A gas washout vent, and a patient interface with the gas washout vent, configured to allow patient-exhaled COto flow to an exterior of the plenum chamber to minimise rebreathing of exhaled COby the patient, the gas washout vent including at least one outlet orifice; a diffusing member at least partly covering the outlet orifice; and a blocking member having an air-impermeable material, the blocking member preventing gas exiting from the outlet orifice from flowing straight through the diffusing member.
