exhalation valve. See Detail A, Figure 5–1.
• For use with an HME, attach the Proximal Pressure line
to a pressure tee adapter (p/n NP130-22) on the patient
side of the HME. Use the cap that comes with the tee
adapter to seal the pressure port on the exhalation
valve. See Figure 5–5.
• For use with a humidifier, attach the Proximal Pressure
line to a pressure tee adapter (p/n NP130-22) before
the inlet port on the humidifier. Use the cap that
comes with the tee adapter to seal the pressure port
on the exhalation valve. See Figure 5–4.

Exhalation Valve Calibration 6. Calibrate the exhalation valve prior to use as follows:
WARNING Each time an exhalation valve is replaced or
maintained it must be calibrated.

ventilator as instructed above. Connect an adult (500 mL)
test lung with restrictor (LNG500A) or occlude the patient
connection of the breathing circuit.
b. Press the On/Standby button once to enter Settings
condition.
c. Press the Manual Inflation button once, then again within
