4.8.3 Air Pipeline Test
NOTE: Different from the O
2
pipeline supply, when the air pipeline supply is
disconnected, no alarms related to Air pressure occur as Air pressure
decreases.
1. Connect the Air pipeline supply.
2. Close all cylinder valves if the A5/A3 anesthesia machine is equipped with cylinders.
3. Set the system switch to the ON position.
4. Set the flow controls approximately to mid-range (approximately 6 L/min).
5. Check that the Air pipeline pressure gauges show 280 to 600 kPa (40 to 87 psi).
6. Disconnect the Air pipeline supply.
7. Ensure that the Air gauge decreases to zero.
4.9 Basic Ventilation Testing
a. Attach a breathing circuit and breathing bag.
b. Attach an adult test lung or breathing bag to the patient end of the Y-fitting of the
breathing circuit.
c. Set the O
2
flow to 3 L/min and set the N
2
O and AIR flow rates to zero flow.
d. Set the ventilator controls to:
e. Select PCV and begin ventilation.
f. Verify that the breathing bag at the patient end of the Y-fitting of the breathing circuit
inflates and deflates and that the PLAT on the display and the PAW gauge are consistent
with the Ptarget setting.
