication network  354 . The control unit  22  is communicatively coupled with at least one of the remote server  350 , the local server  320 , and the remote device  352 . Based on the routine  84 , the control unit  22  follows the predefined path to the predefined location where the key code  24  is stored. For example, the predefined location may be the remote server  350 . In such examples, the control unit  22  may not seek the key code  24  from the local server  320  or the remote device  352 . Alternatively, the control unit  22  may seek the key code  24  from one or more of the remote server  350 , the local server  320 , and the remote device  352 . This may be advantageous if the predefined path to one location of the key code  24  is corrupted, and a secondary path can be utilized to authorize the use of the integrated feature  20 . 
     Upon locating the key code  24 , in step  444 , the control unit  22  is configured to retrieve or read the key code  24 . In step  444 , the control unit  22  is configured to adjust the selected integrated feature  20  to the unlocked state upon obtaining the key code  24 . In step  446 , the control unit  22  proceeds to control the selected integrated feature  20  in accordance with the user input. In step  446 , the control unit  22  may return the integrated feature  20  to the locked state. 
     Returning to decision step  442 , if the control unit  22  does not or cannot obtain the key code  24 , the control unit  22  proceeds to step  448 . The key code  24  may be unobtainable due to a lack of communication between the control unit  22  and the authorization source  26 , the key code  24  not being generated (e.g., no authorization), or an issue with the key code  24  or path to the key code  24 . In step  448 , the integrated feature  20  is not activated, adjusted, or deactivated as the input is not authorized. In step  450 , the control unit  22  is configured to generate and communicate the error message  390 , and in step  452 , the control unit  22  is configured to generate and communicate the alert  392 . 
     It is contemplated that the key code  24  may also be utilized with the removable feature  140  when the detachable hardware is coupled to the support apparatus  10 . In such examples, when the control unit  22  determines in decision step  434  that the detachable hardware is coupled to the support apparatus  10 , the control unit  22  proceeds to step  440  to seek the key code  24  and decision step  442  to determine whether the key code  24  is stored in a select location. If so, the control unit  22  proceeds to step  444  to retrieve the key code  24  and then to step  438  to activate the removable feature  140  or, if not, the control unit  22  proceeds to step  436  of not controlling the removable feature  140 . 
     Referring now to  FIG.  15   , additionally or alternatively, the control unit  22  may include at least one routine  84  configured to control features of the support apparatus  10  through wired and wireless communication with the authorization source  26 . In step  460 , the control unit  22  is configured to receive the input relating to the feature  20 ,  140  of the support apparatus  10  to be controlled. In decision step  462 , the control unit  22  is configured to determine whether or not the selected feature utilizes new or additional hardware (e.g., whether the selected feature is the removable feature  140  or the integrated feature  20 ). If the selected feature utilizes new or additional hardware, the control unit  22  proceeds to decision step  464  where the control unit  22  determines whether the hardware is coupled to the support apparatus  10 . If the hardware is not coupled to the support apparatus  10 , the control unit  22  proceeds to step  466  where the selected removable feature  140  is not activated or adjusted. In decision step  464 , if the hardware is coupled to the support apparatus  10 , the control unit  22  proceeds to step  468  to control the selected removable feature  140  in response to the received input. 
     Returning to decision step  462 , if the selected feature does not utilize new or additional hardware (e.g., is the integrated feature  20 ), the control unit  22  proceeds to decision step  470 . In decision step  470 , the control unit  22  is configured to determine whether there is wired communication with the authorization source  26 . Generally, in decision step  470 , the control unit  22  is configured to determine whether the authorization device  302  is connected to the support apparatus  10  either directly or indirectly. The control unit  22  may also seek the key code  24  from the local server  320  via wired communication. The control unit  22  is configured to follow the predefined path to the location of the key code  24 . Accordingly, the control unit  22  may seek the key code  24  in a single location or, alternatively, may seek the key code  24  in multiple locations. Seeking the key code  24  in multiple locations may be advantageous if there is an issue with a primary path and the key code  24  in a secondary location may grant authorization. 
     In decision step  470 , if the authorization device  302  is in communication with the control unit  22  by being coupled to the support apparatus  10 , the control unit  22  proceeds to step  472  to retrieve or read the key code  24 . In step  474 , the control unit  22  is configured to activate, adjust, or deactivate the integrated feature  20  in accordance with the user input. 
     Returning to decision step  470 , if the control unit  22  determines that the authorization device  302  is not connected to the support apparatus  10  or cannot otherwise obtain the key code  24  via the connected authorization device  302  (e.g., no key code  24  in the predefined location, an issue with the path, etc.), the control unit  22  proceeds to decision step  476 . In decision step  476 , the control unit  22  is configured to determine whether the key code  24  can be found in the authorization source  26  wirelessly. The control unit  22  is configured to wirelessly seek the key code  24  from one or more of the remote server  350 , the local server  320 , and the remote device  352  to seek the key code  24  and determine whether the key code  24  is available. The control unit  22  may follow the predefined path to the location of the key code  24  and may also follow a secondary path or a tertiary path to seek each location the key code  24  could be stored. 
     If the control unit  22  is able to locate the key code  24 , in step  478 , the control unit  22  is configured to retrieve or read the key code  24  and unlock the integrated feature  20 . In step  480 , the selected integrated feature  20  is controlled in accordance with the user input. After controlling the integrated feature  20  based on the user input, the integrated feature  20  may again be locked. 
     Returning to decision step  476 , if the key code  24  is not stored in the predefined location, the control unit  22  proceeds to step  482  where the integrated feature  20  is not activated, adjusted, or deactivated. Accordingly, the selected integrated feature  20  remains in the current state of operation and remains locked. The control unit  22  then proceeds, in step  484 , to generate and communicate the error message  390  and, in step  486 , generate and communicate the alert  392 . 
     The key code  24  may also be utilized with the removable feature  140  when the detachable hardware is coupled to the support apparatus  10 . The control unit  22  may seek the key code  24  before activating the removable feature  140  or prevent control of the removable feature  140  if the key code  24  is not obtained. It is understood that the steps of the routines  84  set forth in  FIGS.  13 - 15    may be performed in any order, simultaneously, repeated, and/or omitted without departing the teachings provided herein. Further, each routine  84  described herein may be performed in combination or independently. 
     With reference now to  FIG.  16   , as well as  FIGS.  1 - 15   , a method  500  of controlling the integrated feature  20  includes step  502  of generating the key code  24 . The caregiver may input information into the authorization system  300  relating to which integrated features  20  are to be utilized. The integrated features  20  may be requested by the patient, included in an upgrade, or utilized by the caregiver for treating the patient. The information may be input via the remote device  352 , the caregiver device  308 , or another facility device. At least one of the remote server  350 , the local server  320 , and the remote device  352  includes software (e.g., routines) that generates the key code  24 . For example, the caregiver may input the information through the remote device  352 , which is communicated to the remote server  350  via the communication network  354 . The remote server  350  is then configured to generate the key code  24 . In another non-limiting example, the caregiver may enter the information through the caregiver device  308 , which is communicated to the local server  320 . 
