Alarms and Troubleshooting
User’s Manual 3-23
LOW VTE
Patient circuit obstructed.
Clean, unblock, and/or properly connect the
patient circuit.
Leak in the patient circuit.
Check and properly connect the patient
circuit connections.
May be caused by increased resistance
across exhalation filter (such as excessive
moisture).
Exhalation block missing or disconnected.
Restore or connect the exhalation block
(refer to section
4.7, “Exhalation Block” ). If
the exhalation block has been removed or
replaced, calibrate the exhalation flow
sensor. Call your customer service
representative.
Adjustment of a Min VTE threshold when
the patient circuit is in a single-limb
configuration.
Set the Min VTE alarm limit to OFF.
If exhaled tidal volume monitoring is
required, use the double-limb circuit.
Inappropriate patient circuit.
Replace the patient circuit with an
appropriate one.
Exhalation flow sensor not properly
calibrated.
Calibrate the exhalation flow sensor.
Defective exhalation flow sensor.
Replace the defective component(s) and
calibrate the exhalation flow sensor. (Call
your customer service representative.
Adjustment of the Min VTE level too high. Modify the Min VTE level.
LOW VTI
Adjustment of the Min VTI level too high
(for PSV, CPAP, P A/C, P SIMV and V SIMV
modes)
Modify the Min VTI level.
Adjustment of the pressure level not
enough to reach the volume required (for
PSV, CPAP, P A/C, P SIMV and V SIMV
modes).
Modify the pressure level according to the
physician’s prescription.
Patient circuit obstructed or disconnected.
Clean, unblock, and/or reconnect the
patient circuit.
Inappropriate patient circuit. Replace the patient circuit.
Defective flow sensor or internal leak in the
machine.
Check patient, replace the device and call
your technician or customer service
representative.
NO PROXIMAL LINE2
The proximal pressure line is disconnected.
Connect proximal pressure line.
PATIENT
DISCONNECTION
*IF PERSISTS RESTART/SRVC
Adjustment of Min PIP too high. Decrease the Min PIP threshold.
Leak or loose connection in the patient
circuit.
Circuit disconnection from patient or
ventilator.
Check the patient circuit connections to the
ventilator; examine all connections for
leakage and tightness.
Replace the patient circuit if necessary.
Inspiratory flow exceeds 130 LPM.
Check Min PIP alarm setting.
Adjust Apnea alarm setting.
Inappropriate patient circuit. Replace the patient circuit.
Defective internal circuits of the machine or
pressure sensor.
Restart ventilator to see if alarm clears. If
not, have a qualified technician replace the
defective component(s) or call your
customer service representative.
