Abstract
An electronic blood pressure meter determines, in an inflation process, pressure Ps correlated to systolic pressure, pressure Pd correlated to diastolic pressure and pulse wave period Pc, and then calculates deflation rate def−v in a deflation process based on a first formula (def−v=(Ps−Pd−mb1)×Pc/N, where N represents the number of required beats). Further, maximum inflation value Inf−max is calculated based on a second formula (Inf−max=def−v·(np×Pc+&agr;)+Ps+&bgr;1). The pressure is increased to reach the calculated maximum value and then deflation is started at the calculated deflation rate . The blood pressure meter can thus perform a precise measurement in a shortest time.