     The generated key code  24  may be a more generic code, which is applicable for more than one caregiver, integrated feature  20 , or support apparatus  10 . The same key code  24  may be used to authorize multiple integrated features  20  or support apparatuses  10 . Alternatively, the generated key code  24  may be a more specific code that is utilized for a single support apparatus  10 , a single integrated feature  20 , etc. In such examples, the serial number of the support apparatus  10  may be included in the key code  24 , differentiating the key code  24  for each support apparatus  10 . 
     Further, in step  502 , the key code  24  may also be encrypted. For example, the key code  24  may be encrypted via hashing. By encrypting the key code  24 , the key code  24  may not be reverse-engineered. This provides additional protection to the authorization system  300 . 
     In step  504 , the key code  24  is stored in the authorization source  26 . The key code  24  may be downloaded and stored on the authorization device  302 . Additionally or alternatively, the key code  24  may be communicated via the communication network  354  to the local server  320 , the remote server  350 , or the remote device  352 . The predefined location for storing the key code  24  may be determined by the software that generates the key code  24  for the caregiver. In certain aspects, the predefined location and path may be programmed into the control unit  22 . 
     Additionally or alternatively, the software that generates the key code  24  may communicate the path and the location of the key code  24  to the control unit  22 . In such configurations, the information is stored in the control unit  22  and the routine  84  follows the path to the location. The control unit  22  may have routines  84  for following additional paths should the communicated or programmed path (e.g., a primary path) not lead to the key code  24 . Additionally or alternatively still, the software that generates the key code  24  may communicate the path and location for the key code  24  to a central location. The control unit  22  may be configured to seek the path and location information in the central location and be configured to determine which path and location correspond to the specific support apparatus  10  or integrated feature  20 . 
     In step  506 , the authorization source  26  is coupled with the support apparatus  10 . In certain aspects, the authorization device  302  is physically coupled, either directly or indirectly, to the support apparatus  10 . Additionally or alternatively, the support apparatus  10  is communicatively coupled with the authorization source  26  to be able to wirelessly communicate to retrieve the key code  24 . 
     In step  508 , the user input related to the integrated feature  20  to be controlled (e.g., activated, adjusted, or deactivated) is provided through the user interface  18 . The user interface  18  may be the control panel  90 , the remote device  352 , or another facility device. The user input is communicated to the control unit  22 . At this time, the integrated feature  20  is generally in the locked state, such that authorization is sought before any adjustment to the integrated feature  20  is made. In step  510 , the control unit  22  is configured to seek the key code  24  according to one or more of the routines  84  described herein. 
     In step  512 , the control unit  22  is configured to retrieve, obtain, read, or otherwise seek the key code  24  from the authorization source  26  as described herein. Additionally, in step  512 , the control unit  22  is configured to adjust the integrated feature  20  to the unlocked state. In step  514 , the control unit  22  is configured to control the integrated feature  20  in accordance with the user input. For example, if the integrated feature  20  is in the off state, the control unit  22  may be configured to activate the integrated feature  20 . If the integrated feature  20  is activated, the control unit  22  may be configured to deactivate the integrated feature  20 . Further, the control unit  22  may also be configured to adjust the integrated feature  20  (e.g., provide a different therapy, etc.). 
     In step  516 , the control unit  22  is configured to return the integrated feature  20  to the locked state, which is the default condition. The integrated feature  20  may be adjusted to the locked state after a predefined period of time has elapsed since the user input related to the integrated feature  20 , or any user input, was communicated to the control unit  22 . Depending on the integrated feature  20 , the integrated feature  20  may be deactivated in the locked state or may be maintained in the activated state. For example, the lift system  48  may be deactivated when in the locked state to maintain the upper frame  44  in the selected position. In another example, the pneumatic system  130  may remain activated when in the locked state to continue to provide the selected therapy. The integrated feature  20  may remain in the locked state until the authorization is again sought and provided. It is understood that the steps of the method  500  may be performed in any order, simultaneously, repeated, and/or omitted without departing from the teachings provided herein. 
     Referring to  FIG.  17   , as well as  FIGS.  1 - 16   , a method  530  for controlling the integrated feature  20  includes step  532  of providing the user input related to the integrated feature  20  to be controlled. Similar to method  500  illustrated in  FIG.  16   , in step  532 , the user input is generally provided via the control panel  90 , remote device  352 , etc. and is communicated to the control unit  22 . 
     In step  534 , the control unit  22  is configured to seek the key code  24  from the authorization source  26 . The control unit  22  may be configured to seek the key code  24  through wired communication with the authorization source  26 , through wireless communication with the authorization source  26 , or a combination thereof. In method  530 , the key code  24  is not obtained by the control unit  22 . For example, the caregiver may not have input information into the authorization system  300  for the key code  24  to be generated. In another example, the control unit  22  is free of communication with the authorization source  26 . The control unit  22  will not be able to obtain the key code  24  to provide authorization for the user input. 
     In step  536 , the control unit  22  is configured to generate the error message  390  in response to not finding or retrieving the key code  24 . In such configurations, the authorization device  302  may not be coupled to the support apparatus  10 , the key code  24  may not have been generated, the key code  24  may have been saved in an incorrect location, etc. The error message  390  is communicated to the caregiver, for example, via the touchscreen display  92  on the control unit  22 , the remote device  352 , a status board at a nurse call station, etc. 
     In step  538 , the control unit  22  is configured to generate the alert  392  and communicate the alert  392  to the caregiver. The alert  392  may be communicated to the remote device  352 , a nurse call station device, etc. The alert  392  notifies the caregiver that an unauthorized attempt at controlling the integrated feature  20  was made, an error occurred in the control unit  22  obtaining the key code  24 , etc. The control unit  22  is configured to maintain the selected integrated feature  20  in the current state or condition. In this method  530 , the authorization is sought, whether on purpose or accidentally, and is not provided by the authorization system  300 . It is understood that the steps of the method may be performed in any order, simultaneously, repeated, repeated, and/or omitted without departing from the teachings provided herein. 
     With reference to  FIGS.  1 - 17   , the authorization system  300  may be utilized with the support apparatus  10  as well as any other devices or assemblies that have integrated features  20 . The support apparatus  10 , and other devices, are often modular products that are flexible and scalable, providing multiple configurations with different integrated features  20 . The support apparatus  10  can be changed to include or remove various integrated features  20  and removable features  140 . The authorization system  300  provides additional steps to protect against unauthorized, accidental, or inadvertent control of the integrated features  20  included in the support apparatus  10 . 
     In certain aspects, the support apparatus  10  may be configured to transfer between different units of the medical facility. For example, it may be advantageous for the support apparatus  10  to be transferable or interchangeable between the intensive care unit (ICU) and a medical/surgical (MedSurg) unit. Typically, each of the MedSurg unit and the ICU utilize separate beds  40  having separate functions. However, the transferable or interchangeable support apparatuses  10  may be advantageous for providing a surge solution in medical facilities. For example, during certain surge events, surge patients may overflow from the ICU to the MedSurg unit. The surge patients may be provided the same care and treatments in ICU and the MedSurg unit using the support apparatus  10  disclosed herein. Further, the authorization system  300  may allow the same support apparatuses  10  to transfer between the ICU and the MedSurg unit with different features and functions being authorized depending on the current until in which the support apparatuses  10  are being used. 
