5 Performance check (Leak & Function test):
To undertake the performance check, you will need the following:
Full Oxygen cylinder.
Calibrated test lung (Provided with the unit).
Oxygen pressure regulator capable of delivering flow of 120 L/min and
maintaining a minimum pressure of 45 PSI (3 Bar) and a maximum 87
PSI (6 Bar) output pressure.
a- Connect Input hose to input connector (T) and the other side of input
hose to pressure regulator outlet.
b- Connect power supply to DC input socket.
c- Connect the 2 sensor hoses of patient circuit to sensor connectors #1 (Q)
and #2 (R) and connect the corrugated hose of patient circuit to output
connector (S) (Refer to Figure 2).
d- Once the ventilator is started, connect the other end of patient circuit to
test lung.
Leak Test
Once all connections are verified, slowly and fully turn on the oxygen cylinder
valve. From the pressure regulator gauge reading, ensure cylinder pressure is
above 650 PSI (45 bar) otherwise replace with new oxygen cylinder.
Once pressurized, turn off the oxygen cylinder and observe the pressure
regulator gauge reading. If pressure does not drop more than 0.5 PSI every 30
seconds, the system is free from leaks.
To identify and repair the leak:
1- Release the remaining gas from the system.
2- Tighten all connecters firmly.
3- Slowly and fully turn on oxygen cylinder and repeat the above leak test
procedure.
4- If leak still present, spray oxygen compatible leak detector on hose and
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.
