1 Does Roller Pump–Induced Pulsatile CPB Perfusion Affect Microvascular Fluid Shifts and Tissue Perfusion?  Bjørg Elvevoll, MD, Steinar Lundemoen, MD, PhD, Øyvind S. Svendsen, MD, PhD, Arve Mongstad, CCP, Ketil Grong, MD, PhD, Venny L. Kvalheim, MD, PhD, Paul Husby, MD, PhD  The Annals of Thoracic Surgery  Volume 102, Issue 2, Pages (August 2016) DOI: /j.athoracsur Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Net fluid balance (mL · kg−1 · min−1) before cardiopulmonary bypass (CPB) and at 30-minute intervals during bypass. p Value for within-group effects (pw) = 0.031; p value for between-group effect (pg) = 0.354; p value for interaction (pi) = (B) Fluid extravasation rate (mL · kg−1 · min−1) before CPB and at 30-minute intervals during bypass. pw < ; pg = 0.323; pi = (C) Plasma volume (mL/kg) before and at 30-minute intervals during bypass. Values are mean with standard deviation. pw = 0.001; pg = 0.521; pi = cp < within-group difference compared with pre-CPB values.

(B) Blood pressure measured in aorta before the start of CPB; a typical plot. (C) Blood flow (carotid artery) and blood pressure (aorta) during pulsed CPB perfusion. (D) Blood flow (carotid artery) and blood pressure (aorta) during pulsed CPB perfusion.
