A pulse oximeter is a medical device that indirectly measures the oxygen saturation of a patients blood
(as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin,
producing a photoplethysmograph. It is often attached to a medical monitor so staff can see a patients oxygenation at all times.
Portable battery-operated pulse oximeters are also available for home blood-oxygen monitoring.
