For correct measurements: to avoid large deviations, the measuring point should be completely naked, dry and free from "interferences" such as nail polishes, scratches, wounds, etc.Deviations of +/- 2% may occur.
How pulse oximeter works: Spectrophotometry is the working principle behind the pulse oximeter. It throws visible red light which is called as light emitter part of the device. This light passes through the blood and on the opposite side it is detected by another part of the device known as a photo-detector and likewise, we obtain oxygen saturation results.
Light sensors in the device detect these red blood cells carrying oxygen and can also detect deoxygenated blood. The oxygenated blood looks darker than deoxygenated blood and light sensors are highly sensitive to this change in the blood. It measures variations of light absorbed from oxygenated and deoxygenated blood and shows in form of reading on the device screen.
