Abstract:
Blood pressure (BP) is one of important physiological parameters which reflect the activity of cardiovascular system. The discriminant method of BP is the key to improve the accuracy of measurements. In this paper, the principle of oscillation method is introduced first. The factors that influence the accuracy of this method and the preprocessing of pulse wave are also analyzed. Then, an improvement method based on oscillation method is proposed by means of the flow progress diagram, which is applied to measuring BP simulator and human body. The measurements are compared with the standard values of BP simulator and the measurements by Korotkoff sound method respectively. The results validate that the accuracy and the repeatability of BP determination are improved dramatically.
