This Pressure Valve is a spring-loaded valve that helps prevent the back flow of oxygen or water from a breathing tube back into a CPAP or BiPAP machine when the machine is turned off. Any back flow of oxygen or water passes out of the circuit through vents in the valve. When the CPAP machine is operating, the valve allows air to flow normally through the patient circuit; but when the pressure is eliminated the valve seals to prevent backflow.

Respironics recommends using this pressure valve whenever using oxygen with their CPAP machines. It is also compatible with CPAP units from ResMed, DeVilbiss, Covidien, Puritan Bennett and others. It can help protect the system from water back flow from the breathing tube or an external humidifier (which can cause permanent damage to the machine) and oxygen back flow (which can be a fire hazard).

The pressure valve should be attached inline between the machine and the primary breathing tube. This valve will not prevent water backflow from integrated humidifiers or humidifiers attached with a short coupler. This valve can be used in conjunction with Universal Inline Bacterial Viral filters. This valve may disable the auto-startup with breathing functions on some CPAP machines.
