Correction of the flow measurement under the influence of desflurane
Hot wire volume monitors, which are not
compensated for desflurane, measure volumes
that are too great when the desflurane
concentration is high. See instructions for use for
the monitor used.
Correcting values for the minute volume MV
Correcting values for tidal volume VT
Example:
– Desflurane concentration 8 Vol%
– Displayed minute volume MV 10 L/min
