An Analysis of Measurement Signals in Ventricle Assist Device in Terms of Their Diagnostic Usefulness

In this paper an analysis of the available measurement signals in external, pulsatile ventricular assist pump is carried out to evaluate their diagnostic usefulness, and to propose diagnostic system for such devices. Firstly, short description of device and used methodology is provided. Then a full set of diagnostic test is described. Next, diagnostic matrixes are defined. Paper ends with an analysis of the influence of measurements set on accuracy of diagnostic system.
