Zusammenfassung:	A system including methods and apparatus for treatment of a medical disorder such as obstructive sleep apnea or congestive heart failure. The system includes a gas flow generator and a patient interface. The system delivers a flow of gas to the patient using the gas flow generator and the patient interface. The system determines that the patient is experiencing an apnea and, in response, performs a pressure change maneuver. This maneuver includes increasing a pressure of the flow of gas for a period of time, and decreasing the pressure of the flow of gas after the pressure increase. The system then monitors the change in flow rate for the flow of gas resulting from the pressure change maneuver, if any, and determines whether the airway of the patient is open or closed based on the monitored change in the flow rate.
