O and AA1: end-tidal (Et) and respiratory (Fi) values.
Where, AA1 represents one anesthetic gas of Des (desflurane), Iso (isoflurane), Enf (enflurane), Sev (sevoflurane)
and Hal (halothane).
AA1 waveform displays the main anesthetic gas waveforms.
Warning

Do not use flammable and explosive anesthetics such as ether and cyclopropane, so as to prevent
explosion.
6.10.3 MAC Value
Minimum alveolar concentration (MAC) is a standard for comparing the potency of inhalation anesthetics. 1
MAC represents the end-tidal concentration of an agent (at sea level) that, in 50 percent of a tested population,
prevents gross muscular movement in response to a painful, standardized stimulus.
The MAC value may be calculated and displayed by using end-tidal (Et) gas concentrations according to the
following formula:
Attention

Above formula does not consider the altitude.


Intended Use
The IRMA main stream multi-gas probe is intended to be connected to other medical devices for display of
real time and derived monitoring data of CO
2
, N
2
O, and the anesthetic agents Halothane, Enflurane,
Isoflurane, Sevoflurane and Desflurane.
It is intended to be connected to an animal breathing circuit for monitoring of inspired/expired gases during
anesthesia, recovery and respiratory care. It may be used in the operating suite, intensive care unit and animal
room settings for
＞
20 kg, 10
～
20 kg and
＜
10 kg animals.
It is not intended to be used as the only means of monitoring an animal. It shall always be used in
