Abstract
An electronic device receives a first input, where an air pump inflates and pressurizes an airbag. The electronic device obtains a pressure value of the airbag in a process of controlling the air pump to inflate and pressurize the airbag. The electronic device obtains a first pressure signal, where the first pressure signal is a signal indicating that the pressure value of the airbag changes with time in a process in which the air pump starts to inflate and pressurize the airbag until the pressure value of the airbag is equal to a preset pressure value. The electronic device determines, based on the first pressure signal, tightness of wearing a wristband by a user. The electronic device corrects, based on the tightness, a blood pressure measurement value determined based on a second pressure signal, to determine a blood pressure value of the user.
