[The RA6-02 rheoanalyzer for studying systemic hemodynamics by the methods of tetrapolar and focusing rheography].

The paper analyzes automatic rheographic (impedance) equipment, shows the prospects for using rheography to study systemic hemodynamics, as well as describes the potentialities of a new universal rheoanalyzer by employing tetrapolar and focusing rheography. The device uses an algorithm of automatic recording and processing rheosignals, which has been developed on 20-year worldwide experience in applying rheography. Specific volumetric and velocity parameters, as well as total amplitude-time parameters of rheosignals and their ratios, which virtually satisfy all users are identified in the procedures for examining hemodynamics in the heart, extremity, head, liver and lung.

[The RA5-01 rheoanalyzer].

The diagnostic potentialities and technical characteristics of the first series-produced automated device for recording and processing of the rheocardio-, rheovaso- and rheoencephalosignals are described. The device is fitted out with a three-channel rheotransducer, a microprocessor analyzer equipped with a representation unit and a recorder for tracing the processed data on electrographic paper. Five diagnostic techniques are reviewed.

[Algorithm for the automated processing of rheosignals].

Algorithm for rheosignals recognition for a microprocessing device with a representation apparatus and with automated and manual cursor control was examined. The algorithm permits to automate rheosignals registrating and processing taking into account their changeability.
