The article raises the pressing topic of the hemodynamic parameters and associated errors analysis, modern methods of the pulse wave accepting and analysis are considered The relationship between systems within the human body is noted. The most important indicators of the body normal functioning are noted. The factors affecting the final values of hemodynamic parameters are described. The hydroсuff method for recording a pulse wave curve is presented. The conducted experimental studies to identify the most informative sensorlocation with minimal losses in the amplitude-frequency characteristics of the recorded pulse wave signal are illustrated. The research results analysis and processing were performed using LabVIEW software. Graphic processing was carried out using MATLAB R2017b software. The pulse wave signals taken from various parts of the body were studied, it was concluded that to determine the hemodynamic parameters and blood pressure, it is sufficient to use a hydrocuff sensor fixed on the index finger. The respiratory system effect on the pulse wave amplitude-frequency characteristics has been experimentally confirmed. It is concluded that a number of studies are needed to learn the in formativeness of the respiratory signal involved in the formation of the pulse wave contour for the indirect assessment of the state of not only the cardiovascular system, but also the human respiratory system. |
