CPR is a critical step in the AHA’s Chain of Survival. The term Chain of Survival provides a useful metaphor for the elements of the ECC systems concept.
The 5 links in the adult out-of-hospital Chain of Survival are:
- Recognition of cardiac arrest and activation of the emergency response system (calling 9-1-1 in the US)
- Early CPR with an emphasis on chest compressions
- Rapid defibrillation
- Basic and advanced emergency medical services
- Advanced life support and post-cardiac arrest care
A strong Chain of Survival can improve chances of survival and recovery for victims of cardiac arrest.
