Hemodynamic evaluation of a new pulsatile flow generation method in cardiopulmonary bypass system

open access: yesВестник трансплантологии и искусственных органов, 2019
This paper proposes a new method of generating pulsatile flow using non-pulsating pumps (NPP) without modulating the rotation speed of the pump rotor. At the initial stage, this method was proposed for NPP-based cardiopulmonary bypass (CPB) systems.
