Technical data
Accuracy
±(0.2 Vol% + 15 % relative)
±(0.2 kPa + 15 % relative)
Resolution of displayed value
0.1 Vol% (kPa) for desflurane
0.01 Vol% (kPa) for all other anesthetic gases
T
10...90
<500 ms
Anesthetic agent identification
Automatic
Primary gas
At the latest at 0.3 Vol%
Secondary gas
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.
Minimum displayed concentration
The specified detection thresholds refer to ris-
ing anesthetic gas concentrations (e.g., at the
start of surgery). 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.
xMAC
Based on the age of the patient, the anesthetic
gas concentration, and the nitrous oxide con-
centration (the xMAC value is corrected for
ambient pressure)
Range
0 to 9.9
Accuracy
Refer to the accuracies of the respective mea-
sured gas values.
