Message Priority Cause Action
Increase low MV
limit Medium Low MV limit is off in SIMV VCV, SIMV
PCV, SIMV PCV-VG, CPAP + PSV, or
PSVPro modes. Increase low MV alarm limit to improve
patient disconnection detection.
Insert cassette Low Cassette removal detected during
active delivery. Reinsert the cassette.
Inspiration
stopped Medium High airway pressure. Check system for blockages.
Internal failure.
System may shut
down. High Power controller software failure. Contact an authorized service
representative.
Internal failure.
System may shut
down. Medium Power controller software failure. Contact an authorized service
representative.
Low gas sample
flow Low Sample flow is less than 80% of
nominal flow for 20 seconds. Check for blockage in the airway
module sample gas line.
Memory
(EEPROM)
failure Low Software error. Contact an authorized service
representative.
Module fail. No
CO2, AA, O2
data. Medium Airway module hardware failure. Replace module.
Module not
compatible Low The monitoring module detected is not
compatible with system software. Remove the incompatible module. Use
a compatible module.
Move Bag/Vent
switch to Bag Medium Bag/Vent switch was in the Vent
position when the case was started. Move switch to the Bag position.
MVexp high Medium MVexp is greater than MVexp high
alarm limit (for nine breaths and one
minute has elapsed). Set the alarm limits appropriately.
Check the ventilation settings.
MVexp low Medium MVexp is less than MVexp low alarm
limit (for nine breaths and one minute
has elapsed). Set the alarm limits appropriately.
Check the ventilation settings.
N2O supply
pressure low Medium N2O pipeline pressure is less than 252
kPa (36 psi) and the N2O cylinder
pressure is less than 2633 kPa (381
psi). Ensure the N2O pipeline and cylinder
are properly connected.
Negative airway
pressure High Paw is less than -10 cmH2O. Check for blockages in the patient
circuit.
No battery
backup Medium Battery or charging failure. Between cases turn the system circuit
breaker off, then back on after 15
seconds to reset the system.
No exp flow
sensor Medium Electrical signals show the flow sensor
is not connected. Connect the flow sensor. Replace the
flow sensor if necessary.
No fresh gas
flow! High Possible patient detected while system
is in checkout state. Disconnect the patient or start the case.
No fresh gas
flow? High Possible fresh gas flow occlusion or
loss of gas pressure. Switch to circle circuit or bag the
patient. Check pipeline supply
connection.
No insp flow
sensor Medium Electrical signals show the flow sensor
is not connected. Connect the flow sensor. Replace the
flow sensor if necessary.
O2 flush stuck
on? Low Switch detected “on” continuously for
more than 30 seconds. Check flush valve. Ensure flush valve is
not sticking.
