A respiratory device includes a pressure source to produce pressure to be applied to a patient's airway, a housing that contains the pressure source, an outlet port that is accessible on the housing, a valve that is be situated pneumatically between the pressure source and the outlet port, and at least one pressure sensor and at least one flow sensor to measure pressure and flow, respectively, in a flow path that is between the valve and the outlet port. The respiratory device includes a patient interface that has a tube having a first end that is coupled to the outlet port and a mask that is coupled to a second end of the tube. The respiratory device also includes a controller that receives signals from the pressure sensor and the flow sensor to determine an inspiratory trigger indicative that the patient has started to inhale. The pressure source or the valve or both are operationally adjusted in response to detection of the inspiratory trigger. Based on a flow sensor signal from the flow sensor the controller is configured to determine mask removal or mask leakage and to stop operation of the pressure source.
