Locating and remedying leakages
Leakages can lead to a failure of the system test or
the leakage test and must be remedied.
Possible causes of leakage
– The CO
2
absorber or the CLIC adapter is not
securely screwed to the breathing system.
– The APL valve is not correctly fitted to the
breathing system or is not set to 30 hPa
(cmH
2
O).
– The breathing bag, the breathing hoses, the Y-
piece, or the microbial filter is incorrectly fitted
or damaged.
– The holder for the breathing bag is incorrectly
mounted to the breathing system. The sealing
ring is soiled or damaged.
– The water trap is not connected.
– The sample line is not connected, is kinked, or
is leaking.
– The connections for the sample line are
damaged.
– The O-rings on the inspiratory port or
expiratory port are damaged, soiled, or
missing.
– The flow sensor is incorrectly installed or
damaged. The rear O-ring is missing.
– The valves or seals of the breathing system are
damaged.
– The cone for occluding the Y-piece is scratched
or damaged.
– The filling or emptying connections on the
vaporizer are leaking or are open. The
vaporizer is incorrectly fitted. The O-ring is
missing or damaged. The control dial is not in
the 0 position.
CAUTION
Risk due to contamination
Anesthetic gas can get into the ambient air as a
result of leakages.
– Perform the leakage test before using the
device.
– Remedy all leakages.
CAUTION
Risk due to leakage at the valves
Leakages at valves can allow ambient air to enter
the breathing system and alter the composition of
the breathing gas.
– Perform the leakage test before using the
device.
– Check all valves for leakage.
CAUTION
Risk of insufficient ventilation
Breathing gas may escape because of leakages,
with the result that the applied volume is less
than the set volume.
– Perform the leakage test before using the
device.
– Remedy all leakages.
