Implication

Motor current analysis may flag suction in animal centrifugal pumps; leaves open translation to clinical LVAD speed control.

Structured PICO

Population

Mock circulatory loop with a pivot bearing supported sealless centrifugal pump in left ventricular apex to aorta bypass mode, using a pneumatic pulsatile ventricle and a collapsible rubber tube to simulate suction.

Intervention

Analysis of motor current waveform (fast Fourier transform analysis) to detect suction effect.

Outcome

Correlation between pump flow and motor current waveforms, and detection of suction effect via harmonic components of motor current power density.surrogate

Analysis of the motor current waveform can detect and potentially prevent the suction effect of a centrifugal blood pump, offering a method for automatic pump speed control.
