Yearly Verification of function and Calibration:
Equipment Required
 Certified gas flow analyzer, capable of measuring BPM, inspiratory time and
tidal volume
 Regulated 50 psi oxygen source
 New batteries
 36 inches of 22 mm corrugated tubing or the allied patient circuit provided.
Procedure
 Connect the 50 psi oxygen source to the oxygen inlet connector.
 Connect the 22 mm corrugated tubing to the patient circuit connection valve, and
the other end to the gas analyzer.
 Turn the tidal volume, inspiratory time and BPM to the values indicated in the
table below. Monitor the values to evaluate acceptability of the unit.

 To test pressure relief, turn tidal volume to 640 ml, block the patient end of the
22 mm corrugated tubing or patient circuit while monitoring the airway
pressure display. The airway pressure should not exceed 60 cm H
High Airway Pressure alarm should sound and a red LED should be activated.
 To test the breath delivery failure alarm, remove all obstructions from the patient
circuit connection valve and allow the ventilator to cycle. The breath delivery
alarm should sound, and a red LED should be flashing.
 To test the low source gas alarm, reduce the inlet pressure source to below
35 psi. The low source gas alarm should sound and a red LED should be
flashing.
Should the unit fail any of these tests, contact the Allied Healthcare Products, Inc.,
Technical Support Center in St. Louis: 314-771-2400 or 800-411-5136.
