[Method of rheogram analysis based on separating out its arterial and venous components].
A method for rheogram analysis has been developed which enables one to separate the two components of a rheogram, i. e. the arterial and the venous ones. These two components reflect, respectively, the pulse fluctuations of the blood content of the arterial and the venous systems. Their separation is based on substantial differences between these fluctuations during a cardiac cycle. The method is used for synchronous recording of rheograms and their first derivatives, i. e. the differential rheograms. Data obtained with the use of the method make it possible to estimate the level of the blood content of the arterial network, the peripheral vascular resistance, and the conditions of the blood backflow from the venous network in a body region being examined.
