Troubleshooting
!! 150 Emergency air inlet acti-
vated
There was not enough gas to
ventilate the patient. To main-
tain a minimum ventilation,
the device has started to use
ambient air.
Refill the breathing bag, e.g.,
with O
2 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.
!! 135 etCO
2 high etCO2 has exceeded the
upper alarm limit.
Check ventilation.
!! 135 etCO
2 low etCO2 is below the lower
alarm limit.
Check ventilation.
!! 100 Exp. pressure sensor fail-
ure
Sensor calibration failed. Ensure that a suitable substi-
tute monitoring is available.
Perform the system test.
If the problem persists, call
Dräger.
! 100 Expiratory flow sensor
expired
Accessory has been used
too long.
Replace the accessory if nec-
essary.
Use "ALARM RESET" to
acknowledge alarm.
! 255 Expiratory flow sensor
failure
The sensor is not calibrated.
The breathing system has
been replaced or discon-
nected since last calibration.
Perform the leakage test.
Failure of the flow sensor. Replace the flow sensor and
perform a leakage test.
!!! 200 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.
