Abstract
An apparatus and a method for measuring a respiration-induced blood pressure fluctuation are provided. A blood pressure calculating section calculates a pulse pressure of a subject. A pulse wave measuring section measures a pulse wave of the subject. A respiration-induced fluctuation calculating section calculates the respiration-induced blood pressure fluctuation of the subject as a pressure value, based on the pulse pressure and a fluctuation and an amplitude of the pulse wave in a given time period.
