14.2 Pneumatic set up
a) Connect the ventilator to gas supplies at 4 bar.
b) Set the air and oxygen input pressure regulators PR1 and PR2 to 40 psi ± 0.1
psi.
c) Set the oxygen regulator to 40 psi ± 0.1 psi. Tighten the tension nut to lock the
spindle in position ensure that the pressure is still within 0.1 psi of 40. (The
oxygen regulator will not be adjusted again). Set the other regulator to match
the first setting within 0.1 psi.
d) Turn on the ventilator. Fully close FR7, fully open FR8, then, with the fresh gas
valve SV7 energised, monitor the flow from the fresh gas outlet port on the
front panel, and adjust PR5 to provide about 10LPM (±0.5LPM).
e) Electrically disconnect the forward and mean jets so they are completely
closed off, then, with a full patient circuit connected and ET connector
occluded, adjust FR8 to achieve 0.25 mbar ± 0.05mbar at the ET connector
(SV7 Energised) and lock. (Reconnect forward and mean jets)
Check list Item 5
f) Monitoring the flow from the fresh gas port again re adjust PR5 to obtain a flow
of 8LPM ± 0.25LPM and lock, re-check zero level is as step e.
Check list Item 6
g) With the fresh gas valve SV7 de-energised, ensure the flow at the fresh gas
port is at least 1.2LPM (typ. 1.8LPM).
Check list Item 7
h) Occlude the fresh gas supply with SV7 de-energised and ensure that the
pressure developed in the fresh gas limb is between 10 and 20 mbar.
Check list Item 8
i) With SV7 energised, ensure that the fresh gas pressure relief valve is
activated at greater than 160 mbar and no more than 170 mbar.
Check list Item 9
j) Turn on the ventiltator. Tee into the output of PR5 and check that the pressure
is 22PSI ± 2PSI.
Check list Item 10
k) Adjust FR7 to obtain a purge flow of 0.2LPM±0.05LPM and lock.
Check list Item 11
l) Check that the exhaust oxygen from the relief port on the oxygen Watson
Smith regulator (N6615/02) is not greater than 1.5 lpm.
m) Check for leaks in the pneumatic system.
