ZEROING CO2 ADAPTER
9650-1212-01 Rev. E
Possible Cause(s)
The sensor/adapter zero, or the LoFlo module
zero is finished.
The zero operation did not complete
successfully.
Possible Cause(s)
This is usually caused when the airway
adapter is removed from the
CAPNOSTAT 5 CO
2
is an optical blockage on the windows of the
airway adapter.
It may also be caused by not having
performed an adapter zero after changing
the adapter type (single patient use vs.
reusable).
The CAPNOSTAT 5 CO
not properly plugged in or is over
temperature.
There is CO in the airway adapter when
2
attempting to zero.
Zeroing was attempted within 20 seconds
of previous zero operation.
Negative CO detected. May be caused by
2
a sensor that was zeroed with CO
airway, or by an optical blockage of the
airway adapter.
Adapter zeroing is in progress.
Recommended Action(s)
No action required.
Clear the occlusion, remove any source of CO
and try zeroing again. If problem persists,
contact Technical Support.
Recommended Action(s)
Clean the airway adapter and reattach it. If
the problem persists or the adapter type
sensor, or when there was changed, perform a mainstream airway
adapter zero as described in "Zeroing the
Mainstream CAPNOSTAT 5 CO2 Sensor/
Airway Adapter" on page 5.
sensor cable is Check that the sensor cable is plugged in
2
and properly seated in the connector.
Check that the sensor is not exposed to
excessive heat.
If the problem persists, replace the sensor.
Remove airway adapter from CO
including the patient's, and your own
exhaled breaths, and ventilator exhaust
valves.
Wait up to 20 seconds before retrying a
mainstream airway adapter zero, as
described in "Zeroing the Mainstream
CAPNOSTAT 5 CO2 Sensor/Airway
Adapter" on page 5.
Check the airway adapter and clean if
in the necessary. Perform a mainstream airway
2
adapter zero as described in "Zeroing the
Mainstream CAPNOSTAT 5 CO2 Sensor/
Airway Adapter" on page 5.
Wait for the adapter zeroing to finish.
