碩士 === 中原大學 === 電機工程研究所 === 100 === Pulse pressure measurement system is the main way of this study. The system is divided into the wrist measurement system and the arm measurement system, both measured real-time pulse signal base on constant pressure, at the same time used simplify recording system and infrared optic system, to retrieve the pulse acoustic signal and PPG signal synchronization. This study is to use a three-channel acoustic, photonics, pressure synchronized measurement system measure and analysis of subjects. This study used to capture three-channel synchronization of physiological signals, obtained pulse signal, PPG signal, pulse acoustic signal on the five segments of constant pressure that basis of average pressure. SI and RI can be obtained by the PPG signal, and PWV can be obtained by the PPG signal and pulse signal. In addition, used pulse acoustic changes to obtained spectrum information. Do further evaluation.by analysis these real-time parameters of the physical condition. The parameters of the statistical data be obtained in this study allows the subjects to distinguish between the two groups according to different ages. Inference that the correspondence between study parameters and cardiovascular physiology. In this study, the multi-information parameters at the same time and get the same results in different approaches. Validate of new feasibility cardiovascular indicator by integrating the three-channel signal measurement system. This also means that parameters in the analysis of the cardiovascular physiological conditions have great significance on the future study.
