Out-of-hospital Chain of Survival

The term Chain of Survival provides a useful metaphor for the elements of the ECC systems concept.

The 6 links in the adult out-of-hospital Chain of Survival are:

Recognition of cardiac arrest and activation of the emergency response system
Early cardiopulmonary resuscitation (CPR) with an emphasis on chest compressions
Rapid defibrillation
Advanced resuscitation by Emergency Medical Services and other healthcare providers
Post-cardiac arrest care
Recovery (including additional treatment, observation, rehabilitation, and psychological support)

A strong Chain of Survival can improve chances of survival and recovery for victims of cardiac arrest.
