O fl ow control valves. Verify that the
O
2
analyzer reads between 47-53%.
17. Set a fl ow of 6 L/min on the O
2
and N
2
O fl ow control valves . Verify that
the O
2
analyzer reads between 47-53%.
18. Close the O
2
and N
2
O fl ow control valves.
19. Set a fl ow of 3 L/min on the O

4.11.1 Pressure Build-up Test
1. Ensure that an O
2
supply is connected to the machine.
2. Ensure that the power switch is in the “OFF” position.
3. Ensure that all fl ow control valves are closed.
4. Connect a bulb and pressure gauge to the CGO taper.
If the machine is fi tted with an ACGO, ensure that the switch is set to
ACGO.
5. Turn the power switch to the “ON” position. Set of fl ow of 0.3 L/min on the
O
2
fl ow control valve.
6. Ensure that a pressure of 150 mmHg is reached within 7 seconds, then
turn the power switch to the “OFF” position.
