A pulse oximeter works by passing a beam of red and infrared light through a pulsating capillary bed. The ratio of red to infrared blood light that is transmitted is going to give you a measure of the oxygen saturation of your blood. The oximeter is going to work on the principle that the oxygenated blood is a brighter color of red than the deoxygenated blood, which in turn is more blue-purple. The oximeteris going to measure the sum of the intensity of both shades of red, which represents the fractions of the blood with and without oxygen in them. The oximeteris also going to detect the pulse and then subtracts the intensity of color that is detected when the pulse is absent. The remaining intensity of color is going to represent only the oxygenated red blood that you have. All of this valuable pulse information is going to be displayed on the electronic screen as a percentage of oxygen saturation in your blood.
