Abstract
Official abstract text for this publication.
A vent valve apparatus ( 10 ) for use with a system for supplying breathable gas pressurized 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 2 gas through the washout vent ( 15 ) over a range of gas supply pressures.
First claim
Opening claim text (preview).
I claim: 1. A method for supplying pressurized breathable gas to a patient with a CPAP apparatus including a flow generator structured to generate a supply of pressurized gas, a mask adapted to provide a seal with the patient's face, and a conduit that interconnects the flow generator and the mask, the method comprising: generating a supply of pressurized gas with the flow generator; sealing the patient's face with the mask; interconnecting the flow generator and the mask with…
