Abstract:
A blood-pressure measurement apparatus provided with a variable-pressure and blood-flow stopping cuff which is adapted to be wrapped around an upper-arm portion of a living subject, that measures a blood pressure of said living subject by changing pressure of said cuff according to a predetermined speed, said apparatus comprising:a blood-flow-stopping means for stopping blood-flow at said upper-arm with said cuff; a pressure-pulse-wave sensor, equipped being combined with said cuff to detect a pressure-pulse-wave appearing at an upper-stream side than the blood-flow stopped position; and a heart function parameter calculating means for calculating a heart function parameter of said living subject, based on said detected pressure-pulse-wave at said upper-stream side by said sensor, while said cuff is stopping the blood-flow of said upper-arm portion.
