The Chain of Survival.
The series of actions linking the victim of sudden cardiac arrest with survival are called the "Chain of Survival".
- Early recognising those at risk of cardiac arrest and calling for help in the hope that early treatment can prevent arrest.
- Early Cardiopulmonary resuscitation (CPR) to buy time,performing chest-compression-only CPR is better than giving no CPR at all (1)(2) , CPR should be provided immediately after collapse of the patient (3)(4) , Properly performed CPR can keep the heart in a shockable ventricular fibrillation for 10–12 minutes longer (5) ,CPR keeps blood flowing to the heart, brain and throughout the body, sustaining life until a defibrillator, or other advanced medical care, arrives.
- Early defibrillation, to restart the heart,this step is often called the critical link in the Chain of Survival, because treatment with an automated external defibrillator(AED) can restore a normal beat to a heart quivering from SCA by delivering a measured electrical shock.
- Post-resuscitation care: to restore the quality of life
