Cardiovascular diseases are the leading cause of death in the Word. According to experts, by 2030 the mortality rate from cardiovascular diseases will be more than 23 million people. Due to the huge shortage of donor organs, the development of new MBCS devices is an important task in modern biomedical engineering. The methods described in this article are the basis for the development of a unit for measuring volume, which is part of the biotechnological system of adaptive control of artificial ventricles of the heart.

Selection of the optimal measurement method and development of a volume measurement unit for solving the problem of continuous determination of the volume of liquid in the AVH.

An experimental comparison was made of three methods for measuring the hydrodynamic parameters of an AHV, namely, optical, electromagnetic, and electrical impedance. The data obtained show a significant advantage of the electrical imaging method in the dynamic measurement of the liquid volume in an AHV and its compliance with the accuracy requirements. This method has the least error, the signal is recorded directly in the ventricle's chamber, which reduces the influence of the rest of the stand. The experimental results obtained in the article are of great practical importance for the development of a biotechnological system for adaptive management of the artificial heart ventricles.
