Abstract. Cardiovascular
and cerebrovascular diseases presented in official statistics as circulatory
system diseases (BSC) are the leading causes of mortality in developed
countries. In the diagnosis and treatment of these diseases, information
is actively used on the state of the circulatory system and its individual
organs. Such information, in particular, comes from the analysis of data
obtained from measuring blood pressure (BP) in the accessible parts of the
human body. A new type of sensor for continuous
non-invasive blood pressure measurement is being considered here. Its work is
based on the principle of local pressure compensation. The positioning of the
sensor is carried out on the basis of the method of differential data
processing of a three-channel recording of a pulse wave signal, similar to the
method used for radar guidance on the target. This approach, combined with the
small size of the sensor, allows high-quality blood pressure measurements on
various arteries available for palpation. The article provides examples of the
data obtained for the case of the radial and carotid arteries. The developed
sensor can serve as the basis for the technology of continuous non-invasive
monitoring of the state of the cardiovascular system.
Key words: blood pressure, non-invasive measurement methods, hemodynamics, pulse
wave, pneumatic sensor, positioning.
