tain a minimum ventilation,
the device has started to use
ambient air.
Refill the breathing bag, e.g.,
with O

flush.
Increase fresh-gas flow.
Check the breathing circuit
for tight connections and
leakages.
An external anesthetic gas
monitor is extracting gas
from the breathing system
via a sample line.
Disconnect the sample line.
Seal the sample line port.

External fresh-gas outlet
failure?
The internal fresh-gas valve
is faulty. It is unclear whether
the fresh gas is being fed into
the internal breathing sys-
tem or towards the external
fresh-gas outlet.
Use "O
2
+" button to deter-
mine flow direction of fresh
gas: -If internal breathing
system or breathing bag fill,
external fresh-gas outlet is
not available. -If gas flows
out of the external fresh-gas
outlet, external fresh-gas out-
let can be used. Internal
breathing system can only be
used when the breathing bag
is not connected (ventilation
with ambient air only).
Check fresh-gas settings.
If the problem persists, call
Dräger.
