Carbon dioxide concentrations
Connecting the CO
Before connecting any CO
the airway adapter that is used, matches the airway
adapter setting of the M540 (see page 249). For ex-
ample, you should not use a disposable airway
adapter if the M540 is configured for a reusable air-
way adapter (and vice versa). Not aligning the
adapter with the configuration setting at the M540
compromises the displayed CO
The M540 is only compatible with the CO
6871950 revision 5 or higher. Previous revisions
are not compatible.
