Jan 01, 2003 · Blood oxygen saturation is a measure of the amount of oxygen carried by hemoglobin in the blood stream. It is usually expressed as a percentage rather than an absolute reading. Pulse oximeter s define this percentage in a different way than other instruments. These subtle, but important differences, are described in the following section.

pulse oximeter to measure the oxygen saturation of hemoglobin is that blood changes colour as hemoglobin absorbs varying amounts of light depending on its saturation with oxygen. Oxyhemoglobin does not absorb much red light, but as the hemoglobin oxygen saturation drops, more and more red light is absorbed and the blood becomes darker.
