Abstract
A failsafe supervisor system for a patient monitor which integrates the functions of coordinating the turning on/off of the patient monitor with the user and the system software, alerting the operator in the event the patient monitor turns off due to a power failure, and alerting the operator to improper operation of the patient monitor system's processor hardware or software. Upon detection of such unexpected changes of state or malfunctions during operation of the patient monitor, the patient monitor is powered down in a failsafe manner to a safe state. Additionally, the failsafe supervisor system optionally allows the operator to select a service mode when turning on the monitor, thereby facilitating testing. The entire failsafe supervisor system is preferably implemented in a small one-chip microcontroller so that it can be readily incorporated into the patient monitor's microprocessor control system.
