Gas composition related
errors
Note Gas composition errors may be in addition to the above normalized accuracy.
When adding errors, positive errors can have the effect of nulling out negative
errors.
Note Use of anesthetic agent could affect the errors by approximately -0.95%/%
volume agent.
When subjected to gas mixtures containing the following concentrations of
gases, the oxygen monitor has been tested to be within ±5% of the actual gas
concentration. Gas mixtures other than the ones listed below may result in an
accuracy of the oxygen monitor outside of the ±5% V/V.
