Success Rate of CPR

The success rate of CPR is quite complicated. Nonetheless we have some interesting facts.

  1. Overall survival from OHCA has been stable for almost 30 years
  2. The aggregate survival rate, is between 6.7% and 8.4%
  3. 5% of patients resuscitated with conventional CPR and more than 20% of those resuscitated with extracorporeal CPR were diagnosed with brain death
  4. OHCA victims who receive CPR from a bystander or an EMS provider are much more likely to survive than those who do not
  5. The most powerful criterion associated with survival from OHCA is ROSC in the field. Failure to restore a pulse on scene indicates that the patient will not likely survive to hospital discharge, irrespective of the subsequent sophistication of in-hospital care

Recusal

Recusal motions for judicial bias were unknown at common law in England, and none would exist in federal courts until 1911. There was no standard of appearance of partiality, and none would exist in federal courts until 1974.
