Remedy
– Check the patient and treat
if necessary.
– Change the alarm limits.
– Make sure the mainstream
sensor is attached properly
to the adapter.
– If message persists, clean
or replace the airway adapt-
er.
– If message persists though
the airway adapter is clean,
zero the sensor.
Contact your technical per-
sonnel.
– Use the airway adapter
type the system is config-
ured for or adjust the airway
adapter setting (see
page 249).
– If the message persists,
clean or replace the airway
adapter.
– If the message persists
even though the correct air-
way adapter type is select-
2
ed and the airway adapter
is clean, zero the sensor.
– If the message still persists,
the inspiratory CO
might not be accurate.
Check the patient and ven-
tilation.
