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.
FAQCan 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.
