Fig 1 Variables significantly related to odds for developing mild vasoplegia. (ACE = angiotensin-converting enzyme; Afib = atrial fibrillation; CI = confidence interval; CPB = cardiopulmonary bypass; FFP = fresh-frozen plasma; HCT = hematocrit (%); LVF* = left ventricular function—normal-mild vs moderate-severe; OR = odds ratio).

Fig 2 (A) Probability in unadjusted odds ratios (OR) of developing mild vasoplegia by number of red blood cells (RBC) transfused. (B) Risk-adjusted probability in odds ratios (OR) of developing mild vasoplegia by number of red blood cell (RBC) units transfused in an intermediate risk patient as calculated for a 70-year-old man with diabetes, history of atrial fibrillation and myocardial infarction, no hypertension, no endocarditis, moderate-severe left ventricular function on preoperative angiotensin-converting enzyme inhibitors, no calcium channel blockers, creatinine (1.4 mg/dL), cardiopulmonary bypass duration of 90 minutes, hematocrit of 30, who receives a transfusion of fresh frozen plasma and platelets.

Fig 3 Perioperative variables significantly related to the odds of developing profound vasoplegia. (Afib = atrial fibrillation; CI = confidence interval; CPB = cardiopulmonary bypass; FFP = fresh frozen plasma; HCT = hematocrit (%); LVF* = left ventricular function—normal-mild vs moderate-severe; OR = odds ratio; RBC = red blood cells.)
