6-7
O2% low High O2% is less than the alarm low limit
setting. Verify that the limit it set correctly. Check that
the O2 flow is adequate. Calibrate the O2
sensor. If calibration fails, replace the O2
sensor. As the cell wears out, the measured %
of O2 decreases.
PEEP high.
Blockage? Minimum shutdown
(High) Paw greater than 100 cmH2O for 10
seconds. Check the tubing and breathing system for
blockages. Ventilate manually. Contact a Datex-
Ohmeda trained service representative.
PEEP high.
Blockage? High Paw greater than or equal to
sustained pressure limit for 15
seconds
1
.
Check tubing for kinks, blockages, disconnects.
Calibrate the flow sensors.
Plug in power
cable. On battery. Medium
(Informational after
acknowledge) The mains supply is not connected or
has failed and the system is using
battery power. Ventilate manually to save power. At full charge,
the battery permits approximately 90 minutes of
mechanical ventilation. Make sure power is
connected and circuit breakers are closed.
Positive SIB Vref
out-of-range Minimum shutdown
(High) Ventilator malfunction. Ventilate manually. Monitoring is still available.
Contact a Datex-Ohmeda trained service
representative.
Ppeak high High Ppeak is greater than Pmax. The
ventilator cycles to expiration. Verify Pmax and other controls are set correctly.
Look for blockages. Check patient connection.
Ppeak low. Leak? Medium Ppeak is less than 4 cm above Pmin
for 20 seconds when RR is greater
than or equal to four.
Ppeak is less than 4 cm above Pmin
for 35 seconds when RR is less than
four. Verify circuit connections are okay. Look at the
Paw gauge on the absorber. Look for circuit
disconnection.
Pressure/volume
monitor inactive Medium
(Informational after
acknowledge) The outlet selection switch is set to
the ACGO. Connect the patient circuit to the auxiliary outlet.
For mechanical ventilation or ventilation with
monitoring, select the circle system setting.
Replace exp flow
sensor Informational The system cannot read the
calibration data stored in the sensor. Operation continues with reduced accuracy.
Replace the flow sensor.
Replace insp flow
sensor Informational The system cannot read the
calibration data stored in the sensor. Operation continues with reduced accuracy.
Replace the flow sensor.
Replace O2 sensor Informational O2% is less than 5%. Make sure the patient receives O2. Use a
different monitor. Calibrate the O2 sensor.
Replace the O2 cell.
Reverse exp flow Medium
(Informational after
acknowledge) Flow through the expiratory sensor
during inspiration (for six breaths in a
row). Look at the check valves. Check for water
buildup in the flow sensor tubes. Check the flow
sensor condition. Replace the expiratory check
valve.
Reverse insp flow Medium
(Informational after
acknowledge) Flow through the inspiratory sensor
during expiration (for six breaths in a
row). Look at the check valves. Check for water
buildup in the flow sensor tubes. Check the flow
sensor condition. Replace the expiratory check
valve.
Select gas outlet Medium With ACGO On, the flow sensors
have detected three breaths in patient
circuit during the last 30 seconds. Turn the ACGO off or connect the non-circle
patient circuit to the ACGO. Note: The bag arm
will not ventilate a patient at the auxiliary outlet.
Service calibration Informational Corrupt or invalid calibration data for
the flow valve. The system is operational. Contact a Datex-
Ohmeda trained service representative.
Software error Minimum
Shutdown (High) Indicates that a software error has
occurred. Ventilate manually. Monitoring is not reliable.
Contact a Datex-Ohmeda trained service
representative.
Software/Hardware
Incompatibility Minimum
Shutdown (High) Compatibility error between the
software and the hardware. Ventilate manually. Contact a Datex-Ohmeda
trained service representative.
System leak? Medium
(Informational after
acknowledge) Leak detected between ventilator and
patient circuit. Look for leaks in the absorber system. Check
the integrity of the flow sensors. Zero the flow
sensors. Inspect for leaks (repair). Inspect or
replace flow sensors.
TFS module error Informational TFS module connected but not
operating correctly. System is operational, but TFS is not
functioning correctly. Contact a Datex-Ohmeda
trained service representative.
