A pressure support system for delivering a flow of breathing gas to a patient includes a pressure generating base unit including a gas flow generator and a controller, a patient interface device for delivering the flow of breathing gas to the airway of the patient, and a degradation monitor apparatus including a control unit and an indicator apparatus. The controller is structured to generate data indicative of a degradation metric based on use of the pressure support system and to communicate the data indicative of the degradation metric to the degradation monitor apparatus. The control unit of the degradation monitor apparatus is structured to cause the indicator apparatus to generate a human perceptible indication based on the data indicative of the degradation metric when the degradation metric indicates that a component of the patient interface device demonstrates at least a threshold level of degradation.
