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.

pulse oximetry

oximetry performed noninvasively, usually on the finger or ear lobe, in which the small increase in absorption of light during the systolic pulse is used to calculate oxygen saturation.

pulse oximetry

Oxygen saturation measurement, SaO Critical care
A method used to determine the O2 saturation–SaO2 and desaturation of blood in a continuous noninvasive fashion, through the noninvasive assessment of arterial Hb-bound O2 saturation, based on the combined techniques of optical plethysmography and spectrophotometry; PO is accurate within 5% of a standard co-oximeter when the SaO2 is in the 70-100% range; accuracy plummets below 70%; PO is used to detect O2 desaturation accurately, inexpensively, quickly, safely, and is useful in endoscopy, recovery, intensive care, and for evaluating obstructive sleep apnea syndrome, for which the gold standard is the costly and onerous nocturnal polysomnography

oximetry

measurement of the oxygen content of arterial blood.

pulse oximetry
use of a spectrophotoelectric instrument applied to the skin which measures pulse rate and the percentage of oxygenated and reduced hemoglobin.
