At the latest at 0.3 Vol%
At the latest at 0.4 Vol% or 0.1 xMAC (the larger
value applies)
With a desflurane concentration greater than
4 Vol%, mixture detection occurs at the latest
when the concentration of the second anes-
thetic gas rises above 10 % of the desflurane
concentration.
The secondary gas becomes the primary gas
when the expiratory xMAC value is more than
0.2 xMAC above that of the primary gas.
The specified detection thresholds refer to rising
anesthetic gas concentrations (e.g., at the start
of an operation). If the anesthetic gas concen-
tration falls, a concentration of down to
0.05 Vol% will be measured, based on the last
anesthetic agent detected. Below this concen-
tration, a value of 0 Vol% will be displayed.
Based on patient age, anesthetic agent, and
nitrous oxide concentration
