What is the SpO2 Sensors?

The SpO2 Sensor is used in making Pulse oximetry to a pulse oximeter, which is a test that measures what proportion of the oxygen-carrying molecules in the blood (called hemoglobin) are actually carrying oxygen.

 

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. Now, there is a portable battery-operated pulse oximeters are also available for home blood-oxygen monitoring.
