Success Rate of CPR
The success rate of CPR is quite complicated. Nonetheless we have some interesting facts.
- Overall survival from OHCA has been stable for almost 30 years
- The aggregate survival rate, is between 6.7% and 8.4%
- 5% of patients resuscitated with conventional CPR and more than 20% of those resuscitated with extracorporeal CPR were diagnosed with brain death
- OHCA victims who receive CPR from a bystander or an EMS provider are much more likely to survive than those who do not
- 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
