6 Alarms and Troubleshooting
M1132382
6-5
Battery failure high Informational Battery voltage greater than 16 V for
10 seconds. System is operational, but may fail on battery if
mains power is lost. Contact a Datex-Ohmeda
trained service representative.
Battery failure low Informational The battery voltage is too low (less
than 7 V) to supply the system if
power fails. System is operational, but will fail on battery if
mains power is lost. Leave the system plugged
in to charge the battery. If the battery does not
charge in 24 hours, contact a Datex-Ohmeda
trained service representative.
Calibrate flow
sensors Informational The last flow sensor calibration failed. Zero the flow sensors. Look for water in the flow
sensor tubes and dry if necessary. Replace
sensor if necessary. Contact a Datex-Ohmeda
trained service representative if calibrating or
replacing the sensor does not correct the
problem.
Calibrate O2
sensor Informational Calibration failure or O2% > 110%. Calibrate the O2 sensor. Replace the sensor if
calibration is unsuccessful. Contact a Datex-
Ohmeda trained service representative if
calibrating or replacing the sensor does not
correct problem.
Cardiac bypass Informational The Cardiac Bypass option is set to
On. Apnea alarms are off. Set Cardiac Bypass to Off in the Main Menu.
Check flow sensors Medium
(Informational after
acknowledge)
System has detected an improper flow
pattern in the breathing circuit. Check if the flow sensors are correctly installed.
Check for water buildup in the flow sensor
tubes. Inspect one way valves (breathing circuit
module.) Check the condition of the flow sensor
and its tubing.
Circuit leak Medium Exhaled volume less than 50% of
inspired volume for at least 30
seconds (mechanical ventilation). Check breathing circuit and flow sensor
connections. Patient circuit leak audio can be
turned off in the Alarm Setup menu.
Circuit leak audio
off Informational Leak Audio is set to Off on the Alarm
Setup menu. Turn Leak Audio to On on the Alarm Setup
menu.
Connect O2 sensor Medium O2 cell is not installed in the breathing
system. The O2 cell is not measuring
gas in the breathing circuit. Install or replace the O2 cell.
CPU failure Minimum shutdown
(High) Ventilator malfunction. Ventilate manually. Monitoring is not reliable.
Contact a Datex-Ohmeda trained service
representative.
Display failure Medium Backlight input supply is less than
9.35V or greater than 13.65V. This
alarm message may not always be
viewable. Continue to use the system normally. Contact a
Datex-Ohmeda trained service representative.
Dry or replace flow
sensors Medium
(Informational after
acknowledge) Expired volume is greater than
inspired volume for six breaths with a
circle module. Check patient condition. Check that the flow
sensors are installed correctly. Check that there
is no water buildup in the flow sensor tubes.
Verify proper check valve operation. Inspect one
way valves (breathing circuit module). Replace
flow sensors.
Gas inlet valve
failure Minimum shutdown
(High) Ventilator pressure sensor
malfunction. Ventilate manually. Monitoring is not available.
Contact a Datex-Ohmeda trained service
representative.
Increase low MV
limit Medium The low MV limit is set to Off. Turn on the MV low setting.
Inspiration stopped High Drive gas safety switch activated (high
pressure). Adjust the controls. Check the system for
blockages. Contact a Datex-Ohmeda trained
service representative if problem continues.
Internal ventilator
clock too fast Minimum shutdown
(High) Ventilator malfunction. Ventilate manually. Monitoring is not reliable.
Contact a Datex-Ohmeda trained service
representative.
Internal ventilator
clock too slow Minimum shutdown
(High) Ventilator malfunction. Ventilate manually. Monitoring is not reliable.
Contact a Datex-Ohmeda trained service
representative.
