System Messages
When monitoring CO
2
, the X Series unit may display the following messages:
System Message Cause
INITIALIZING The unit is initializing the CO
2
monitoring function
measurement, is functioning normally, and will display
CO
2
measurement after a brief delay.
CHECK FILTERLINE The sampling line is not connected. Check sampling line
connection. Replace airway adaptor or cannula, if
defective.
FILTERLINE OCCLUSION The sampling or exhaust line is blocked. Check sampling
and exhaust lines. Make sure that the sampling line and
any inputs to the patient breathing apparatus are not
connected to the exhaust port. If the current FilterLine is
correctly attached, replace the FilterLine.
AUTO ZERO The X Series unit displays AUTO ZERO when the CO
2
module performs periodic self-maintenance. During self-
maintenance, the CO
2
module performs one or more of
the following tests: ambient pressure measurement, auto
zero, and a flow test. The CO
2
module completes its self-
maintenance tests in approximately 10 seconds.
PURGING The CO
2
module performs a purging whenever it detects
an occlusion in the line or airway adaptor, and displays
PURGING while it tries to clear the occlusion. If the CO
2
module cannot clear the occlusion within 30 seconds, the
X Series unit issues an equipment alert and displays the
message
FILTERLINE OCCLUSION. At this point, if the
current FilterLine is correctly attached, replace the
FilterLine.
VALUE OVER RANGE The CO
2
value exceeds the specified range.
CO2 DISABLED An error has occurred with the CO
2
module, and the X
Series unit has disabled the module for the duration of the
unit’s power cycle. If the problem persists, the unit may
require servicing.
CO2 MONITORING FAILURE The X Series unit has determined that the CO
2
module is
not functioning correctly. If the problem persists, the unit
may require servicing.