     Referring to  FIG.  18   , the support apparatus  10  that is usable in both the MedSurg unit and the ICU provides a continuous lateral rotation (CLR) function for providing pulmonary treatment. The CLR function provides continuous side-to-side movement or rotation for the patient to address pulmonary concerns. The CLR function generally utilizes the pneumatic system  130  within the mattress  14 . Accordingly, the CLR function is an exemplary integrated feature  20  of the mattress  14 , which may be enabled and/or activated with the authorization system  300  via the key code  24  stored in the authorization source  26  ( FIG.  6   ) or through the touchscreen display  92  of the control panel  90 . 
     According to various aspects, the support apparatus  10  may be updated with additional or new software related to the CLR function. In certain aspects, the authorization device  302  ( FIG.  4   ), such as a USB device, having the software update may be selectively coupled with the connector port  314  of the support apparatus  10  or the connector port  306  of the control panel  90  to program the control unit  22  with the CLR function. Additionally or alternatively, the support apparatus  10  may be in communication with the local server  320  or the remote server  350  ( FIG.  6   ) and can wirelessly receive the software update. In this way, the support apparatuses  10  may be manufactured with the CLR function or updated to provide the CLR function. 
     Referring still to  FIG.  18   , as well as to  FIG.  19   , the upper frame  44  of the support apparatus  10  may include various symbols  600  at the foot end  210  thereof, which allows the caregivers to efficiently determine whether the support apparatus  10  includes various features or functions, such as the CLR function. As illustrated in  FIG.  19   , the support apparatuses  10  that include the CLR function include a CLR symbol  602  at the foot end  210  of the upper frame  44 . As the caregiver moves past the support apparatus  10 , the caregiver can quickly and efficiently note that the support apparatus  10  includes the CLR function. This may be advantageous during surge events to transfer support apparatuses  10  between the MedSurge unit and the ICU that include the CLR function. 
     Referring again to  FIG.  3   , and still to  FIGS.  18  and  19   , the CLR function utilizes the rotation bladders  176  of the pneumatic system  130  to adjust the patient between a left side position, a center position, and a right side position, which may be referred to as patient positions or predefined positions. The pump  132  is in fluid communication with the rotation bladders  176 , which include the turn bladders  178 ,  180 ,  182 ,  184 , to adjust the turn bladders  178 ,  180 ,  182 ,  184  between the inflated condition and the deflated condition. For example, when the first and third turn bladders  178 ,  182  are adjusted to the inflated condition, the mattress  14  is angled to rotate the patient to the left side position. When the second and fourth turn bladders  180 ,  184  are adjusted to the inflated condition, the mattress  14  is angled to rotate the patient to the right side position. The CLR function provides continuous adjustment in cycles between the different patient positions over a predefined period of time. Each cycle may include an adjustment of the patient from the left side position, to the center position, to the right side position, and back to the center position. Each of the left side position, the center position, and the right side position may be held for a predefined hold time based on settings of the CLR function, generally provided by the caregiver. 
     Referring again to  FIG.  1   , as well as  FIGS.  18  and  19   , predefined conditions of the support apparatus  10  are generally to be satisfied prior to the activation of the CLR function. The predefined conditions relate to a position of the support apparatus  10  and the components coupled to the support apparatus  10 . For example, the predefined conditions may include a position of the upper frame  44 , including the head end segment  52  in a lowered position, a lowered knee position defined between the base segment  54  and the foot end segment  56 , the foot end segment  56  in a raised position, and the upper frame  44  in a level or flat condition. The support apparatus  10  generally includes a sensor assembly  604  with frame sensors  606  configured to sense the position of the upper frame  44 . 
     Additional predefined conditions may include the siderails  62  in a raised position, devices being disengaged from the connector port  314  on one or more of the siderails  62 , and an adjustment of the bed exit feature  106  to a lowest sensitivity level. A predefined number or all of the predefined conditions may be satisfied prior to the control unit  22  activating the CLR function. The predefined conditions generally relate to patient safety, minimizing interference between components as the mattress  14  adjusts between the different patient positions, and minimizing false alarms. 
     Generally, the patient is to be lying in a substantially flat or supine position on the support apparatus  10  during the CLR function. The level state or condition of the upper frame  44  provides a more comfortable side-to-side rotation of the patient. The sensor assembly  604  of the support apparatus  10  includes the frame sensors  606  configured to sense the position of the upper frame  44 , including various segments  52 ,  54 ,  56  thereof. The frame sensors  606  are configured to sense a position of the head end segment  52 , a position of the base segment  54 , a position of the foot end segment  56 , and/or the overall position of the upper frame  44  (e.g., level or not). The control unit  22  is configured to receive sensed information from the frame sensors  606  to confirm that the position of the upper frame  44  and the segments  52 ,  54 ,  56  satisfy the predefined conditions. If the predefined conditions are not satisfied, the control unit  22  may be configured to activate the actuation assembly  58  to adjust the upper frame  44  to the select position that satisfies the predefined condition (e.g., lowering the head end segment  52 , raising the foot end segment  56 , etc.). The adjustment with the actuation assembly  58  may be automatic or in response to a caregiver input. 
     Referring still to  FIGS.  1 ,  18 , and  19   , the siderails  62  being in the raised position provides additional safety to the patient during the side-to-side rotation. The sensor assembly  604  may also include siderail sensors  608  configured to sense a position of each siderail  62  of the support apparatus  10 . The control unit  22  is configured to receive sensed information from the siderail sensors  608  to confirm the siderails  62  are in the raised position and, therefore, satisfy the predefined conditions for activating the CLR function. 
     Further, the device engaged with the connector port  314  on one or more of the siderails  62  (generally one of the head siderails  64 ,  66 ) may be disposed within a movement path of the mattress  14  as the pneumatic system  130  adjusts to at least one of the right side position or the left side position. Any cord extending between the siderail  62  and the device may also affect the movement of the mattress  14  or the comfort of the patient. The device may be, for example, a personal device of the patient or a bed remote for controlling the support apparatus  10  and/or components of the patient room, etc. 
     The device may hinder movement of the mattress  14 , be moved by the mattress  14 , and/or be disengaged from the siderail  62  by the movement of the mattress  14 , and, therefore, disengagement of the device is advantageous prior to the activation of the CLR function. The control unit  22  may be configured to sense when the device is engaged or disengaged with the connector port  314 . Further, the control unit  22  may be configured to sense when the cord, such as a power cord, is engaged with the connector port  314  when the cord is not engaged with the device. 
     Referring still to  FIGS.  18 , and  19   , adjusting the bed exit feature  106  may also be one of the predefined conditions to be satisfied before activating the CLR function. The adjustment of the sensitivity of the bed exit feature  106  minimizes false alarms during the activation of the CLR function. The bed exit feature  106  includes the force sensors  102  configured to monitor the position and movement of the patient on the support apparatus  10 . Generally, the control unit  22  is configured to generate an alert in response to the movement of the patient that indicates that the patient is attempting to exit the support apparatus  10 . 
