Safety Regulator
1 While still in Diagnostics Mode “d3”, adjust Flow to 3 L/min.
2 Connect a patient circuit to the e360 ventilator as shown in
Figure 6-1. (Test lung is not needed)
3 Disconnect the patient circuit from the Exhalation V
alve, and
connect it to the Y-piece of the patient circuit, which is to form
a close loop.
4 Tee in a low pressure gauge in the patient circuit.
5 Use a flat head screw driver to adjust the Safety Regulator,
see Figure 5-4, to obtain 140 ± 5 cm2HO of “
Machine 1”
pressure displayed on LCD touch screen.
6 Verify the reading of the pressure gauge is within 2 cmH
2
O of
the value of “Machine 1” pressure.
7 Adjust Flow to 0 L/min after the calibration is completed. Then
press “
Manual Inflation” button to disable manual flow
adjustment.
The “
Message ID” will change to “13”.
