Description:
BACKGROUND OF THE INVENTION 
       [0001]    The subject matter disclosed herein relates to a patient monitoring system with a health status indicator. 
         [0002]    Multi-patient displays enable a single technician to generally simultaneously monitor a plurality of patients. Multi-patient displays are commonly implemented in centralized patient monitoring systems wherein a plurality of technicians collectively monitor a large number of patients from a single location, and in hallway display systems wherein patient data pertaining to a plurality of different patients is visually conveyed in a hospital hallway. 
         [0003]    Some conventional multi-patient displays are configured to enable a single technician to monitor as many as 96 patients. One problem with such conventional multi-patient displays is that it can be difficult to efficiently evaluate all the displayed information and identify those specific patients requiring attention.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0011]    In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments that may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical and other changes may be made without departing from the scope of the embodiments. The following detailed description is, therefore, not to be taken as limiting the scope of the invention. 
         [0012]    Referring to  FIG. 1 , a patient monitoring system  10  is shown in accordance with one embodiment. The patient monitoring system  10  includes a computer  12  and a display  14 . The patient monitoring system  10  will hereinafter be described in accordance with an embodiment as a centralized patient monitoring system  10  adapted to enable a single technician  16  to generally simultaneously monitor a plurality of patients  18   a - 18   n,  however, it should be appreciated that other monitoring systems may be envisioned. Similarly, the display  14  will hereinafter be described in accordance with an embodiment as a multi-patient display  14 , however, other display types may also be envisioned. According to one alternate embodiment, the display  14  may comprise a single-patient display. 
         [0013]    The computer  12  is connected to a plurality of discrete patient monitoring systems  20   a - 20   n.  The discrete patient monitoring systems  20   a - 20   n  are each configured to monitor one of the patients  18   a - 18   n,  to generate patient data based on the specific characteristics being monitored, and to transmit the patient data to the computer  12 . In a non-limiting manner, the discrete patient monitoring systems  20   a - 20   n  may each comprise an electrocardiograph, a blood pressure monitor, a thermometer, and/or a pulse oximeter. Correspondingly, the patient data generated by the patient monitoring systems  20   a - 20   n  may comprise electrocardiogram (ECG) data, blood pressure data, temperature data, and/or pulse data. 
         [0014]    The computer  12  is configured to evaluate the patient data from the patient monitoring systems  20   a - 20   n  in order assess each patient&#39;s health. In a non-limiting manner, the computer  12  may be configured to assess patient health by analyzing the magnitude of the patient data and/or the data&#39;s rate of change. As an example, heart rate data falling below a first predetermined value may indicate moderate patient health and the need for attention in the near future, whereas heart rata data falling below a second predetermined value may indicate poor patient health and the need for immediate attention. 
         [0015]    The computer  12  is also configured to generate a user interface for each monitored patient. According to one embodiment, each user interfaces comprises raw patient data and a visual health status indicator. A plurality of exemplary user interfaces  100 - 130  and health status indicators  132 - 138  are shown in  FIG. 2 . As will be described in more detail hereinafter, each health status indicator may be implemented to visually convey a wide range of patient health assessments such as, for example, the range extending from very good health to critically poor health. 
         [0016]    The multi-patient display  14  is connected to the computer  12 , and is configured to visually convey a user interface for each of a plurality of different patients. According to the embodiment depicted in  FIG. 2 , the multi-patient display  14  is partitioned into sixteen distinct regions that are each adapted to visually convey a different user interface such that the technician  16  can generally simultaneously monitor sixteen different patients with a single display. It should, however, be appreciated that alternate multi-patient display configurations may be envisioned. 
         [0017]    Having described the operation of the centralized patient monitoring system  10  to assess patient health, the implementation of the multi-patient display  14  to visually convey such information will now be described in detail. Referring to  FIG. 2 , the multi-patient display  14  is shown in accordance with an embodiment. The multi-patient display  14  is configured to generally simultaneously display sixteen user interfaces  100 - 130  based on input from the computer  12 . According to one embodiment, each user interface comprises raw patient data (not shown) and a visual health status indicator (e.g., status indicators  132 - 138 ). The raw patient data is generally provided to enable a more detailed analysis of each patient. The visual health status indicator is configured to enable an observer to quickly assess patient health from a more remote location than would otherwise be possible. The following will describe several different visual health status indicator embodiments in more detail. 
         [0018]    The health status indicators  132 - 138  implement a color gradient adapted to convey patient health with a variable degree of color hue, saturation or intensity. For purposes of this disclosure, a color gradient should be defined as a spectrum or range of one or more colors. As an example, a red gradient may comprise a range extending from pure black (the complete absence of color) to bright red. Also for purposes of this disclosure, the term hue refers to a pure color (e.g., red, yellow, green, blue, etc.), the term saturation refers the level of color purity with respect to white, and the term intensity refers to the level of color purity with respect to black. 
         [0019]    It should be appreciated that each color gradient may comprise numerous visually distinct degrees of saturation or intensity such that a correspondingly large range of patient health assessments (e.g., including but not limited to good health, moderate health, poor health and critical health) can be visually conveyed. It should also be appreciated that the color gradient enables a technician to quickly identify the patients in need of immediate attention, and to do so from a greater distance than would otherwise be possible. 
         [0020]    For illustrative purposes, a more intense color is graphically depicted in  FIG. 2  with a greater degree of stipple density. Accordingly, the health status indicator  132  without any stippling represents the absence of color (i.e., black), and the health status indicator  134  with a minimal range of stippling density represents a minimal range of color intensity. Similarly, the health status indicator  136  with a moderate range of stippling density represents a moderate range of color intensity, and the health status indicator  138  with the widest range of stippling density represents the maximum range of color intensity. 
         [0021]    According to one embodiment, the color gradients may implement a single color hue to visually convey information pertaining to a given patient&#39;s health. As an example, the color gradients  132  may represent the absence of coloration in order to convey the fact that the monitored patients are in good health. Similarly, the color gradient  134  may represent a minimal color range from no intensity (i.e., black) to a red with very little intensity (i.e., dark red) adapted to convey moderate patient health. The color gradient  136  may represent a moderate color range from no intensity (i.e., black) to a mid range intensity red coloration adapted to convey poor patient health, and the color gradient  138  may represent the widest range of red coloration from no intensity (i.e., black) to high intensity red (i.e., bright red) adapted to convey critical patient health requiring immediate attention. 
         [0022]    According to another embodiment, the color gradients may implement multiple color hues in order to convey both a patient health assessment and the specific type of patient data on which the health assessment is based. As an example, the color gradients  132 - 138  may implement varying degrees of red saturation or intensity to convey a patient health assessment based on heard rate, and varying degrees of blue saturation or intensity to convey a patient health assessment based on blood pressure. 
         [0023]    Alternatively, the previously described color gradient may be replaced by or implemented in combination with other visual gradients such as a contrast gradient or an illumination gradient. As an example, a black and white display may implement a gray scale gradient with a variable degree of contrast or illumination to convey a patient health assessment. These alternative visual gradients may, for example, be implemented to ensure that colorblind technicians are able to readily and conveniently identify patient health. 
         [0024]    According to another embodiment, the health status indicators  132 - 138  implement a visual gradient adapted to convey patient health based on shape and/or relative size. As an example, the health status indicator  134  covering only a relatively small percentage of the user interface  102  may represent moderate patient health. Similarly, the health status indicator  136  covering an intermediate percentage of the user interface  112  may represent poor patient health, and the health status indicator  138  covering a relatively large percentage of the user interface  128  may represent critical patient health requiring immediate attention.
