Abstract
A blood pressure measurement apparatus includes circuitry configured to: detect a pulse of a subject, and obtain a photoplethysmography signal; and obtain estimated blood pressure of the subject based on the photoplethysmography signal. The circuitry receives parameter information, generates time information based on the photoplethysmography signal, applies a blood pressure estimation equation to the time information and the parameter information to calculate the estimated blood pressure, receives basic blood pressure information for the subject and the time information, and performs learning processing of applying a learning operational equation to statistical time information, which is obtained by performing statistical processing on the time information, and the basic blood pressure information to update the parameter information.
