Possible Cause
The sensor is warming up.
See the remainder of this
table for other possible
causes.
The sensor is warming up.
The Capnogram is not
configured to be displayed.
The sampling line is not
properly connected
See
Table 23 "Zeroing Messages"
The CO
sensor has reached
2
its end of life.
The CO
sensor is over
2
heated.
The CO
sensor is
2
malfunctioning.
The CO
sensor is
2
connected but cannot
communicate with the
Efficia DFM100.
Your sensor needs to be
zeroed.
Your sensor has not reach its
proper operating
temperature.
The CO
value is out of the
2
measurement range.
For Sidestream sensors - your
sampling line is kinked or
blocked.
Potential Solution
No action required. As soon as the sensor has warmed
up and there is a detectable breath, the question mark is
removed from the display.
Check the associated technical alarms and address the
problem.
No action required. As soon as the sensor has warmed
up, the question mark is removed from the display.
Use the Displayed Waves menu to select a wave sector
to display the Capnogram.
Check all connections.
Check sampling line for knots, kinks or pinches.
on page 107 for possible causes and solutions.
Replace your sensor with a newer one.
Move any adjacent devices that may be heating the CO
sensor and remove anything covering the CO
that it is directly exposed to ambient air at a
temperature below 40° C.
Unplug the sensor and wait for it to cool down. If you
still get an over temp alarm, replace the sensor.
Replace the sensor
Unplug the CO
sensor and wait 10 seconds. If the
2
communication failure alarm remains, the Efficia DFM
100 requires servicing. If the alarm changes, plug the
sensor in firmly. If the Communication Failure returns,
replace the CO
sensor.
2
Disconnect sampling line from the patient and zero the
sensor. See
"Zeroing Sidestream and Mainstream
Sensors"
on page 106.
No action required. The technical alarm is removed
when the sensor reaches its operating temperature.
Zero the sensor. If the error remains and you suspect a
false high value, replace the CO
Check the sampling line for kinks or blockages and
remove if found.
Replace sampling line.
