Table 1 The patient characteristics before extracorporeal membrane oxygenation Continuous variables are reported as median (interquartile range) CPR cardiopulmonary resuscitation, ED emergency department, E-CPR extracorporeal cardiopulmonary resuscitation, ECMO extracorporeal membrane oxygenation, BUN blood urea nitrogen, AST aspartate transaminase, ALT alanine transaminase, IABP intraaortic balloon pump, SOFA Sequential Organ Failure Assessment, SAPS II Simplified Acute Physiology Score II *Hypothermia, malignant arrhythmia, dilated cardiomyopathy, ischemic cardiomyopathy, commotio cordis, abdominal aortic aneurysm rupture † Door to ECMO time: the time from arrival at the ED to ECMO implantation ‡ Hypoxic brain damage, hemothorax, pulmonary hemorrhage, chest wall compartment syndrome, chylothorax The characteristics of survivors and non-survivors during extracorporeal membrane oxygenation support a Fisher’s exact test.
