Pulsatile power varies widely by CPB pump; hypothesis-generating for whether device choice affects clinical outcomes.
Do different cardiopulmonary bypass pumps generate different hydraulic power outputs in an artificial circulation system?
Cardiopulmonary bypass pumps differ markedly in their pulsatile power output, which may explain discrepancies in the observed clinical benefits of pulsatile blood flow.
G. Wright (1988) studied this question.
