9. Check calibration of Inspiratory Pressure control (continued)
xi) Disconnect one limb of the Patient Circuit.
xii) After 8 seconds the ‘low inflation pressure’ alarm should flash and sound. The LED should
flash 30 times a minute and the medium priority audible alarm should sound.
xiii) Select ‘0’.
xiv) Turn off and disconnect the air supply.
xv) Disconnect Patient Circuit, Test Lung and pressure gauge from the
ventilator.
10. Check calibration of Oxygen Concentration control on CMV with oxygen supply only
(refer to Figure 8)
i) Fit a 22mm hose at least 300mm long, a Backpressure Device (500-A82803) and an Oxygen
Monitor (POM 602) onto the output connector of the Control Module.
ii) Connect a 22mm hose, at least 900mm long, to the outlet of the Oxygen Monitor to ensure
that atmospheric air cannot reach the sensor during the expiratory phase
iii) Select CMV + PEEP. Both the ‘single gas operation’ LED and the ‘cycle’ LED should
indicate.
iv) Set a backpressure of 20 x100Pa (20 cmH
2
O) using the Backpressure Device.
v) Set T
INS
to 2.0 seconds and T
EXP
to 4.0 seconds.
vi) Record the actual oxygen concentrations at the various settings indicated by section 15 of the
Service Record Sheet.
vii) Set T
INS
to 0.25 seconds and T
EXP
to 0.25 seconds.
viii) Repeat vi) above.

11. Check calibration of Oxygen Concentration control on CPAP with oxygen and air supply
(refer to Figure 8)
i) Reconnect and turn on the air supply.
ii) Select CPAP. There should be no audible or visual electronic alarms.
iii) Set a backpressure of 20 x100Pa (20 cmH
2
O) using the Backpressure Device.
iv) Check and record oxygen concentrations at the various settings indicated by section 16 of
Service Record Sheet.
v) Select ‘O’. Turn off and disconnect the air supply.
vi) Remove the Oxygen Monitor and 900mm hose.
