The Chain of Survival

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

The 5 links in the out-of-hospital Chain of Survival are:

  1. Recognition of cardiac arrest and activation of the emergency response system
  2. Early cardiopulmonary resuscitation (CPR) with an emphasis on chest compressions
  3. Rapid defibrillation
  4. Basic and advanced emergency medical services
  5. Advanced life support and post-cardiac arrest care
