To provide an oxygen saturation measurement apparatus which allows a user to recognize the stability level without continuously looking at displayed values of blood oxygen saturation (SpO2 values).
The oxygen saturation measurement apparatus 100 comprises: a measurement section 2 that acquires a living body information signal by emitting infrared light or red light to a living body and receiving light passed through the living body; an analysis processing section 42 that calculates blood oxygen saturation by analyzing and processing the living body information signal; a stability determination section 43 that determines the stability and the stability level of the blood oxygen saturation on the basis of the value acquired by analysis and processing of the analysis processing section 42; and a display section 6 that displays the blood oxygen saturation calculated by the analysis processing section 42. When the blood oxygen saturation is determined to be stable by the stability determination section 43, the display section 6 displays the blood oxygen saturation in a fixed manner and also displays the stability level acquired when the stability determination section 43 determines that the blood oxygen saturation is stable.
