This sensor is useful in making Pulse oximetry, which is a test that measures what proportion of the oxygen-carrying molecules in the blood (called hemoglobin) are actually carrying oxygen. This is known as oxygen saturation or SpO2. One hundred percent oxygen saturation is attained when all hemoglobin in the blood is completely saturated with oxygen. This simple test does not require a blood sample and is called non-invasive. Useful in sensing oxygen level of blood as well as heart rate.
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.
