Fig. 1 — Myocardial perfusion during mechanical ventilation with limited peak inspiratory pressure targeting permissive respiratory acidosis and increased peak inspiratory pressure targeting normal pH. Panel a: left ventricle - subendocardial myocardium; panel b: left ventricle - subepicardial myocardium; panel c: left ventricle - ratio of subendocardial to subendocardial perfusion; panel d: right ventricle - subendocardial myocardium; panel e: right ventricle - subepicardial myocardium; panel f: right ventricle - ratio of subendocardial to subendocardial perfusion; Boxes are median and 25/75 percentile, whiskers are 5/95% percentile. * p < 0.05 compared with increased P_AW; ** p < 0.01 compared with increased P_AW
