The actual aspects of the venous return regulation

The review have represented the results investigations, which had been directed by academician of the Russian Academy of Medical Science B.l. Tkachenko, concerning actual and disputable aspects of the one of the main systemic hemodynamic parameter venous return. The peculiarities of the relations between venous return and cardiac output, venous return and arterial pressure, venous return and central venous pressure, venous return and total peripheral resistance are discussed following action on the systemic circulation of the different stimuli such as pressor and depressor vasoactive drugs, extreme factors (hypoxia, hypothermia, postural changes). The problems of the relation of the negative intrathoracic pressure and venous return and dynamic relations of the superior and inferior vena cava flows in the formation of the venous return are also discussed. The authors have proposed the «two-wave» conception of the pressor reaction formation in the systemic circulation.
