What is the Chain of Survival?

The Chain of Survival describes a sequence of steps that together maximise the chance of survival following cardiac arrest.

  • The first link in the chain is the immediate recognition of cardiac arrest and calling for help.
  • The second is the prompt initiation of CPR.
  • The third is performing defibrillation as soon as possible.
  • The fourth is optimal post resuscitation care. 

Like any chain, it is only as strong as its weakest link. If one stage is weak, the chances of successful resuscitation are compromised.
