8.5. Zeroing Masimo CO
2
Modules
For the IRMA (mainstream) CO
2
module, zeroing is performed by snapping a
new IRMA airway adapter onto the IRMA module, without connecting the airway
adapter to the patient circuit, and then pressing the Zero Set menu button in the
Setup CO
2
menu. An alert tone will sound when the zeroing procedure has
started, along with a “CO
2
zeroing” message. The alert tone will resound when
the zeroing procedure has completed.
Special care should be taken to avoid breathing near the airway adapter before or
during the Zeroing procedure. The presence of ambient air (21% O
2
and 0% CO
2
)
in the IRMA airway adapter is of crucial importance for a successful zeroing.
Zeroing needs to be performed only when an offset in gas values is observed, or
when the “CO
2
needs zeroing” message is displayed. When initially connecting
the IRMA CO
2
probe to the PPM3 or when changing IRMA airway adapters,
allow a 10-second warm-up period before initiating the zeroing procedure.
