An oximeter for measuring oxygen saturation in arterial blood includes a light source for projecting light to a body member to be measured, a light responsive circuit for receiving the light which has transmitted through said body member and for generating at least first, second and third signals at three different wavelengths, and a calculator for calculating at least first SaO.sub.2 data using first and second signals and second SaO.sub.2 data using first and third signals. It is detected whether or not a difference between the first and second SaO.sub.2 data is within a predetermined level. When the difference is within the predetermined level, it is assumed that the first and/or second SaO.sub.2 data are valid, but if not, they are assumed as invalid.
