Abstract

The invention relates to a dual-PPG (Photoplethysmography)-based blood pressure measuring method and device. The method comprises the following steps: penetrating human tissues by using projection light, wherein the influence factor of the light absorption of the human tissues can be obtained according to a Beer-Lambert law: log(I0 / I)=epsilonCl; reflecting the change of blood volume through a PPG signal; calculating the blood pressure by using PTT (Push to Talk). The method and the device have the advantages that self-detection can be realized through the blood pressure measurement based on PPG, and the all-day blood pressure can be better monitored based on continuous blood pressure monitoring of PPG in order to reflect the diurnal change situation of the blood pressure. The method and the device have important significance to the prevention of sudden cardiovascular diseases. Through the continuous blood pressure measurement based on PPG, the treatment of hypotensive drugs can be well monitored. Compared with other continuous blood pressure measurement, the continuous blood pressure measurement way based on PPG has remarkable advantages.
