Abstract

Mechanical heart supporting is one of possible therapies in case of circulatory system insufficiency. It is realized by application of various types of Ventricular Assist Devices (VAD). For monitoring, optimizing and automatic control of heart supporting process it is necessary to measure blood volume pumped through the VAD during single cycle. The paper presents a novel approach to the problem of reliable VAD’s output estimation by the use of membrane’s shape pattern recognition and related blood’s chamber volume determination. Among many possibilities, the application of pattern recognition system has been decided leading to the promising results and making possible implementation of the automatic control algorithm in the future for the whole measurement process.
