Research And Design Of Computer Monitoring And Evaluation System Of Pulse Waveform Vascular State

With the increase of social pressure and the accelerated pace of life, people’s long-term irregular work and rest and bad eating habits make the incidence of cardiovascular disease is increasing, and become one of the major factors that threaten human health, at present, the incidence and mortality rate has been ranked first in the world. Prevention and cure of cardiovascular disease has become an important program in the world. If you can learn about the health of their blood vessels in real time through technical means, it can effectively avoid or prevent the occurrence of cardiovascular events.According to the research content of this project, for the current waveform analysis, blood pressure prediction, intelligent analysis and diagnosis of vascular status is not perfect, this paper designed a pulse waveform vascular state computer monitoring and evaluation system. This system from the pulse wave waveform preprocessing, waveform feature point selection, waveform parameter calculation, automatic waveform classification and establish prediction model of blood pressure and other aspects of the specific research. The ultimate goal is to improve the intelligent computer analysis of the practicability and accuracy, using computer software programming on a large number of pulse waveform classification, BP prediction model is established, and objective evaluation of the vascular state is given.The design of the dual pulse wave acquisition, can be real-time monitoring to obtain the measured pulse waveform, from the acquisition to the pulse waveform of the pulse waveform to a single cycle, through the double road cycle waveform acquisition, to calculate the velocity waveform classification, and to predict the blood pressure according to the regression model of each type of waveform, and related blood vessels through prediction of blood pressure parameters to evaluate the vascular status. In this project, I did the main part of the project is waveform pre processing, segmentation and cycle, the study of pulse waveform classification algorithm, a blood pressure prediction model and the pretreatment waveform, the division cycle, classification algorithm and establishment of process model is converted into a programming language, in order to achieve the calculation results of pulse waveform monitoring on the vascular status was evaluated.
