magnitude of this error will depend upon the level of oxygen and the
duration of exposure.
The anesthetic agents listed in the following table (Halothane,
Enflurane, Isoflurane, Sevoflurane, and Desflurane) were vaporized into
a stream of 30% oxygen / 70% nitrous oxide, and the resulting drops in
oxygen level after an exposure of approximately two hours were noted.
Exposures in excess of two hours may produce slightly greater
errors. The errors listed are typical for all oxygen sensors such as the
R17MED. Exposing the sensor to air or gases that do not contain
anesthetic agents for a period of time equal to or greater than the exposure
interval will eliminate the reading error in most cases.
