TLDR
The higher frequency, “natural,” pulse was superior to both experimental pump pulses indicating the desirability of further defining the characteristics of an optimal pulse under various conditions of storage including hypothermia.About:

Journal ArticleDOI
Pulsatile and nonpulsatile cardiopulmonary bypass: review of a counterproductive controversy.
TL;DR: Failure to quantitate adequately the pulsatile components of flow in these studies prevents differentiation between effective and ineffective forms of pulsatile flow and makes comparison of studies difficult.
Journal ArticleDOI
Hemodynamic, metabolic, and hematologic effects of pulsatile cardiopulmonary bypass.
TL;DR: Cardiopulmonary bypass with pulsatile flow was found to offer the following statistically significant advantages: lower systemic vascular resistance (p) and lower systemicascular resistance (r) during extracorporeal circulation.
Journal ArticleDOI
To pulse or not to pulse.
TL;DR: Pulsatile and nonpulsatile blood flow have been intensely studied for cardiopulmonary bypass, isolated organ perfusion, and myocardial preservation and new methods to create pulsatile flow and their adaptation to the standard roller pump are discussed.

TL;DR: CorM-3 supplementation in standard University of Wisconsin solution has a significant impact on decreasing cellular and graft injury, and improving survival through its antiapoptotic effects, which are likely mediated through mitochondrial membrane stabilization.
Journal ArticleDOI
Beneficial effects of pulsatile perfusion in the hypertrophied ventricle during ventricular fibrillation.
TL;DR: If lower perfusion pressures are to be tolerated in patients with left ventricular hypertrophy, pulsatile perfusion with the bubble tubing technique may prevent the development of subendocardial ischemia or infarction.

Journal ArticleDOI
On the local reactions of the arterial wall to changes of internal pressure.
TL;DR: My attention was first directed to these phenomena by the occurrence of curves like that reproduced in Fig. 11, which showed the effect of a fall of arterial pressure produced by exI citing the central end of the depressor nerve on the volume of the hind leg of the rabbit, the sciatic and the nerves accompanying the femoral artery having been cut.
Journal ArticleDOI
Energy equivalent pressure.
TL;DR: In this article, the authors describe differences in steady and pulsatile blood flow in terms of an energy equivalent pressure, which is obtained by calculation from phasic flow and pressure measurements.
Journal ArticleDOI
Hydraulic Power Associated with Pulmonary Blood Flow and its Relation to Heart Rate
TL;DR: Pulmonary vascular dimensions and elasticity, which determine impedance, thus embody a mechanism whereby tachycardia can increase pulmonary blood flow by as much as 35% with an increase in pulmonary arterial input power of less than 5%, without the intervention of vasomotor activity.
