(57) ABSTRACT
There is provided herein an electronic patient monitor that utilizes a latch or similar power circuit that automatically activates an electronic patient monitor when a patient's presence is indicated by the sensor, that maintains power to the unit so long as the patient is indicated to be present, and that maintains power to the monitor until a valid reset command is issued after the patient is sensed to be no longer present. Power to the unit is maintained, and the unit continues to monitor the patient, e so long as the patient is present, even if an attempt is made to power down/disable the unit during that time.