     When operating independently, the bed exit feature  106  generally has three sensitivity levels. The first, and highest, sensitivity level results in an alert being generated when the patient moves from a lying position to a sitting position. The second, middle, sensitivity level results in the alert being generated when the patient moves toward an edge of the mattress  14 . The third, and lowest, sensitivity level results in the alert being generated when the patient exits the bed (e.g., the force sensors  102  no longer sense the weight of the patient). The sensitivity level determines at what stage of movement (from the lying position to fully exiting the bed) triggers the bed exit alert generation. 
     When the CLR function is operating in a preview mode or an active mode, the pneumatic system  130  moves the patient in a side-to-side motion, which may trigger the bed exit feature  106  at the highest or middle sensitivity levels. Accordingly, the bed exit feature  106  may be adjusted by the caregiver to the lowest sensitivity level when activating the CLR function. This may be advantageous to minimize or prevent false alarms from the bed exit feature  106  caused by the CLR function. 
     Referring still to  FIG.  18   , an additional non-limiting example of a feature that may be enabled or activated through the touchscreen display  92  of the control panel  90  includes the incontinence detection system  150 , which may also utilize the CLR function. The incontinence detection system  150  may be an example of the integrated feature  20  ( FIG.  2   ) that is installed during the manufacture of the support apparatus  10  or an example of the removable feature  140  ( FIG.  2   ) added onto the support apparatus  10 . The incontinence detection system  150  includes multiple components to sense an incontinence event and provide a timely alert to the caregiver to maximize the comfort of the patient. 
     The incontinence detection system  150  includes a monitor assembly  614  coupled to the support apparatus  10 . The monitor assembly  614  generally includes a control unit having a processor, a memory, and other control circuitry. Instructions or routines are stored in the memory and executable by the processor. The monitor assembly  614  may include communication circuitry for bidirectional wired or wireless communication. The monitor assembly  614  may be in communication with the control unit  22  of the support apparatus  10  and/or other systems of the medical facility directly or through the communication network  354  ( FIG.  6   ). 
     The incontinence detection system  150  includes the pad  154  with the moisture sensors  152  and which are configured to be positioned on the mattress  14  under the patient. The moisture sensors  152  are configured to sense moisture levels or the incontinence event. The monitor assembly  614  is in communication with the moisture sensors  152 . When the moisture sensors  152  sense moisture and communicate sensed information to the monitor assembly  614 , the monitor assembly  614  is configured to activate the indicator  156  on the support apparatus  10  or communicate an alert to a nurse call system or other systems of the medical facility. 
     Referring still to  FIG.  18   , as well as  FIG.  20   , the integrated features  20 , such as the CLR function, may be enabled and/or activated via the touchscreen display  92  of the control panel  90 . The control panel  90  is configured to receive inputs from the caregiver for controlling the support apparatus  10  and features or functions thereof. Additionally, as illustrated in  FIG.  20   , a home screen  620  displayed on the touchscreen display  92  of the control panel  90  is configured to provide information about the patient, active functions, the variety of information  226 , and the selectable icons  228 . For example, the home screen  620  illustrated in  FIG.  20    includes the head angle measurement  230 , the active alert  232  that shows the sensitivity level of the bed exit feature  106 , and the vital signs information  234  with the heart rate  236  and the respiration rate  238 . The home screen  620  also includes the head angle icon  250 , the sitting position icon  252 , the stand assist icon  254 , a frame adjustment icon  622 , and two length adjustment icons  258 , which include an extend icon  624  and a retract icon  626 . Further, as illustrated on a side of the touchscreen display  92  of  FIG.  20   , the home screen  620  includes the home icon  262 , the scale icon  266 , the vital signs icon  268 , a CLR icon  628 , and an arrow icon  630  for viewing additional icons  228 . 
     The order of the icons  228 , particularly those on the side of the touchscreen display  92  under the home icon  262 , are configured to be automatically adjusted by the control unit  22  in response to activated features. For example, when the support apparatus  10  does not include the CLR function, the CLR icon  628  is not included on the touchscreen display  92 . When the CLR function is included in the support apparatus  10  but is disabled, the CLR icon  628  may be lower in the order, generally accessible by selecting the arrow icon  630 . When the CLR function is enabled and active, the CLR icon  628  may be closer to the home icon  262  to provide more convenient access to information related to the CLR function. The control unit  22  is configured to prioritize the icons  228  based on predefined priority, activation status, etc. 
     Referring still to  FIG.  20   , as well as  FIG.  21   , the CLR function may be available on the support apparatus  10 , as indicated by the appearance of the CLR icon  628 , but may be in an enabled state or a disabled state. If the CLR function is disabled when the caregiver selects the CLR icon  628 , the control unit  22  is configured to generate a function disabled notification screen  638 , as illustrated in  FIG.  21   . The function disabled notification screen  638  is generated by the control unit  22  and displayed on the touchscreen display  92 . The function disabled notification screen  638  alerts the caregiver that the CLR function is available but is currently in the disabled state. The caregiver may select the “OK” icon  640 , as illustrated in  FIG.  20   , which may cause the control unit  22  to return to the home screen  620 . 
     Referring to  FIG.  22   , in order to enable the CLR function, the caregiver may select the settings icon  270 , which may be accessed by selecting the arrow icon  630  on the home screen  620  ( FIG.  20   ). Selecting the settings icon  270  results in the control unit  22  generating and displaying an apparatus settings screen  642 . As illustrated in  FIG.  22   , the apparatus settings screen  642  includes multiple selectable icons  644  for adjusting, controlling, enabling, and activating various features and functions of the support apparatus  10 , including the CLR function, which is indicated by a rotation icon  646 . 
     Referring still to  FIG.  22   , as well as  FIG.  23   , upon selection of the rotation icon  646 , the control unit  22  is configured to generate at least one confirmation screen  648 , which allows the caregiver to confirm the enablement or disabling of the CLR function. As illustrated in  FIG.  23   , the confirmation screen  648  may include an enable icon  650 . Upon selection of the enable icon  650 , the caregiver may then select a cancel icon  652 , which maintains the CLR function in the disabled state, and an accept icon  654 , which adjusts the CLR function to the enabled state. It is contemplated that the control unit  22  may generate a first confirmation screen  648  with the enable icon  650  and, upon selection of the enable icon  650 , may generate a second confirmation screen  648  with the cancel icon  652  and the accept icon  654 . Additionally or alternatively, the cancel icon  652  and the accept icon  654  may be on a single confirmation screen  648  with the enable icon  650 . In such examples, the cancel icon  652  and the accept icon  654  may be selectable after the selection of the enable icon  650 . The selection of the enable icon  650  and the accept icon  654  provides two-step authorization or confirmation to enable the CLR function. Selection of either the cancel icon  652  or the accept icon  654  generally returns the caregiver to the apparatus settings screen  642  ( FIG.  21   ). 
