CAUTION
1 Always set patient age correctly. Incorrect settings can lead to inappropriate MAC
values and therefore to inappropriate anesthetic gas delivery.
2 Age-based MAC values only apply if the patient’s age is ≥ 1 year. An aged-based
MAC of 1 year is used if the patient’s age is
< 1 year.
3 If patient age is not entered, the default age-based MAC of 40 years is used.

1 Plug the IRMA connector into the IRMA input and switch the power on.
2
Snap the IRMA sensor head on the top of the IRMA airway adapter. It will click into place
when properly seated.
