  1. MI = myocardial infarction, PVD = peripheral vascular disease, AMI = acute myocardial infarction, PE = pulmonary embolus, OHCA = out-of-hospital cardiac arrest, ROSC = return of spontaneous circulation ECMO = extra corporeal membrane oxygenation
  2. a This includes all types of diabetes mellitus
  3. b Low flow time is the time from commencement of chest compressions to ECMO cannulation
  4. c ROSC is assumed if there is documented evidence of ROSC at any point. This did not have to be sustained
