The possibilities of assessing the arterial vessels condition using a pulse wave

The paper considers the possibilities of assessing the condition of arterial vessels by processing and analyzing pulse wave signals. Such methods of pulse wave registration as photoplethysmography and sphygmography are described, as well as the meaning of the idea of primary signal processing. There are many examples of the use of these signals in medical and scientific practice: blood pressure assessment, respiratory parameters, elasticity of the vascular wall and the biological age of the vessels. Some of these parameters, such as respiratory wave, сardiointerval average duration and сardiointerval maximum duration, were determined by three signals, and compared with each other. Each of the three signals differed from the others in the noise level. The signals were processed in the Matlab using the developed algorithm based on the analysis of the contour characteristics of the pulse wave. The results of processing demonstrate the possibility of using the algorithm in the study of biomechanical and hemodynamic parameters.
