7. Start ventilation.
8. Verify that the pressure waveform, respiratory volume, mean or plateau pressure, respiratory
rate, and minute ventilation appear on the screen.
9. Verify that the tidal volume displayed on the anesthesia machine is within 7% (±42 mL) of
the value displayed on the ventilation tester within approximately the first 1 minute after
ventilation starts.
10. Verify that the tidal volume displayed on the anesthesia machine is within 7% (±42 mL) of
the setting within approximately the first 1 minute after ventilation starts.
5.14.3 VCV Pediatric Ventilation Mode Test
1. Attach a breathing circuit and a manual bag.
NOTE
 For testing purposes, always use a reusable breathing circuit.
2. Attach an adult test lung to the Y-piece of the breathing circuit.
NOTE
 Limit the volume in the test lung to provide sufficient airway pressure to satisfy the
Low Peak Pressure alarm. Or set the peak pressure alarm limit to a smaller value
to prevent the alarm when an adult test lung is used.
3. Connect a ventilation tester between the expiratory port and the breathing hose.
4. Set the O2 flow to 2 L/min and set the N2O and air flows to the minimum value.
5. Set breathing parameters.
