PROPRIETARY AND CONFIDENTIAL DRAFT 5 Feb 04

a. Set the Airway Pressure Relief control to the desired pressure limit according to the color-coded
bands on the Airway Pressure gauge and Airway Pressure Relief control.
b. Insert a “T” fitting with an airway pressure monitor into the Patient Outlet port, and connect it to
the Airway Pressure port to indicate the breathing circuit pressure. Adjust the Airway Pressure
Relief control as necessary.
4. Check the fixed internal Airway Pressure Relief Control by setting the desired Airway Pressure
Limit and blocking the exhalation valve port exhaust and the exhalation valve patient port. Observe
the Airway Pressure Gauge to check pressure limit.
NOTE:
The ability of the adjustable airway pressure relief valve to limit pressure is dependent on the flow rate of
gas. When an anesthesia-type bag is squeezed, the rate and depth of the compression affect the flow rate
through the valve. When the adjustable airway pressure relief valve is set under a constant flow condition
and the breathing bag is squeezed, the peak airway pressure may exceed that setting. To ensure that the
peak inspiratory pressure is set under more realistic conditions before use on an infant, adjust the airway
pressure relief while simulating normal bagging using a suitable test lung.
5. If a blender is installed, it flows through the Patient Outlet.
Auxiliary Flow
1. Connect the desired device to the Auxiliary Outlet connector.
2. Using the auxiliary Flow Rate control, adjust the desired auxiliary flow.
NOTE:
The Auxiliary Outlet oxygen percentage is not adjustable. It always supplies 100% oxygen.
