1. A respiratory device comprising
a blower having an inlet and an outlet,
a patient interface,
a valve coupled to the blower and operable to control a pressure applied to the patient interface,
a sensor to sense at least one of pressure and flow applied to the patient interface, and
a control circuitry coupled to the blower, the valve, and the sensor, the control circuitry operating the blower and the valve to apply a first threshold pressure to the patient interface for a first preset amount of time in response to an inspiratory trigger being sensed by the sensor, the control circuitry operating the blower and the valve to apply a second threshold pressure to the patient interface during a rest phase that occurs after the first preset amount of time, the control circuitry operating to ignore one or more inspiratory triggers that are sensed by the sensor and that occur during the rest phase.
