LV filling pressure-based algorithms merit human testing; leaves open optimal rotary pump control under varying conditions.
Control algorithms for rotary blood pumps that rely on left ventricular filling pressure are more robust under varying circulatory conditions than other proposed parameters.
Lim et al. (2012) studied Rotary blood pump assistance (n=5). Parameter variations (cardiac contractility, systemic vascular resistance, total blood volume) was evaluated on Hemodynamic response and efficiency of rotary pump assistance. Previously proposed control strategies for rotary blood pumps performed poorly under highly varying circulatory conditions, whereas algorithms relying on left ventricular filling pressure were the most robust.
