1. A method of delivering pressurized gas to an airway of a patient, comprising the steps of:

  • providing a gas flow generator and a patient interface adapted to couple the gas flow generator to an airway of a patient;

    delivering a flow of gas to such a patient using the gas flow generator and the patient interface;

    determining that the patient is experiencing an apnea;

    performing a pressure change maneuver responsive to determining that the patient is experiencing the apnea, wherein the pressure change 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;

    monitoring a change in flow rate for the flow of gas resulting from the pressure change maneuver; and

    determining whether the airway of the patient is open or closed based on the monitored change in the flow rate.
