Invalid circuit
module Informational Absorber switches do not detect a
valid breathing circuit module. Make sure the breathing system is correctly
installed. Continue to use normally. Contact a
Datex-Ohmeda trained service representative.
Limit task light use Informational The system is operating on battery
power. Manually ventilate the patient to save power.
Make sure power is connected and circuit
breakers are closed.
Loss of backup
audio Medium
(Informational after
acknowledge) Alarm audio malfunction. Continue to use normally. Contact a Datex-
Ohmeda trained service representative.
Low battery voltage Medium Voltage is less than 11.65V while
using battery power. Manually ventilate the patient to save power.
Make sure power is connected and circuit
breakers are closed.
Memory
(EEPROM) failure Informational The system cannot access some
stored values. Default settings are used. Ventilation is still
possible but service is necessary. Contact a
Datex-Ohmeda trained service representative.
Memory (flash)
failure Minimum shutdown
(High) Ventilator malfunction. Ventilate manually. Monitoring is not reliable.
Contact a Datex-Ohmeda trained service
representative.
Memory (redundant
storage) fail Minimum shutdown
(High) Ventilator malfunction. Ventilate manually. Monitoring is still available.
Contact a Datex-Ohmeda trained service
representative.
Monitoring only Medium A severe malfunction prevents
mechanical ventilation. Other alarms
may also occur. Ventilate manually. Cycle system power (On-
Standby-On). If the alarm clears, restart
mechanical ventilation. Contact a Datex-
Ohmeda trained service representative.
MVexp high Medium Exhaled minute volume is greater
than the high limit setting. This alarm
is suspended for nine breaths or one
minute (whichever is greater) after the
ventilator settings are changed. Check patient for spontaneous breathing. Adjust
control settings.
MVexp low Medium Exhaled minute volume less than the
low limit alarm setting. This alarm is
suspended for nine breaths or one
minute (whichever is greater) after the
ventilator settings are changed. Check patient condition. Check tubing
connections. Check alarm settings.
Negative airway
pressure High Subatmospheric pressure (less than
-10 cmH2O). Check the patient condition for spontaneous
activity. Increase fresh gas flow. Look for high
flow through gas scavenging. Calibrate the flow
sensors. With active scavenging, check the
negative relief valve on the receiver.
No CO2 absorption Medium
(Informational after
acknowledged)
Absorber canister is not latched when
CO2 bypass is in place. Check that the absorber canister is properly
latched. Continue to use the system normally.
Contact a Datex-Ohmeda trained service
representative.
No exp flow sensor Medium
(Informational after
acknowledge)
Electrical signals show the flow
sensor is not connected. Connect the flow sensors. Make sure the flow
sensor module is on all the way.
No insp flow sensor Medium
(Informational after
acknowledge)
Electrical signals show the flow
sensor is not connected. Connect the flow sensors. Make sure the flow
sensor module is on all the way.
No O2 pressure High (cannot be
silenced)
The O2 supply has failed for 10
seconds. Air flow will continue. Ventilate manually if
necessary. Connect a pipeline supply or install
an O2 cylinder.
O2 flush stuck on? Informational O2 flush flow is detected for greater
than or equal to 30 seconds. Stop pressing the O2 flush button. If this alarm
occurs when flush is not in use, contact a Datex-
Ohmeda trained service representative.
O2% high Medium O2% is greater than the alarm high
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.
