b. Insert a “T” fitting with an airway pressure monitor into the Patient Outlet port. Connect it to the
Airway Pressure port to indicate the breathing circuit pressure. Adjust the Airway Pressure
Relief control as necessary.
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.
4. If a blender is installed, it flows through the Patient Outlets.
Patient Flow 2
1. Connect the desired device to the Patient Outlet 2 connector.
2. Using the Flow Rate 2 control, adjust the desired patient flow 2.
