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.
