Pulse oximetry is based on the principle that pulsatile blood absorbance of IR or red light changes with regard to degree of oxygenation. Complete working of the Missing Pulse Detector Circuitry is shown in the video given at the end. Developed pulse oximeters require: Accurate sensor measurement to derive oxygen saturation levels and heart rate.
