e. Set the ventilator controls to:
f. Select CMV again to begin ventilation.
g. Verify that the pressure waveform, Tidal Volume, Mean or Plateau Pressure, Resp.
rate and minute volume values appear on the screen.
h. Verify the Tidal Volume display is within 15% of the delivered volume measured with
the Vent Tester within approximately 1 minute from the start of ventilation.
i. Verify the delivered volume at the Vent Tester is within 15% of the Tidal Volume set
value within approximately 1 minute from the start of ventilation.
j. Verify the measured O
2
concentration is at least 97% after 5 minutes.
k. Set the AIR flow to 3 L/min and set the N
2
O and O
2
flow rates to minimum flow.
l. Verify the measured O
2
concentration is 21% ±3% vol. % after 5 minutes.
19. Verify that CMV CHILD ventilator mode operates and that the tidal
volume display reads within 10% of the CMV set value.
a. Attach a breathing circuit and breathing bag.
NOTE: For testing purposes always use a reusable breathing
circuit.
b. Attach an adult test lung to the Y-fitting 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 reduce
the Peak Pressure alarm limit to a lower valve to prevent
the alarm when using an adult test lung.
