[A noninvasive and continuous method for blood pressure measurement using pulse wave].

This paper presents a method of noninvasive and continuous measurement of blood pressure by pulse wave. The method is realized by extracting the characteristic parameters of human brachial artery pulse wave and developing the stepwise regression equation. The experiment results showed that blood pressure measured by this method was well correlated with which measured by mercury sphygmomanometer. The mean difference of blood pressure was smaller than 3 mmHg, and the standard deviation was smaller than 5 mmHg.
