MAINSTREAM MESSAGES
Message/Symptom
Sensor not responding to
breaths. CO waveform always
2
at 0 mmHg with no messages
displayed.
or
CO waveform baseline
2
> 25 mmHg with no messages
displayed.
CHECK CO2 ADAPTER
displayed during each
inhalation. Message disappears
during exhalation.
CHECK CO2 ADAPTER
alternates with ZERO CO2
ADAPTER shortly after
breathing stops.
CHECK CO2 ADAPTER
CHECK CO2 SENSOR
CO2 IN ADAPTER: WAIT
REPLACE CO2 SENSOR
USE AIRWAY ADAPTER
ZERO CO2 ADAPTER
ZEROING CO2 ADAPTER
Possible Cause(s)
Sensor/Adapter was zeroed with a low level
of residual CO in the adapter. CO
2
baseline is set below 0 mmHg.
Airway adapter type was changed with unit
powered off. New sensor/adapter
combination has not been zeroed.
Sensor/Adapter was zeroed with a low level
of residual CO in the adapter. CO
2
baseline is set below 0 mmHg.
Usually caused when the airway adapter is
removed from the CAPNOSTAT 3, or when
there is an optical blockage on the windows
of the airway adapter.
May also be caused by not having
performed an adapter zero after changing
the adapter type.
Sensor cable not properly plugged in or
over temperature.
There is CO in the adapter when
2
attempting to zero.
Zeroing was attempted within 20 seconds
of previous zero operation.
Sensor is defective or incompatible
(message appears when "WARM UP'
message is displayed for more than 5
minutes).
CO sensor is on the "REF" or "0" cell when
2
zeroing is started.
Sensor cable connected to M Series unit for
the first time. Zeroing error or probe drift
error detected.
Adapter zeroing in progress.

Recommended Action(s)
Perform a mainstream airway adapter zero
as described in "Zeroing the Mainstream
2
Sensor/Airway Adapter" on page 6.
Perform a mainstream airway adapter zero
as described in "Zeroing the Mainstream
2
Sensor/Airway Adapter" on page 6.
Clean airway adapter and reattach it. If the
problem persists or the adapter type was
changed, perform a mainstream airway
adapter zero as described in "Zeroing the
Mainstream Sensor/Airway Adapter" on
page 6.
Check that sensor cable is plugged in and
properly seated in the connector.
Check that sensor is not exposed to
excessive heat.
If problem persists, replace sensor.
Remove adapter from CO
the patient's - and your own - exhaled
breaths, and ventilator exhaust valves.
Wait up to 20 seconds before retrying
adapter zero.
Replace sensor.
Remove CO sensor from the "REF" or "0"
2
cell and attach airway adapter to CO
sensor.
Perform a mainstream airway adapter zero
as described in "Zeroing the Mainstream
Sensor/Airway Adapter" on page 6.
Wait for adapter zeroing to finish.
