Abstract
The present application discloses a blood pressure measurement device, includes: a blood pressure measurement body configured to measure blood pressure based on photoplethysmogram (PPG); and a calibrator configured to measure blood pressure values based on Korotkoff sounds. The calibrator is further configured to provide initial calibration parameters to the blood pressure measurement body, and the blood pressure measurement body is further configured to collect an ECG signal and a PPG signal, calibrate a PPG parameter-blood pressure equation according to the initial calibration parameters, and calculate a blood pressure value according to the PPG parameter-blood pressure equation.