     Referring still to  FIGS.  21 - 23   , a process for disabling the CLR function is generally similar to the process for enabling the CLR function. For example, to fully disable the CLR function, the caregiver navigates through the apparatus settings screen  642  and selects the rotation icon  646 . The control unit  22  is configured to generate at least one confirmation screen  648 , which includes a disable icon. Upon selection of the disable icon, the caregiver may then select a cancel icon or an accept icon. The selection of the disable icon and the accept icon provides two-step authorization to disable the CLR function. It is contemplated that the control unit  22  may generate a single confirmation screen  648  with the various icons or may generate a first confirmation screen  648  with the disable icon and, upon selection of the disable icon, may generate a second confirmation screen  648  with the cancel icon and the accept icon. It is contemplated that multi-step authorization, utilizing two or more inputs from the caregiver, may be utilized for enabling and/or disabling the CLR function. 
     Referring to  FIG.  24   , the control unit  22  may be configured to seek the key code  24  ( FIG.  6   ) to enable, or disable, the CLR function. In such examples, the control unit  22  is configured to generate an authorization screen  660 , which informs the caregiver that the key code  24  has been sought and received, as illustrated in  FIG.  24   . If the key code  24  is not received, the control unit  22  is configured to generate the authorization screen  660  informing the caregiver that the key code  24  was not received and the CLR function remains in the disabled condition. The enablement through the two-step authorization and the key code  24  may be used independently of one another or in combination. For example, the caregiver may override the lack of the key code  24  through another input provided to the control panel  90 . 
     Referring again to  FIG.  22   , the apparatus settings screen  642  includes a software update icon  662 . The software update icon  662  may be utilized to seek or process the software update relating to the CLR function. For example, selecting the software update icon  662  may prompt the control unit  22  to seek communication with the local server  320  and/or the remote server  350  ( FIG.  6   ) to receive the updated software. Additionally or alternatively, the caregiver may couple the authorization device  302  with the connector port  314  ( FIG.  6   ) and select the software update icon  662  to being downloading the software update from the authorization device  302 . Additional or alternative software updates may be received by using the software update icon  662  on the control panel  90 . 
     Referring to  FIG.  25   , when the CLR function is enabled and the caregiver selects the CLR icon  628 , the control unit  22  is configured to generate and display a rotation settings screen  668 . The rotation settings screen  668  is configured to display current rotation settings and receive inputs from the caregiver to adjust the settings of the CLR function. In the example illustrated in  FIG.  25   , the settings that may be adjusted include a rotation level  670 , a left side status  672 , a right side status  674 , and a hold time  676 . The rotation settings screen  668  also includes a preview icon  678 , for activating the CLR function in the preview mode, a start icon  680 , for activating the CLR function in the active mode, and a history icon  682 , for viewing a history of the CLR function. Additionally or alternatively, the rotation settings screen  668  may include a left side graphic  684 , a right side graphic  686 , a center graphic  688  that illustrate the patient positions for the CLR function. 
     For the rotation level  670 , the caregiver may choose between predefined settings, such as full rotation or moderate rotation by selecting a full icon  690  or a moderate icon  692 , respectively. The rotation level  670  is determined by an amount the rotation bladders  176  ( FIG.  18   ) are inflated. For example, when the CLR function is set to provide the full rotation, the rotation bladders  176  may inflate to, for example, about 100% of an inflation capacity. When the CLR function is set to the moderate rotation, the rotation bladders  176  may inflate to, for example, about 60% of the inflation capacity. The exemplary 100% and 60% inflation are not limiting, such that the percentage or amount of inflation may be any practicable values without departing from the teachings herein. 
     Referring still to  FIG.  25   , for the right side status  674  and the left side status  672 , the caregiver may activate or deactivate the rotation to a certain side. In the illustrated example of  FIG.  25   , the right side turn is activated while the left side turn is deactivated. In such settings, the patient is configured to rotate between the right side position and the center position without rotating to the left side position. For certain patients or certain functions, it may be advantageous to deactivate one of the side rotations, which then provides the CLR function where the patient rotates between a single side position and the center position. 
     Further, the rotation settings screen  668  generally includes the left side graphic  684 , which is a graphical representation of the left side position, the center graphic  688 , which is a graphical representation of the center position, and the right side graphic  686 , which is a graphical representation of the right side position. An arrow  694 ,  696  is positioned proximate to each side graphic  684 ,  686 , respectively. The arrows  694 ,  696  show the direction of rotation along with the chosen level of rotation. In the example illustrated in  FIG.  25   , the arrows  694 ,  696  are fully filled, solid, or colored, indicating full rotation to each side position. If the moderate rotation was selected, the arrows  694 ,  696  may be partially solid. This provides another indication of the rotation level  670 . It is contemplated that when one of the side positions is in the deactivated state, the graphic  684 ,  686  and/or the arrow  694 ,  696  may be dimmed, grey in color, or otherwise indicated as deactivated. 
     With reference still to  FIG.  25   , as well as to  FIG.  26   , the rotation settings screen  668  also includes a hold time icon  700 , which displays the currently selected hold time  676  for the CLR function. The hold time  676  is the period of time that the patient is held or maintained in each activated patient position. In the illustrated example, the hold time  676  is 15 minutes. Upon selection of the hold time icon  700 , the control unit  22  is configured to generate a timing screen  702 , which allows the caregiver to adjust the hold time  676 . The timing screen  702  may be overlaid on the rotation settings screen  668  or may be a separate screen. The timing screen  702  includes a timing bar  704  having predefined timing intervals. As illustrated in the example of  FIG.  26   , the predefined timing intervals on the timing bar  704  include three minutes, six minutes, 10 minutes, and 15 minutes. 
     To adjust the hold time  676 , the caregiver may select a left arrow  706  or right arrow  708  to adjust a slider  710  along the timing bar  704  between the various predefined intervals. Additionally or alternatively, the slider  710  may be a touch-sensitive feature on the touchscreen display  92 . In such examples, the caregiver may select the slider  710  and move or slide the slider  710  along the timing bar  704  to the selected time interval. The timing screen  702  may be enlarged compared to traditional designs, which may be advantageous for allowing caregivers wearing personal protection equipment (PPE), such as gloves, to more conveniently adjust the hold time  676  via the touchscreen display  92  while wearing the PPE. The caregiver may touch a location on the touchscreen display  92  away from the timing screen  702  to confirm the selected hold time  676  or may select a confirm or back button to return to the rotation settings screen  668 . 
     Referring again to  FIG.  25   , once the rotation settings have been selected, the caregiver may select the preview icon  678  to activate the CLR function in the preview mode. The preview mode provides a shortened cycle of the selected settings of the CLR function, allowing the caregiver to efficiently confirm the selected settings. Additionally, the preview mode may be advantageous for allowing the caregiver to confirm the position of the patient, as well as tubes and lines extending to the patient during the CLR function. 
     Referring still to  FIG.  25   , as well as to  FIG.  27   , upon selection of the preview icon  678 , the control unit  22  is configured to generate a caution screen  720  to prompt the caregiver to confirm select conditions are satisfied prior to the activation of the preview mode. Generally, the caution screen  720  indicates conditions that are not sensed or determined by the control unit  22 . For example, as illustrated in  FIG.  27   , the caution screen  720  includes an alert for confirming a bed remote or the pendant  146  ( FIG.  2   ) has been removed from the inside of the siderail  62 . 
