Chain of Survival
The Chain of Survival
The Chain of Survival is there to show that the sooner certain actions are taken, the more chance of survival a patient who goes into (or might go into) cardiac arrest has.
1) Early Recognition and Call for Help
The sooner it is recognized that someone might go into cardiac arrest from a serious heart problem, and the sooner help is called, the more the chances of preventing cardiac arrest are.
2) Early CPR
If someone does go into cardiac arrest, immediate CardioPulmonary Resuscitation (CPR) will buy time till an Automated External Defibrillator (AED) to shock the heart arrives.
3) Early Defibrillation
The sooner the heart is shocked by an AED (Automated External Defibrillator), the better the chances of survival for the patient. Every minute that is lost costs about 10% of life chance. But shocking will not be effective if the patient’s heart is in a 'non-shockable’ rythm.
4) Early Advanced Care
The cause of the cardiac arrest still remains, and the patient will have to be given advanced cardiac life support in order to survive.
