Key result
A newly developed disposable pulsatile blood pump delivered up to 40 mW of pulsatile hydraulic power at 5 L/min flow, compared to approximately 15 mW for a standard roller pump in pulsatile mode.
Why the study?
Does a newly conceived disposable pulsatile blood pump deliver higher pulsatile hydraulic power compared to a roller pump in an in vitro model of adult systemic circulation?
Population
In vitro model circuit with a mock hydraulic bench representing an adult patient's systemic circulation
Comparison
Newly conceived disposable pulsatile blood pump… vs Roller pump used in pulsatile mode (RP-PM)

May support more physiologic pulsatile flow in bypass circuits; hypothesis-generating for clinical outcomes in humans.
Does a newly conceived disposable pulsatile blood pump deliver higher pulsatile hydraulic power compared to a roller pump in an in vitro model of adult systemic circulation?
Absolute Event Rate: 40% vs 15%
A newly developed disposable pulsatile pump for cardiopulmonary bypass delivered greater pulsatile hydraulic power than a standard roller pump in an in vitro model, providing conditions closer to the natural heart.
Fiore et al. (2002) studied Cardiopulmonary bypass. New disposable pulsatile blood pump vs. Roller pump used in pulsatile mode (RP-PM) was evaluated on Pulsatile hydraulic power delivered at a 5 L/min flow rate. A newly developed disposable pulsatile blood pump delivered up to 40 mW of pulsatile hydraulic power at 5 L/min flow, compared to approximately 15 mW for a standard roller pump in pulsatile mode.
