This spring loaded valve by Philips Respironics that efficiently prevents back flow of water or oxygen from a breathing tube into the BiPAP or CPAP machine when the machine is turned off. While CPAP machine is functioning, the valve permits air flow through the patient circuit. However, as the pressure stops, the valve is designed to be sealed to prevent any backflow.
Philips Respironics recommends using this BiPAP or CPAP Inline Pressure Valve always while using oxygen with the machines as it effectively prevents oxygen or water back flow into an external humidifier or the breathing tube. The valve is compatible with all CPAP units from DeVilbiss, Covidian, ResMed, Puritan Benett and others.
Generally, the inline pressure valve is attached inline between the primary breathing tube and the machine. The blue edge of the valve faces towards the machine and equips a 22 mm connector.
Please Note: This valve does not prevent water backflow from integrated humidifiers or the humidifiers that are attached with a short coupler.
