Abstract

The method for the examination of the state of a cardiovascular system provides for the determination of quantitative values, which characterize a blood supply occurring in each of examined parts of a body, and which correspond to the sum of absolute values of areas, enclosed by all positive and negative half-cycles formed by the first-order time derivative of a pulsation pressure, which oscillates inside a blood vessel of the examined part of the body. Sums and ratios of said values are computed for sampling populations of the body parts and are compared with the average statistical ranges of the appropriate values, sums and ratios, which were found as typical for both healthy organisms and for organisms having known pathological deviations. Results obtained thereby are interpreted for diagnosing the state of the cardiovascular system. The device comprises channels (5) provided for the measurement of the values characterizing the blood supply, the number of which channels corresponds to the number of the examined parts of the body. Each of the channels comprises an occlusion cuff (2) by which a pressure on the examined body part is exerted through a pneumatic splitter (7) from a source (1) of the variating pressure, a tachooscillation transducer (3) separating the first-order time derivative of the pulsation pressure applied upon the cuff (2), a unit (6) effecting the measurements of the quantitative values of the blood supply and a recording unit (4). The computation of the sums and of the ratios of the quantitative values characterizing the blood supply occuring in the sampling populations of the body parts, as well as their comparison with said average statical ranges is performed by a computing unit (29).
