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

The 5 links in the adult Chain of Survival are

• Immediate recognition of cardiac arrest and activation of the emergency response system

• Early cardiopulmonary resuscitation (CPR) with an emphasis on chest compressions

• Rapid defibrillation

• Effective advanced life support

• Integrated post-cardiac arrest care


A strong Chain of Survival can improve chances of survival and recovery for victims of heart attack, stroke and other emergencies.