     Generally, the bed remote or the pendant  146  may be coupled to one of the siderails  62  for convenient access by the patient on the support apparatus  10 . The bed remote or pendant  146  is typically selectively hooked or coupled onto the siderail  62  in a manner that is not sensed by the control unit  22 . Accordingly, the control unit  22  may not be able to determine whether the bed remote or the pendant  146  is hooked on the siderail  62  so the caution screen  720  prompts the caregiver to confirm. When hooked on the siderail  62 , the pendant  146  or bed remote may be within the movement path of the mattress  14  during the CLR function, which can cause the bed remote or pendant  146  to hinder the CLR function or to be accidentally disengaged from the siderail  62 . The caregiver may select a cancel icon  722  to return to the rotation settings screen  668  or a continue icon  724  to proceed with the preview mode. 
     Referring to  FIGS.  28  and  29   , after navigating through the caution screen  720  in  FIG.  27    and selecting the continue icon  724 , the control unit  22  is configured to generate at least one of a start failure screen  726 , as illustrated in  FIG.  28   , and a start confirmation screen  728 , as illustrated in  FIG.  29   . The control unit  22  is configured to utilize sensed information from the sensor assembly  604  and from the connector port  314  to determine whether the predefined conditions are satisfied. A conditions list  730  is included on both the start failure screen  726  and the start confirmation screen  728 . In the illustrated example of  FIGS.  28  and  29   , the predefined conditions on the conditions list  730  to be satisfied prior to activation of the CLR function include the head end being lowered, the knee being lowered, which may also encompass the foot end  210  being raised, the upper frame  44  being level, the siderails  62  being raised, and the device being disengaged from the connector port  314 . 
     The control unit  22  is configured to generate the start failure screen  726  when at least one of the predefined conditions is not satisfied. In the example illustrated in  FIG.  28   , the lowered head and the lowered knee conditions are satisfied, as indicated by the checkmark indicators  732 . In comparison, the level upper frame  44 , the raised siderails  62 , and the disengaged device conditions are not satisfied, as indicated by the “X”-indicators  734 . When at least one of the predefined conditions is not satisfied, there is generally no option to continue with the preview mode. The caregiver may select a cancel icon  736 , which returns the caregiver to the apparatus settings screen  642  ( FIG.  22   ) to allow the caregiver to adjust aspects of the support apparatus  10  to satisfy the predefined conditions. 
     Referring again to  FIG.  29   , after selection of the continue icon  724  in the caution screen ( FIG.  27   ) or adjusting the settings after viewing the start failure screen  726 , the control unit  22  is configured to generate the start confirmation screen  728 . The start confirmation screen  728  is generated when each of the predefined conditions is satisfied. The start confirmation screen  728  shows the conditions list  730  with each of the predefined conditions with the checkmark indicator  732 , indicating that each condition is satisfied. Additionally, the start confirmation screen  728  includes a continue icon  738 , which the caregiver may select to proceed to the preview mode. 
     With reference to  FIG.  30   , the control unit  22  is configured to generate a preview notification  750 , which notifies the caregiver about the function of the preview mode. The preview notification  750  may reduce human error in starting the preview mode rather than the active mode of the CLR function. The preview notification  750  generally indicates that the preview mode it utilized for confirmation of the settings for the CLR function and is not the active mode of the CLR function. The caregiver may select a cancel icon  752  to return to the rotation settings screen  668  ( FIG.  25   ) or may select a preview icon  754  to continue toward activating the preview mode of the CLR function. 
     With reference to  FIGS.  31 - 33   , the control unit  22  may be configured to prompt the caregiver about various actions related to the bed exit feature  106 . The status and sensitivity level of the bed exit feature  106  may be adjusted prior to activation of the CLR function. If the bed exit feature  106  is enabled but not currently active, the control unit  22  is configured to generate an exit activation screen  756 , as illustrated in  FIG.  31   . The exit activation screen  756  is configured to notify the caregiver that an out-of-bed or bed exit mode of the bed exit feature  106  for the support apparatus  10  is being activated. The exit activation screen  756  also notifies the caregiver of the sensitivity level of the bed exit feature  106 , which is the lowest sensitivity (e.g., configured to generate the alert when the patient exits the support apparatus  10 ). 
     If the bed exit feature  106  is activated at the highest or middle sensitivity level, the control unit  22  is configured to generate an exit adjustment screen  758 , as illustrated in  FIG.  32   . The exit adjustment screen  758  illustrates the change in sensitivity level to the lowest sensitivity level. The exit adjustment screen  758  may display a high sensitivity graphic  760  and an arrow pointing to a low sensitivity graphic  762 . Additionally or alternatively, the exit adjustment screen  758  may display a middle sensitivity graphic  764  and an arrow pointing to the low sensitivity graphic  762 . It is contemplated that the exit adjustment screen  758  may display both adjustment indications (high-to-low and mid-to-low) or a single adjustment indication based on the actual adjustment of the support apparatus  10 . 
     If the bed exit feature  106  is not enabled, the control unit  22  may generate an exit error alert  766 , as illustrated in  FIG.  33   . The exit error alert  766  is configured to notify the caregiver that the bed exit mode is deactivated and will not provide any alerts, even if the patient exits the support apparatus  10 . The caregiver may select a continue icon  768 , to proceed without activation of the bed exit mode, or a cancel icon  770 , which allows the caregiver to activate the bed exit feature  106 . If the exit error alert  766  remains displayed on the control panel  90 , the control unit  22  may be configured to generate an alert to prompt action by the caregiver. In non-limiting examples, the control panel  90  may include a speaker which emits an audible alert at predefined intervals until the caregiver selects the cancel icon  770  or the continue icon  768 . The audible alerts may increase in volume at each interval. Additional or alternative audible, visual, or haptic alerts may also be utilized. 
     With reference to  FIG.  34   , if the caregiver selects the cancel icon  770  in the exit error alert  766  of  FIG.  33   , the control unit  22  is configured to generate and display a bed exit settings screen  780 . The bed exit settings screen  780  includes options for setting the sensitivity level of the bed exit feature  106 . In the example illustrated in  FIG.  34   , the options include a high sensitivity icon  782 , a middle sensitivity icon  784 , a low sensitivity icon  786 , and an off icon  788 . When utilizing the CLR function, the high sensitivity icon  782  and the middle sensitivity icon  784  may be dimmed, grey, or otherwise indicated as deactivated such that these sensitivity levels may not be selected by the caregiver. After activating the bed exit feature  106 , the caregiver may navigate through the various screens displayed on the control panel  90  toward the preview mode. 
