Abstract:     A vent valve apparatus ( 10 ) for use with a system for supplying breathable gas pressurised above atmospheric pressure to a human or animal. The apparatus ( 10 ) includes a gas washout vent ( 15 ), a vent valve ( 18 ) adapted to progressively restrict the flow area of the washout vent ( 15 ), and a pressure sensitive vent valve control means ( 20,22,23 ). The control means is adapted to progressively cause the vent valve ( 18 ) to restrict the flow area of the gas washout vent ( 15 ) in response to increases in the pressure of the gas supply, thereby substantially regulating the volumetric flow of gas and/or CO<SUB>2 </SUB>gas through the washout vent ( 15 ) over a range of gas supply pressures.
