| Summary: | The article presents a theoretical analysis of the dynamic interaction of the left ventricle assist axial pump and the cardiovascular system. It is shown the axial pumps are working in conditions «left ventricle- aorta» generates a pulsed flow. The slope of the flow-pressure characteristics determine the amplitude of the pulsation. Data are confirmed in the chronic experiments on the biological models with the extracorporeal connection of the pump. The possibility of using this characteristic for the develope of the automatic control systems to ensure adequate operation of the pump in range of the physical activity of a patient ‘s physical activity. |
