Maintenance systems and methods for medical devices

A method of automatically initiating the execution of one or more maintenance tasks for a flow generator and a humidifier of a medical device, the medical device comprising a system health protection component configured to respond to an unexpected condition, wherein the system health protection component comprises a transient current detector and a thermal cutout and the one or more maintenance tasks comprise a functional check including validating an operation of the system health protection component of the medical device, the method comprising executing the one or more maintenance tasks by:

• generating or simulating, by a processor, an unexpected condition, the unexpected condition comprising a transient current, an overcurrent, or supplying power to a heating element of the medical device;
• providing, by the processor, a signal associated with the unexpected condition to the system health protection component;
• determining, by the processor, a response of the system health protection component to the unexpected condition by measuring an electrical value in the system health protection component and the heating element of the medical device, the medical device comprising the flow generator and the humidifier;
• and
• based at least in part on the response, providing, by the processor, a result that the system health protection component does not successfully recognize the unexpected condition, incorrectly identifies the unexpected condition, or is too slow to recognize the unexpected condition,
• wherein the method further comprises using hardware and software of the medical device to generate or simulate the unexpected condition to test both hardware and software responses of the system health protection component.
