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.ximetry 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.
