Problems
CAL and CO2 calibration
are not displayed after
connecting the CO2 sensor
to the monitor.
After the CO2 sensor is
inserted, CO2 waveforms
stay a flat line.
Possible Causes
The CO2 sensor is
malfunctioning.
Recommended Actions
The CO2 sensor needs to
be returned to manufacturer
for service.
The CO2 sensor is
malfunctioning or not
calibrated properly.
The CO2 function is not
working properly. The
waveforms are erratic.
The airway adapter is dirty
inside or damaged. The
airway adapter can not be
cleaned.
Re-calibrate the CO2
sensor, and then test it on
yourself by breathing
through it. If still the same,
the CO2 sensor needs to be
serviced.
Insert another airway
adapter, and then recalibrate the CO2 sensor.
The airway adapter is semidisposable, and needs to
be replaced frequently.
