The master's thesis focuses on left ventricular assist devices (LVADs), which use a centrifugal turbine pump to support patients with severe heart failure. The main problem with current LVAD turbine pumps is the lack of flow and pressure regulation in short time intervals hindering patients' quality of life. The thesis includes a review of LVAD turbine pumps, their classification, and clinical applications. It aims to measure the pump's performance characteristics and test its responsiveness under various conditions. Two measurement stations will be designed: one to measure the pump's performance based on rotational frequency and the other to simulate resistances in the circulatory system and monitor the pump's response to variable resistance characteristics. The research's long-term goal is to develop a control system for LVAD turbine pumps, providing precise and adaptive mechanical support to the heart system and improving patient treatment outcomes.
