A system, comprising: a patient support unit having a patient environment; a heating module comprising a heater (25, 30, 35, 40) and a heating module controller (05, 115, 125) operatively coupled to the heater (25, 30, 35), wherein the heater is configured to warm the patient environment; a sensor module comprising one or more sensors (65, 70, 75 100) and one or more controllers (80, 50, 55, 105) operatively coupled to the one or more sensors (65, 70, 75, 100) and to the heating module, wherein the one or more sensors (65, 70, 75, 100) are configured to measure patient-specific data of a patient in the patient environment; and a control system comprising at least one processor, at least one memory coupled to the at least one processor and including at least one program stored thereon, and at least one input interface, wherein the control system is configured to selectively operate the system in a pre-programmed cooling mode configured to disable the heating module while monitoring the patient-specific data of the patient using the sensor module, characterized in that the heating module further comprises one or more heater-related alarms configured to sound when a sensed heater condition falls outside of a programmed range, wherein the heater-related alarms are automatically disabled by the control system when the system is selected to operate in the cooling mode, wherein the sensor module further comprises one or more patient-related alarms configured to sound when a sensed patient-condition falls outside of a programmed range, and wherein the patient-related alarms are maintained by the control system when the system is selected to operate in the cooling mode. a patient support unit having a patient environment; a heating module comprising a heater (25, 30, 35, 40) and a heating module controller (05, 115, 125) operatively coupled to the heater (25, 30, 35), wherein the heater is configured to warm the patient environment; a sensor module comprising one or more sensors (65, 70, 75 100) and one or more controllers (80, 50, 55, 105) operatively coupled to the one or more sensors (65, 70, 75, 100) and to the heating module, wherein the one or more sensors (65, 70, 75, 100) are configured to measure patient-specific data of a patient in the patient environment; and a control system comprising at least one processor, at least one memory coupled to the at least one processor and including at least one program stored thereon, and at least one input interface, wherein the control system is configured to selectively operate the system in a pre-programmed cooling mode configured to disable the heating module while monitoring the patient-specific data of the patient using the sensor module, characterized in that the heating module further comprises one or more heater-related alarms configured to sound when a sensed heater condition falls outside of a programmed range, wherein the heater-related alarms are automatically disabled by the control system when the system is selected to operate in the cooling mode, wherein the sensor module further comprises one or more patient-related alarms configured to sound when a sensed patient-condition falls outside of a programmed range, and wherein the patient-related alarms are maintained by the control system when the system is selected to operate in the cooling mode.