     Referring to  FIG.  35   , after activating the bed exit feature  106  or continuing without activating the bed exit feature  106 , the control unit  22  is configured to activate the pneumatic system  130  in the preview mode for the CLR function. In the preview mode, the pneumatic system  130  is adjusted through one cycle of the CLR function. One cycle for the preview mode generally adjusts the patient to the right side position, to the center position, and to the right side position. This allows the caregiver to view the patient in each of the three patient positions for the CLR function. Further, in the preview mode, the CLR function does not follow the hold time  676  in any of the patient positions. In this way, the patient is moved continually through the three patient positions. This provides a faster time to cycle through the three patient positions, which may be advantageous for allowing the caregiver to check or confirm the position of the patient, the position of any tubes or lines extending to the patient, and any adjustments for the tubes and lines to prevent pulling, disengagement, etc. during rotation. 
     While the pneumatic system  130  is operating in the preview mode for the CLR function, the control unit  22  is configured to generate a preview screen  800  including a stop preview icon  802  and the three position graphics  684 ,  686 ,  688 . The position graphics  684 ,  686 ,  688  illustrate a left side, a center, and a right side, which correspond with the left side position, the center position, and the right side position of the patient. The control unit  22  is configured to show a rotation status by distinguishing or differentiating the graphic for the current position of the patient. As illustrated in  FIG.  35   , the left side graphic  684  is highlighted to indicate to the caregiver that the patient is currently in the left side position. The preview screen  800  is configured to update concurrently with the adjustment of the pneumatic system  130 . 
     Referring still to  FIG.  35   , as well as to  FIG.  36   , as the CLR function in the preview mode adjusts the pneumatic system  130  through the single cycle of patient positions, the preview screen  800  is configured to show the rotation status by distinguishing or differentiating past positions of the patient as well as the current position. As best illustrated in  FIG.  36   , the patient has been rotated to the left side position and the center position, which is indicated by the differentiation or distinguishing of the left side graphic  684  and the center graphic  688 . The preview screen  800  is configured to update concurrently with the adjustment of the pneumatic system  130  to the different patient positions. 
     In certain aspects, one of the side positions may be deactivated such that the patient does not rotate to that side position. In the example illustrated in  FIG.  36   , the right side position is deactivated. In the preview screen  800 , the right side graphic  686  is dimmed, grey, or otherwise indicated as deactivated to illustrate that the patient is not going to be rotated to the right side position. The preview screen  800  displayed on the control panel  90  is configured to mirror the actions being conducted by the pneumatic system  130  for the CLR function in the preview mode. 
     The preview mode does not include the hold times  676  but includes continuous motion between the selected positions. This shortened cycle may be advantageous for the caregiver to confirm the position of the patient, as well as any attachments to the patient. For example, the patient may have various lines or tubing that extend from a device to the body of the patient. The rotation of the patient during the CLR function may adjust the lines or tubing to bend, kink, pull, or otherwise affect the treatment or comfort of the patient. The preview mode allows the caregiver to monitor the lines and tubing of the patient and adjust any lines or tubing that may be affected by the CLR function prior to the CLR function being adjusted to the active mode. 
     The stop preview icon  802  may be selected to fully stop the preview or pause the preview. Stopping and restarting the preview mode may be advantageous for the caregiver to adjust the patient, tubing, lines, or devices. Accordingly, the caregiver may repeatedly stop and start the preview mode or repeat the preview mode until the caregiver is satisfied with the settings. 
     As illustrated in  FIG.  37   , during the preview mode of the CLR function, if the support apparatus  10  is adjusted such that at least one of the predefined conditions is no longer satisfied, the control unit  22  is configured to pause or suspend the preview mode. In this way, the pneumatic system  130  is at least temporarily deactivated to stop the CLR function. Additionally, the control unit  22  is configured to generate and display a suspension screen  804  on the control panel  90 . The suspension screen  804  indicates which of the predefined conditions are no longer satisfied. 
     For example, the suspension screen  804  generally includes the conditions list  730  with the checkmark indicators  732  and the “X”-indicators  734 . The suspension of the CLR function may last for a predefined period of time, which is 15 minutes in the example illustrated in  FIG.  37   . After the predefined period of time has elapsed, the control unit  22  is configured to generate an alert to remind the caregiver the preview mode of the CLR function has been suspended and to prompt action by the caregiver. The alert may be an audible alert at intervals that increases in volume over time or any other audible, haptic, or visual alert. The caregiver may select a cancel icon  806  to return to the apparatus settings screen  642  to adjust aspects of the support apparatus  10  to again satisfy the predefined conditions. 
     Returning to  FIG.  25   , upon completion or cancellation of the preview mode, the control unit  22  is configured to return to the rotation settings screen  668 . The caregiver may make any adjustments and may again proceed through the various screens to confirm the settings with the preview mode. Once the caregiver is satisfied with the CLR function and settings, the caregiver may then select the start icon  680 , which is configured to adjust the pneumatic system  130  into the active mode to provide the CLR function for a predefined period of time. 
     The predefined period of time for the CLR function in the active mode may be any practicable amount of time based on the treatment or care of the patient. The caregiver may select this period of time in the rotation settings screen  668  or through the apparatus settings screen  642  ( FIG.  22   ). The time for the CLR function to remain active may be measured in minutes or hours, for up to about 24 hours. 
     After selecting the start icon  680 , the control unit  22  may be configured to generate various screens to caution, notify, or alert the caregiver of a variety of information, similar to those described with reference to  FIGS.  27 - 29    and  FIGS.  31 - 33   . The control unit  22  may caution the caregiver to confirm certain predefined conditions are satisfied that the control unit  22  is unable to confirm (similar to  FIG.  27   ), indicate which predefined conditions are not satisfied (similar to  FIG.  28   ), and indicate that the predefined conditions are all satisfied (similar to  FIG.  29   ). Additionally, the control unit  22  may adjust the bed exit feature  106  to an activated state (similar to  FIG.  30   ), adjust the sensitivity level of the bed exit feature  106  (similar to  FIGS.  31  and  32   ), and prompt confirmation to proceed without the bed exit feature  106  (similar to  FIG.  33   ). While making these adjustments, the control unit  22  is configured to adjust aspects of the support apparatus  10  and notify the caregiver through the touchscreen display  92  of the control panel  90 . 
     Further, the control unit  22  may be configured to seek the key code  24  ( FIG.  6   ) to adjust the CLR function of the pneumatic system  130  to the active mode. In such examples, the control unit  22  is configured to generate the authorization screen  660  (similar to  FIG.  24   ), which informs the caregiver that the key code  24  has been sought and received. If the key code  24  is not received, the control unit  22  is configured to generate the authorization screen  660  informing the caregiver that the key code  24  was not received and the CLR function will not start. The activation through multiple selections on the touchscreen display  92  and the key code  24  may be used independently of one another or in combination. For example, the caregiver may override the lack of key code  24  through another input provided to the control panel  90 . 
     Referring to  FIG.  38   , once the CLR function is in the active mode, the control unit  22  may generate and display an updated home screen  810 . The updated home screen  810  is configured to include a stop rotation icon  812 . The selectable icons  228  on the updated home screen  810  are shifted to accommodate the stop rotation icon  812  in a prominent location on the touchscreen display  92 . This allows the caregiver to quickly and efficiently stop the CLR function directly from the updated home screen  810  without navigating through multiple secondary or subsequent screens. Further, the updated home screen  810  includes an active CLR graphic  814  proximate to a connectivity graphic  816 . The active CLR graphic  814 , also referred to as the active status graphic  814  for the CLR function, provides an additional indication to the caregiver that the CLR function is enabled and currently rotating the patient in the active mode (e.g., in progress). 
