Product Details

Pressure Valve for CPAP Machines by Philips Respironics 

This Pressure Valve from Philips Respironics prevents water and/or oxygen back-flow into your CPAP machine from your tube or external/stand-alone humidifier. Air flows normally through the circuit when the CPAP/BiPAP machine is operating; when the machine is turned off, the valve prevents water (from an external humidifier) and oxygen (if using) from flowing back into the machine. Built-in vents in the pressure valve allows oxygen and water to exit the valve without flowing back into your device.

This pressure valve is compatible with any stand-alone humidifier and any CPAP and BiPAP machine without a built-in humidifier.

Note: This pressure valve does not prevent water back-flow when used with a CPAP/BiPAP machine with an integrated heated humidifier. 


Can I use this pressure valve on a CPAP machine with a built-in humidifier?

No, the pressure valve is not compatible with machines that come with an integrated heated humidifier.

Do I need to use a pressure valve if I use oxygen with my CPAP machine?

Using a pressure valve prevents oxygen from flowing back into and accumulating in your machine which can be a fire hazard.

Can you wash your Respironics Pressure Valve in water & soap like you do your hose face mask etc.

As per Philips, the valve should be cleaned weekly with mild detergent and warm water. Should the valve start to malfunction please replace the valve.

From a regulatory impact perspective, does the valve need to be included in any device testing such as biological testing for 510k purposes? If so, should it be tested with the CPAP machine or tested separately with the tubing?
