Self Check Fault - Pneumatic Sensor: Airway Pressure
Alarm triggers when the expiratory time is < 170 ms for 3 consecutive breaths.
When this occurs the device attempts to reestablish a baseline by momentarily
setting PEEP to 0 cm H
2
O and suspending triggered breaths. This interruption
lasts no longer than 2 breath cycles. The user should also check for leaks in the
hose and tubes, patient airway and exhalation valve. If recalibration is successful
the alarm will automatically cancel. If the device does not reset, manually
ventilated the patient, replace the ventilator and contact the service center for
additional information.
Mitigation/Info: Pneumatic Sensor: Airway Pressure, Check Circuit for
Leaks/Disconnects, Check Tube Placement/Cuff, **Contact Service
Center**
2062
Exhalation System Fault
Alarm triggers when the airway pressure, PIP, measured at the end of expiration
is > 5 cm H
2
O above the baseline pressure, PEEP. This is typically caused by a
restriction of the exhalation valve or an occlusion/kink in one or more of the
breathing circuit tubes or hose. If the breathing circuit tubes appear to be intact
the circuit should be replaced to eliminate the possibility of a bad exhalation
valve. If the condition does not resolve the user should manually ventilate the
patient, replace the ventilator and contact the service center for additional
information.
Mitigation/Info: Check Patient Exhalation, Check Circuit for Kinked Hose/
Tube, Check for Blocked Exhalation Valve, Replace Circuit, Replace/
Service Ventilator, **Manually Ventilate Patient**
2070
Airway Pressure High - Pressure Exceeds Limit Setting
Alarm triggers when the airway pressure, PIP, is > the high airway pressure limit
for 2 consecutive breaths. When the limit is reached, the flow decelerates to
keep the PIP below the airway pressure for the duration of the breath (inspiratory
time). The user should check for kinks or blockage of the breathing circuit,
exhalation valve or patient airway. In some instances the cause can be an
accumulation of secretions in the airway which will require suctioning to clear.
The user should also assess if the patient is fighting the ventilator, asynchrony, or
if the high airway pressure limit is set too low.
Mitigation/Info: Pressure Exceeds Limit Setting, Check Circuit for Kinked
Hose/Tube, Check for Airway Obstruction, Suction Airway if Necessary,
Check High PIP Limit Setting, ** Manually Ventilate Patient**
2071
Low Airway Pressure
Alarm triggers when the airway pressure, PIP, is < the low airway pressure limit
for 2 consecutive breaths. The user should check for leaks/disconnects in the
breathing circuit, patient airway or a failure of the exhalation valve. The user
should also assess if the patient is breathing with the ventilator, the PIP or tidal
volume are set too low, or if the low airway pressure limit is set too high. If a
replacement is available, the user should replace the breathing circuit. If these
mitigations do not resolve the alarm condition, replace the ventilator and contact
the service center for more information.
Mitigation/Info: Check Patient Connection, Check Circuit For Loose
Hose/Tube, Check Exhalation Valve, Check Tube Placement/Cuff,
Check Low Limit Setting, **Manually Ventilate Patient**
