[Use of rheoencephaloplethysmography in the quantitative assessment of blood flow, modules of arterial and venous volumetric elasticity and other hemodynamic parameters of the vessels of the head].
A noninvasive method has been developed for quantitative assessment of all major hemodynamic parameters in vessels of the head on the basis of symmetrical fronto-occipital rheoencephaloplethysmography, using an RPG 2-02 adapter and the techniques of classical venous occlusive plethysmography. Blood flow (cm3/min), arterial and venous blood filling (cm3), and arterial and venous volume elasticity modules (dyne/cm2) are measured separately, per 100 cm3 of tissue, for the left and the right hemispheres of the brain. The method sensitivity and practicability have been confirmed by studies of nitroglycerin-induced variation in the above-mentioned parameters.
