8.6.1 Breathing gas measurement and xMAC display (MAC multiple)
Prerequisite: The device is equipped with the "integrated patient-gas measurement
module".
The MAC value is a guideline for anesthetic agent delivery.
The device displays the measured inspiratory and expiratory values for O
2, N2O,
and anesthetic gases, as well as the xMAC in the monitoring area. The nitrous
oxide concentration or anesthetic gas concentration is only displayed when it is not
zero.
The xMAC is the MAC multiple calculated from the current expiratory measured
values and the age-dependent MAC values. If no respiratory phases are detected,
expiratory values and xMAC cannot be displayed.
The integrated MAC algorithm is based on the MAC values shown in the following
table. These values are guiding values only. The binding values are specified on the
package information leaflet of the anesthetic agent.
The MAC values depend on the age of the patient. The values specified in the table
apply to a patient age of 40 years.
