System and method for blood pressure measurement, computer program product using the method, and computer-readable recording medium thereof

A method for measuring a blood pressure of a human who has a heart and a wrist, comprising:

• providing an initial personal electrophysiological signal by measuring a pulse signal from a sensor device which is worn on the wrist;
• providing a basic personal information through an electronic device;
• storing the initial personal electrophysiological signal and the basic personal information in a cloud server;
• establishing a personalized cardiovascular model built from the wrist continuously extending to the heart and implemented by the cloud server, wherein the personalized cardiovascular model is constituted as a finite element model, wherein the finite element model is set by a plurality of model parameters to distill a physiological information of the human, wherein the plurality of model parameters is built based on the initial personal electrophysiological signal and the basic personal information;
• calibrating and optimizing the personalized cardiovascular model through an optimization algorithm in the cloud server to obtain an adjusted plurality of model parameters;
• establishing a re-established cardiovascular model set by the adjusted plurality of model parameter and a latest personal electrophysiological signal;
• measuring the latest personal electrophysiological signal from the sensor device;
• and
• obtaining the blood pressure from the physiological information of the human through the re-established cardiovascular model.
