Shear Stress, Energy Losses, and Costs: A Resolved Dilemma of Pulsatile Cardiac Assist Devices

<table>Perfusions curves (<i>in vitro</i>). Perfusion curves (in mmHg) obtained at different circuit sites in 3 different pulsatile tube positions: I, II, and III close and distant from aortic cannula and pre-oxygenator, respectively. The perfusion curve amplitude was significantly higher at P5 with position I, compared to positions II and III.</table>
