connectors. Replace input hose or regulator if necessary.
5-
Slowly and fully turn on oxygen cylinder.
6-
Turn on ventilator and select child default setting.
7-
Press and hold manual button (E) and observe the pressure wave form
on the screen. If pressure drops immediately, inspect patient circuit
connections and ensure all connectors are attached. Use leak detector if
needed.
8-
Turn off the ventilator and pressure source.
Note
If leak is still present and no external leak was detected using the above
processes, the unit must be returned to the manufacturer or its authorised
service center for service or repair.
Function check
After confirming no leak is present in the ventilator, with the mains electrical

power. LED indicators should also switch to internal battery.
3-
Check battery level. Do not run the ventilator if battery level is low, install a
fully charged battery.
4-
During ventilator cycling, observe pressure wave and live ventilation
parameters on the screen.
5-
Disconnect the test lung and check for BCI (breathing circuit integrity)
visual alarm associated with yellow warning indicator. BCI audible alarm
associated with red warning indicator must activate in 15 seconds.
6-
Block patient output completely to activate Pmax alarm should be
activated.
7-
Re-connect the test lung, BCI visual and audible alarms should be de-
activated.
8-
Change Vt/Rate setting and observe changes on the lung, live ventilation
parameters, and the pressure wave form.
9-
Turn off PEEP and observe changes on the lung, live ventilation
parameters and the pressure wave form.
10-
Activate pause, night mode, and flow waveform to ensure proper
functions and screen display.
11-
Turn off oxygen cylinder and check for low pressure and no pressure
audible and visual alarms.
12-
