Abstract: An apparatus for automated control of gas washout of a patient interface of a respiratory treatment apparatus comprising: a vent assembly having a variable size exhaust area defined by one or more overlapping apertures (90, 95), wherein in use the vent assembly vents expiratory gas from the patient interface; and an actuator to manipulate said one or more overlapping apertures of the vent assembly. The variable size exhaust area is configured to be set to a plurality of open positions, the plurality of open positions providing different opening area sizes for venting expiratory gas from the patient interface.