     Referring still to  FIG.  38   , as well to  FIG.  39   , the caregiver can select the CLR icon  628  on the updated home screen  810  to view status information about the CLR function. The control unit  22  is configured to generate and display a rotation status screen  818  in response to the selection of the CLR icon  628  when the CLR function is active. Information on the rotation status screen  818  may include a current position indication  820  and a status bar  822 , which indicates elapsed time  824  and remaining time  826  in the current patient position, as well as the hold time  676 . For example, the current position indication  820  shows the patient in the left side position, and the status bar  822  illustrates that the patient has been in the left side position for over half (e.g., about seven minutes) of the hold time  676 , which is 10 minutes. It is contemplated that the status bar  822  may also include intervals to further note the elapsed time  824  and remaining time  826 . 
     The rotation status screen  818  also shows the rotation level  670  for the active CLR function, which is indicated as moderate rotation in the illustrated example of  FIG.  39   . The rotation status screen  818  also includes the position graphics  684 ,  686 ,  688 , with one graphic  684  differentiated or distinguished. In the example of  FIG.  39   , the left side graphic  684  is differentiated to indicate that the patient is currently in the left side position. The arrangement of the position graphics  684 ,  686 ,  688  also indicates the next position for the patient. As the cycle between the patient positions is continuous in the active mode, generally a single graphic is differentiated at a single time, which is different from the preview mode (as illustrated in  FIG.  35   ). The rotation status screen  818  is configured to be updated concurrently with the adjustment of the pneumatic system  130  between the patient positions. If one of the positions is deactivated, the corresponding graphic on the rotation status screen  818  may be dimmed, grey, or otherwise indicated as deactivated, similar to the preview screen  800  (as illustrated in  FIG.  36   ). The rotation status screen  818  also indicates an elapsed time  828  since the CLR function was adjusted to the active mode and may also include time remaining for the active mode of the CLR function. The elapsed time  828  is generally based on a 24-hour cycle starting at midnight. 
     Further, a patient position graphic  830  is also included on the rotation status screen  818 . The patient position graphic  830  is illustrative of a patient in one of the three positions for the CLR function on the support apparatus  10  with an arrow  832  indicating a rotation direction. In the example illustrated in  FIG.  39   , the patient position graphic  830  illustrates the patient rotated to the left side position with the arrow  832  pointing to the left side of the patient. 
     The rotation status screen  818  further includes a stop rotation icon  834 , which allows the caregiver to stop the CLR function. Accordingly, there are multiple screens displayed on the control panel  90  that provide the option for the caregiver to stop the CLR function. Upon activation of the CLR function and/or selection of the CLR icon  628 , the rotation status screen  818  may be generated and displayed for a predefined period of time. The predefined period of time may be several minutes, such as, for example, a time up to about two minutes. After the predefined period of time has elapsed, the control unit  22  may automatically display the updated home screen  810  (as illustrated in  FIG.  38   ). 
     Referring now to  FIG.  40   , after a predefined period of inactivity on the control panel  90  (e.g., free of receiving inputs), the control unit  22  may adjust the touchscreen display  92  to a sleep screen  840 , which is configured to conserve energy. The sleep screen  840  may include a variety of information helpful to the caregiver, including information about the patient, such as the head angle measurement  230 , the heart rate  236 , and the respiration rate  238 , and active functions, such as the bed exit icon  264  and the CLR icon  628 . The sleep screen  840  compiles information for quick review by the caregiver. 
     Referring to  FIG.  41   , when the caregiver selects the stop rotation icon  834  to stop the CLR function, for example on the updated home screen  810  ( FIG.  38   ) or the rotation status screen  818  ( FIG.  25   ), the control unit  22  is configured to generate a stop confirmation screen  842 . The stop confirmation screen  842  provides a “no” icon  844  and a “yes” icon  846  to confirm the change to the CLR function. This provides a secondary step-two authorization to minimize or prevent inadvertent stopping of the CLR function. If the caregiver selects the “no” icon  844 , the control screen is configured to return to the updated home screen  810  and the CLR function is configured to remain in the active mode. If the caregiver selects the “yes” icon  846 , the CLR function is adjusted to an off mode. When in the off mode, the CLR function remains enabled to be reactivated at a later time. 
     Referring again to  FIG.  25   , as well as to  FIG.  42   , the rotation status screen  818  also includes the history icon  682 . The caregiver may select the history icon  682 , which results in the control unit  22  generating and displaying a history screen  850 , as illustrated in  FIG.  42   . The history screen  850  compiles the information about the CLR function for the patient, the support apparatus  10 , for a predefined period of time, etc. In the example illustrated in  FIG.  42   , the history screen  850  includes start data  852  for each time the CLR function was adjusted to the active mode, stop data  854  for each time the CLR function was adjusted to the off mode, and settings information  856  about the rotation level  670 . The control unit  22  may store history data (e.g., data  852 ,  854  and information  856 ) in the memory  82  ( FIG.  18   ) and/or retrieve the history data from an electronic medical record of the patient generally stored in the local server  320  or the remote server  350  ( FIG.  6   ). The caregiver may return to the rotation settings screen  668  ( FIG.  25   ) by selecting a back icon  858 . 
     Referring to  FIG.  43   , in certain aspects, the control unit  22  may be configured to generate and display at least one help screen  870  on the touchscreen display  92  after selecting the help feature  272  on the home screen  620  ( FIG.  20   ). The help screen  870  may provide the caregiver with information on how to operate the CLR function, as well as other functions and features of the support apparatus  10 . The help screen  870  may include help icons  872  related to the CLR function. Upon selection of one of the help icons  872 , the control unit  22  is configured to display more information for the caregiver. Such information may include how to start the preview mode, how to start the active mode, how to adjust the bed exit feature  106 , what features are included in the predefined conditions, etc. Selecting an arrow  874  may display additional help icons  872 , while a back arrow  876  extends the caregiver to the home screen  620  ( FIG.  20   ). 
     Referring to  FIG.  44   , and with further reference to  FIGS.  1 - 43   , a method  900  for authorizing the activation of the CLR function includes step  902  of providing the support apparatus  10  with the CLR function. Step  902  may include providing the support apparatus  10  that had the CLR function installed during manufacturing. Additionally or alternatively, step  902  may include performing the software update on the support apparatus  10  to install the CLR function. The caregiver can confirm the support apparatus  10  has the CLR function through the CLR icon  628  on the touchscreen display  92  of the control panel  90  and/or the CLR symbol  602  on the upper frame  44 . 
     In step  904 , the caregiver enables the CLR function. The caregiver may access the apparatus settings screen  642  to select the rotation icon  646  and navigate through the confirmation screen  648  to enable the CLR function. Additionally or alternatively, the control unit  22  may seek the key code  24  from the authorization source  26  to confirm authorization for enabling the CLR function.
