Abstract
A method for calculating blood oxygen saturation includes defining the extreme value point of a non-red light signal as the extreme value point of a red light signal, and calculating the blood oxygen saturation according to the extreme value point of the red light signal. The method for calculating blood oxygen saturation of the present disclosure proposes to use other light source signals to assist in finding the period of the red light signal, so that the calculation result of the red light signal is more accurate.
