Mechanical circulatory assistance devices are vital for the patients with end-stage heart failure, who require heart transplantation but are in a waiting list due to the shortage of donor organs. This makes the development of the advanced MCS devices and artificial heart ventricles a crucial task. The systems for the dynamic and adaptive control of circulation parameters are required. AHV liquid volume measurement units must be developed to create such systems.

Objective – Determination of the optimal electrode system for the AHV liquid volume measurement unit based on the electrical impedance measurements.

The most significant geometrical parameters of the electrode systems for the impedance based AHV liquid volume measurement are determined. The optimal values of the geometrical parameters were found for the system of dynamic AHV liquid volume measurement. Results were confirmed by the numerical and experimental studies.

The obtained values of the optimal geometrical parameters of electrode systems will be used in development of biotechnical system of adaptive AHV control.
