System and method of identifying patient interface device using mask cleaning system

A method of identifying a patient interface device to be used in a pressure support system using a mask cleaning system structured and configured to clean the patient interface device, the mask cleaning system having a controller, the method comprising:

• (a) operating the mask cleaning system during a cleaning period to clean the patient interface device;
• (b) obtaining in the controller one or both of the following:
• (i) a value for each of a number of operational parameters of the mask cleaning system for the cleaning period, and (ii) a sensor measurement for each of a number of sensors of the mask cleaning system for the cleaning period;
• and
• (c) determining an identity of or suspected change of the patient interface device in the controller by one or both of the following:
• (i) comparing the value for each of the number of operational parameters to operational parameter data stored by the controller, and (ii) comparing the sensor measurement for each of the number of sensors to sensor data stored by the controller.
