Comparative Study
Comparison of use of an infrared anesthetic gas monitor and refractometry for measurement of anesthetic agent concentrations.
To assess agreement between anesthetic agent concentrations measured by use of an infrared anesthetic gas monitor (IAGM) and refractometry. SAMPLE-4 IAGMs of the same type and 1 refractometer. ⋯ Given that the assumption of linearity is a cornerstone of anesthetic monitor calibration, this assumption should be confirmed before anesthetic monitors are used in experiments.
