Abstract

A pulse photometer includes: an interface receiving a first signal and a second signal; and a processor configured to calculate a concentration of at least one blood light absorber in a subject, based on the first and second signals. The processor is configured to: acquire a first variation of the first light due to blood pulsation in the subject, acquire a second variation of the second light due to the pulsation, and calculate the concentration of the at least one blood light absorber, based on a first correction amount and a second correction amount. The first correction amount is based on at least one of a first constant, the first variation and the second variation, which are statistically determined. The second correction amount is based on at least one of a second constant, the first variation and the second variation, which are statistically determined.
