Leakages; Possible Leakage Causes - Dräger Perseus A500 Instructions For Use Manual

Troubleshooting

Leakages

Leakages may result in the system not being
operational or being operational with limitations
only.
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.
Before using the device, perform the leakage test
to check the leak-tightness of all the valves.
WARNING
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.
