Implication

Should not yet change LVAD practice; leaves open real-world efficacy of flow-based adaptive control.

Structured PICO

P
Population
State-space mathematical model representing the interaction of a rotary left ventricular assist device (LVAD) with the left ventricle
I
Intervention
Feedback controller adjusting pump speed based on the slope of the minimum pump flow signal
O
Outcome
Controller performance in adapting to patient activities and preventing excessive pumping (suction)

A novel state-space mathematical model and feedback controller for rotary LVADs shows promise in simulations for automatically regulating pump speed to adapt to patient activities while preventing ventricular suction.
