oximetry

[ok-sim´ĕ-tre]

measurement of oxygen saturation of the blood using an oximeter.

pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin, using a pulse oximeter.

ox·im·e·try

(ok-sim'ĕ-trē),

Procedure using a device to measure oxygen saturation by fluctations of light absorption in well-vascularized tissue during systole and diastole. The underlying principle is the Beer law, or the relationship between the amount of light absorbed by a solute in solution and the concentration of the unknown solute.
