Check-out Procedure

The unit should be checked for proper operation before each use. This can be done
after cleaning to prepare the unit for the next use.
Set the ventilator to the following settings:
 BPM = 10
 Tidal Volume = 640
 Inspiratory Time = 2 seconds
General Operation Check:
1. Connect a 50 psi oxygen source to the unit and turn the power on. The unit
should begin to cycle.
2. Using a stop watch, count the number of breaths delivered in 1 minute
(60 seconds).
 Confirm that between 9 and 11 breaths have been delivered.
 Confirm that the inspiratory time is significantly shorter than the expiratory
time. (At the settings noted above, the ventilator should provide a 2.0 second
inspiratory time and a 4.0 second expiratory time.)
3.
Connect the 22 mm corrugated tubing or the allied patient circuit provided, to
the patient circuit connection port. (See Item 9 Under Features On Page 4).
Block the patient end of the corrugated tubing.
 Confirm that the airway pressure does not exceed 60 cm H
the airway pressure display on the face of the ventilator.
 An alarm will sound at approximately 45 cm H
4. Visually inspect the anti-suffocation valve in the patient circuit connection port to
verify that the valve is flush to the contour of the round inner surface and that no
gap exists.
Alarm Mode Check:
1. Low source gas:
 Reduce the source gas pressure to below 35 psi and monitor that the red
LED display turns on and an audible alarm sounds. Return the source gas
pressure to 50 psi, and the alarm should clear in 15 seconds.
2. High airway pressure:
 Block the patient circuit connection port, and monitor the red LED display for
high airway pressure, and an audible alarm will sound. The mechanical
pressure relief should limit the airway pressure to less than 60 cm H
3. Breath delivery:
 Clear the patient circuit connection port and allow the ventilator to cycle for at
least 20 seconds. The airway pressure display should not exceed 9 cm H
for 15 seconds. Monitor that the red LED is flashing on the breath delivery
failure alarm, and an audible alarm will sound.
Should the unit fail any of these tests, contact Allied Healthcare Products, Inc.,
Technical Support Center in St. Louis: 314-771-2400 or 800-411-5136.
