Key result
A hydrocuff sensor fixed on the index finger is sufficient to determine hemodynamic parameters and blood pressure, confirming the respiratory system's effect on pulse wave characteristics.
Why the study?
Analysis of hemodynamic parameters and associated errors is a pressing issue, requiring identification of the most informative sensor location with minimal signal losses.
Does a hydrocuff sensor fixed on the index finger provide sufficient pulse wave signals for determining hemodynamic parameters and blood pressure compared to other body parts?
Does a hydrocuff sensor fixed on the index finger provide sufficient pulse wave signals for determining hemodynamic parameters and blood pressure compared to other body parts?
A hydrocuff sensor on the index finger is an effective method for recording pulse wave curves to measure hemodynamics and blood pressure, while also capturing respiratory effects.
May enable convenient finger-based hemodynamic monitoring; leaves open validation against reference standards before clinical use.
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 hydrouff 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.
