Respironics Pressure Valve for Oxygen Concentrator Users

This pressure valve helps to prevent oxygen or water from a breathing tube or external humidifier (which can cause potential damage to the machine) back to flow back into a CPAP or BiPAP machine. Any backflow of oxygen will or water passes out of the circuit through the vents in the valve, when the machine is turned off. The valve lets air to pass through the patient circuit when the CPAP machine is operating. It is compatible with any CPAP or BiPAP machine minus a humidifier. The pressure valve should be attached inline between the machine and the primary breathing tube. It is easy to apply.
