A pressure support system and method of using same that includes a pressure generator adapted to provide a gas flow, a conduit coupled to the pressure generator to deliver a gas flow to a patient, an interface device coupled to the conduit to communicate the gas flow to an airway of the patient. An exhaust vent that provides a flow of exhaust gas to atmosphere is provided in the conduit or the interface device. A flow sensor detects a rate at which gas flows in the conduit and provides a first output indicative thereof, and a pressure sensor detects a pressure of gas at the patient and provides a second output indicative thereof. A control system receives the first and second outputs and determines whether a current flow of exhaust gas passing through the exhaust vent is below an alarm threshold based on the first and second outputs and provides a third output indicative of this determination.
