Based on a theoretical treatment of light absorption and scattering by particulatesuspensions and spectrophotometric method establishing at many different wave-lengths,a method is presented for measuring pulsating blood constituent,and a sys-tem which measures continuously the oxygen saturation and heart rate is designed.Two wavelengths of light,red and infrared light,are utilized by this system to ana-lyze the change in the transmitted light caused by the flow of pulsating blood into the
