Abstract

A blood pressure measurement method and apparatus, a blood pressure measurement device, and a storage medium, relating to the field of wearable devices. The blood pressure measurement method comprises: in a measurement state, obtaining a pressure signal acquired by a pressure sensor, wherein the pressure signal is used for representing the pressures corresponding to a plurality of sampling points in the blood pressure measurement process; extracting a first part pulse wave signal from the pressure signal; determining a signal offset of the first part pulse wave signal, wherein the signal offset is used for representing the difference between the first part pulse wave signal measured by a wrist blood pressure measurement device and a second part pulse wave signal measured by a second blood pressure measurement device; and on the basis of the signal offset, the first part pulse wave signal, and the pressure signal, determining a blood pressure measurement value. According to the measurement method, errors caused by factors such as the airbag width and different physiological structures of first and second parts can be eliminated, and the accuracy of blood pressure measurement is improved.
