Adult APL Valve Circuits
The Venticaire Adjustable Pressure Limiting valve is of a variable orifice design. The unique design of the Venticaire valve allows adjustment of the escape of expiratory and excess fresh gas as required in order to maintain a constant pressure in the breathing system. As soon as the pressure inside the breathing system increases above 60cm H2O in the adult valve, and 35cm H2O in the paediatric valve, the stem of the valve is pushed up, allowing spillage of excess gas. As soon as the pressure drops below the values mentioned above, the spring will push the stem back to it's pre-set position. This will maintain the pressure within the breathing system at a constant level.

The simple mechanism of the Venticaire Adjustable Pressure Limiting valve produces a linear performance and protects against over inflation of the reservoir bag. This permits a minimal resistance to expiration so preventing pneumothorax or trauma to the airways.
Valve Function
The function of the APL valve is to allow expired and excess fresh gas to escape (spill) from a breathing system without allowing entry of the outside air into the breathing system even during inspiration.

PRODUCT CODE
Venticaire APL Valve
To set the valve initially, test the valve in the open position to check for flow and then test the valve in the closed position to ensure correct function. In use, depending on the fresh gas flow and the type of breathing system, you adjust the valve by turning the cap to a position that permits the rebreathing bag to inflate and deflate with breathing, without allowing over inflation or collapse of the reservoir bag.
