The Chain of Survival is the American Heart Association's framework describing the sequence of time-sensitive actions that give a cardiac arrest victim the best chance of survival. Each link depends on the one before it, and a delay or weakness in any link reduces the overall likelihood of a good outcome.
For out-of-hospital arrest the links are: immediate recognition of cardiac arrest and activation of emergency services, early high-quality CPR, rapid defibrillation with an AED, advanced resuscitation by emergency medical providers, post-cardiac-arrest care, and recovery. The concept underscores why bystander CPR and quick access to an AED matter so much — the first links are often performed by ordinary people, not medical professionals.
