Alarm Message
Possible Cause
Corrective Action
- If Ftrig is used, ensure that
exhalation flow sensor is faultless
and calibrated.
Apnea
No breath has been delivered in set
mode (no patient triggered breath or
delivered breath by the ventilator)
- Check the patient condition.
- Check the device settings
(especially ventilation mode and
trigger value)
- Check the alarm limits.
- If Ftrig is used, ensure that
exhalation flow sensor is faultless
and calibrated.
High Leak
Leak value has exceeded alarm limit.
- Check the patient airway.
- Check the alarm limits.
- Ensure that exhalation flow
sensor is faultless and calibrated.
- If the alarm persists, contact the
Customer Service department.
Plim Reached
In volume based modes and during
inhalation if the airway pressure
exceeds“ high Ppeak alarm -5”
- Check the patient airway.
- Check the device settings.
- Check the pewssure alarm range.
High Oxygen
The oxygen concentration is too high
compared with high alarm setting.
- Ensure that the oxygen sensor is
faultless and calibrated.
- Check the air and oxygen
sources.
Low Oxygen
The oxygen concentration is too low
compared with low alarm setting.
- Ensure that the oxygen sensor is
faultless and calibrated.
- Check the oxygen source.
- Check the inlet pressure oxygen
source concentration.
Volume Not
Delivered
The set volume has not been delivered
to the patient (in one of PRVC-CMV,
PRVC-SIMV or VSV modes that the
pressure is determined by the device).
- Check the device settings.
- Check the alarm limits (high limit
of Ppeak).
Disconnection
The breathing circuit from the
ventilator to the patient is disconnected.
- Check the patient airway.
Occlusion
The breathing circuit or expiration
valve has been occluded.
- Check the patient condition.
- Check the patient airway.
- Check expiration valve.
High O2 Pressure
The oxygen inlet pressure is more than
the specified level.
- Check the oxygen source.
- If the alarm persists, contact the
Customer Service department.
Low O2 Pressure
The oxygen inlet pressure is lower
than the specified level.
This alarm will not be enabled if the
oxygen concentration is set to 21%.
- Check the oxygen source.
- If the alarm persists, contact the
Customer Service department.
High Air Pressure
The air inlet pressure is more than the
specified level.
- Check the air source.
- If the alarm persists, contact the
Customer Service department.
