Table A-5 Low Priority Alarms
ALARM Possible causes Suggested action
Maximum rate
Low alarm limit. Leaks
in the patient circuit.
Check the alarm limit, and correct
it if necessary. In the case of ma-
jor leaks, high frequency auto-
triggering can be generated with
the configured alarm limit. In this
case, identify the possible areas
of leakage and repair them.
PEEP loss
Incorrectly configured
alarm limit. Leaks.
Faulty expiratory val-
ve diaphragm.
Review the alarm limits and iden-
tify the possible areas of leaka-
ge. Lastly, check the status of the
valve diaphragm. If necessary to
replace the diaphragm, use an
authentic one.
Nebulization OFF
Insufficient peak flow,
operate with nebuliza-
tion.
The nebulization is reset if the
peak flow is enough to be com -
patible with the nebulization.
Transporting
Lack of gas pressu-
re at the AIR inlet,
and activation of the
Transfer function. This
must be activated by
the user.
No corrective action is sugges-
ted. When the air supply is reset,
or when the user disables the
Transfer function, the alarm sig-
nals disappear.

Message Possible Causes Suggested Action
CO
2
no breathing
detected
Apnea condition Dis-
connected adapter of
the sensor, or of the
patient circuit. Dama-
ged or dirty adapter.
Check the capnograph adapter
connections. Clean if the win-
dows are very dirty.
CO
2
out of range
Measured value ex-
ceeds 150 mm Hg.
Perform a reset to zero.
Check the patient
adapter
Sensor out of the
adapter. Optical bloc-
king of the adapter
windows. Defective
reset to zero.
Check the presence of the sen-
sor in the adapter. Check that the
adapter windows are free of dirt.
In this case, clean the adapter,
allowing the sensor to release
any residual CO
2
from its interior,
and execute a new reset to zero.
Sensor failure Possible disconnection.
Check the sensor electrical con-
nection with the ventilator. If the
error persists, contact the autho-
rized technical service.
Sensor not acti-
vated
Poorly executed com-
pensation of barome-
tric pressure and gases
during the initial calibra-
tion of the ventilator.
Activate sensor, or save para-
meters from the capnography
menu.
Zero required
Problems with the
reset to zero of the
capnograph. Dirt, for
example.
Repeat reset to zero.
Sensor overheated
Sensor exposed to ex-
ternal heat sources.
Check presence of heat sources
within proximity of the sensor,
such as lamps or stoves. If the
message persists, contact the
authorized technical service.
