Pulse oximetry is a 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 body, usually a fingertip or earlobe, or in the case of an infant, across a foot. Light of two different wavelengths is passed through the patient to a photodetector. The changing absorbance at each of the wavelengths is measured, allowing determination of the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) fingernail polish.
The device used for pulse oximetry is called a pulse oximeter.
For OSCAR compatible Oximeters see the OSCAR supported machines#Pulse Oximeters wiki page.
