Pulse Oximetry: A preferred non-invasive method allowing the monitoring of the oxygenation of a patient's hemoglobin.
A sensor is placed on a thin part of the patient's anatomy, usually a fingertip or earlobe, or in the case
of a neonate, across a foot, and a light containing both red and infrared wavelengths is passed from one
side to the other. Changing absorbance of each of the two wavelengths is measured, allowing determination
of the absorbances due to the pulsing arteria blood alone.
