title: [Determination of the blood flow rate in the arteries and veins and its clinical significance].
abstract: A noninvasive ultrasonic method (a two-beam Doppler meter with separation of the direction) is suggested for quantitative assessment of localized disorders of hemodynamics of arterial blood flow and venous blood outflow. The authors measured the maximum and mean blood flow rate in the aorta and larger arteries and veins of 23 healthy persons and 94 patients with hypertensive disease, ischemic heart disease, and mitral valvular diseases. Experiments were conducted with measurement of the blood flow rate in the aorta, vena cava superior and pulmonary artery in dogs and the normal values were determined. A decrease in the rate of the blood flow in vessels in the diseases mentioned above, especially in circulatory insufficiency, was found, as well as local asymmetry.
