Operation monitoring and automatic control of heart supporting system require information about ventricular assist device output. One of non-invasive measurement methods is pneumatic' chamber resonant frequencies analyse. The acoustic noise brought inside pneumatic chamber is transformed by amplification or suppression of its frequency components. In consequence of this the received signal spectrum contains modified components of stimulation noise. Selected spectrum's regions parameters (like its maximal amplitude value or location along frequency axis) correlate with changes of pneumatic' chamber volume.
