Abstract
We analyzed the dynamics of the interaction of rotary pump, connected to the scheme «the left ventricle – aor- ta», and left ventricle in norms and heart failure, using data obtained on the mock circulatory system. Adverse pumping states such as suction and regurgitation can be detected. These limits depend on the degree of cardiac failure, which confirms the need to control the speed of rotation of the impeller in the range of the cardiac failure from pathology to normal. It has been shown that the pulsating pressure at the inlet of the pump modulates the flow of the pump, making it a pulsating, what positively affects on the dynamics of cardiac output.
