Output Leak Test
1. Open the cylinder valve slowly, at least two full turns, counter
clockwise.
2. Turn on ventilator and select child default setting.
3. Press and hold manual key (E) (Figure 01) and observe the
pressure wave form on the screen. If pressure drops immediately,
inspect patient circuit connections and ensure all connectors
are attached. If the leak is still present replace the circuit and
repeat from 1. To confi rm correction of the leak.
Input Leak Test
Once all connections are verifi ed, open the cylinder valve slowly, at
least two full turns, counter clockwise. From the pressure regulator
gauge reading, ensure the cylinder pressure is above 650 PSI (45
bar) otherwise replace with new oxygen cylinder.
Once pressurized, turn off the oxygen cylinder and observe the
output pressure on the gauge of the regulator. Note that to perform
this test, a regulator with cylinder and output pressure readings
are needed. If pressure does not drop more than 0.5 PSI every 30
seconds, the system is free from leaks.
To identify and repair the input leak:
1. Release the remaining gas from the system.
2. Tighten all connecters fi rmly.
3. Open the cylinder valve slowly, at least two full turns, counter
clockwise.
4. If leak still present, spray oxygen compatible leak detector on
hose and connectors. Turn off the regulator and replace the
input hose or regulator if necessary. Repeat from 1. to confi rm
correction of the leak.
