[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.
