A small, electronic device called a pulse oximeter is clipped onto a part of the body, usually a fingertip. The device emits light that passes through the fingernail, skin, tissue, and blood. On the other side of the finger, a sensor detects and measures the amount of light that passes through the finger without getting absorbed by the tissue and blood. Using that measurement, the device calculates the oxygen saturation of the blood.
