3 Fig 2 Schematic image of the extracorporeal membrane oxygenation ECMO circuit. (LMT = left main trunk coronary artery; lt. = left.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Sample waveforms at each driving mode. (AoP = aortic pressure; CoF = coronary arterial flow; ECG = electrocardiogram; IABP = intraaortic balloon pump; LVP = left ventricular pressure; PAP = pulmonary artery pressure; RF = renal arterial blood flow; RS = rotational speed.)
