2090 PEEP Leak
Alarm triggers when the airway pressure drops below the PEEP setting by 2 cm H
phase of the breath. This can be caused by a leak in the breathing circuit, exhalation valve or patient airway.
The user should check the breathing circuit and exhalation valve to ensure that all connections are tight. If the
circuit appears damaged or is suspect it should be replaced. The user should also check if there is a cuff leak
from the patient's airway or mask. If these mitigations do not resolve the alarm the user can choose to use
leak compensation to provide additional flow during the expiratory phase to compensate for the leak. If you
still cannot compensate for the leak, consult the attending physician. If this fails replace the ventilator and
contact the service center for more information.
2095 Insufficient Flow
Alarm triggers when the pressure target is not reached during the inspiratory period during pressure targeted
ventilation. Typically this can occur when the Rise Time is set too low for the patient and their respiratory
mechanics. Decrease the Rise Time and check the circuit and exhalation valve for leaks or disconnects. If
the flow cannot be adjusted appropriately then the patient should be ventilated using volume targeted ventila-
tion.
Mitigation/Info: Pressure Target Not Met, Decrease Rise Time , Press/Hold BPM Button, Consult Physician,
** Ventilate With Volume Target**
2100 Patient Disconnect
Alarm triggers when the airway pressure fails to exceed the PEEP setting by ~7 cm H
the user should quickly check the patient connection, breathing circuit connections and the exhalation valve.
At times this alarm can be caused by the patient breathing with the ventilator during inspiration which pre-
vents the PIP from passing the minimum pressure. While resolving the alarm condition the user should be
sure to manually ventilate the patient.
Mitigation/Info: Check Patient Connection, Check Circuit for Loose Hose/Tube, Check Exhalation Valve,
Check Patient, Replace Circuit, **Manually Ventilate Patient**
2110 Patient Detected
An alarm triggers when you connect the patient to the ventilator while the Start Menu is still active. To resolve
the alarm, you must select a mode of ventilation and configure the device appropriately for the patient. In
addition, you should perform the Operational Test procedure before reconnecting the patient to the device.
Mitigation/Info: Backup Ventilation Started, Set Mode (AC, SIMV, CPAP, BL), Configure Other Settings,
**Manually Ventilate Patient and Restart**
2170 Spont. Breath PIP High
Alarm triggers when the airway pressure, PIP, exceeds the High PIP Limit Setting during 2 consecutive spon-
taneous breaths. The user should quickly check for kinked hoses/ tubes and check for airway obstruction.
Suctioned the patient if necessary. The user should also check if the High PIP limit is set correctly of if the
pressure support (PS) level is set too high. While resolving the alarm condition the user should be sure to
manually ventilate the patient.
Mitigation/Info: Pressure Exceeds Limit Setting, Check Circuit for Kinked Hose/Tube, Check for Airway
Obstruction, Suction Airway if Necessary, Check High Limit Setting, **Manually Ventilate Patient**
2171 Spont. Breath PIP Low
Alarm triggers when the airway pressure, PIP, exceeds the Low PIP Limit Setting during 2 consecutive spon-
taneous breaths. The user should quickly check circuit for loose hoses/ tubes and also check the exhalation
valve and the tube placement/ cuff. The user should also check if the Low PIP Limit is set correctly. While
resolving the alarm condition the user should be sure to manually ventilate the patient.
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**
