What is a pulse oximeter?
The small medical device used to measure the oxygen level in pulsating blood is called a pulse oximeter. It calculates the oxygen percentage in the blood and the person’s heart rate. Basically, haemoglobin is responsible for acting as a carrier of oxygen in human blood. This percentage of haemoglobin carrying oxygen is termed oxygen saturation.

Working
The oximeter is fitted with a light emitter on one end and a light detector on the other. It is in between these two ends that one can keep their finger. Generally, the oxygen-saturated and deoxygenated haemoglobin of the blood receives these lights at a different wavelengths.
There are two lights that are emitted: Red light and Infrared light. This pulse oximeter takes up the task of comparing the absorbed red and infrared light, thereby giving saturated oxygen levels (SP02).
