    Abstract: A CPU detects pulse waves in a pressure signal of a cuff detected during a period of reducing pressure applied by the cuff to a measurement site and acquires blood flow sound signals corresponding to blood flow sounds occurring in the pressure reduction period. Then, data for a pulse wave envelope that associates the amplitude values of the detected pulse waves with the pressurizing pressures at the pulse wave generation times, and data for a blood flow sound envelope that associates the amplitude values of the blood flow sound signals with the pressurizing pressures at the blood flow sound generation times are generated, and the data for the pulse wave envelope and the data for the blood flow sound envelope are used to determine whether or not there is periodic variation in the blood pressure during the pressure reduction period.

    Abstract: The blood pressure measurement apparatus includes a pressure sensor that detects the pressure in a cuff and outputs a cuff pressure signal, and a pulse wave detection unit that detects a pulse wave in the cuff pressure signal. The pulse wave detection unit includes an analog HPF that extracts a high-frequency component from the cuff pressure signal, an A/D conversion unit, a signal storage unit that stores a signal obtained by performing A/D conversion on the cuff pressure signal detected at the time when the pressurizing pressure changes from increasing to decreasing, a subtraction unit that subtracts the signal stored by the signal storage unit from an output signal of the A/D conversion unit, and a digital HPF that extracts a high-frequency component from the output signal of the subtraction unit.
