May be caused by a module that was
zeroed with CO in the sample line.

Module zeroing in progress.
Recommended Action(s)
Verify that the sample line is plugged into
the module and seated properly.
Verify that neither the sample line nor the
exhaust tube are blocked, kinked, or
pinched. Verify that the airway adapter is
not blocked. If the sample line, exhaust
tube, or the airway adapter is blocked or
otherwise compromised for 15 seconds,
this message will appear. The pump will
shut off after 2 minutes if the condition that
caused the message is not cleared. To
restart the pump, correct the blockage, then
remove and reinsert the sample cell into the
sample cell receptacle.
If the problem persists, replace the sample
line.
Check that module cable is plugged in and
seated properly in the connector.
Check that module is not exposed to
excessive heat.
If problem persists, replace module.
Wait up to 20 seconds before retrying
module zero.
Remove adapter or cannula tip from CO
source including the patient's - and your
own - exhaled breaths, and ventilator
exhaust valves.
Perform module zero as described in
"Zeroing the LoFlo CO2 Module/Sample
Cell" on page 7.
Wait for module zeroing to finish.
