The Chain of Survival
Early Intervention Saves Lives
The chain of survival is a representation of basic management of emergency cardiac events.
The best chance a person has of surviving an out-of-hospital cardiac arrest is if the following sequence of emergency care can be initiated as quickly as possible.
Recognising the emergency and calling 999 for an ambulance as quickly as possible
Carrying out CPR delivers oxygen to the heart, brain and other vital organs to prevent the patient from becoming hypoxic (lack of oxygen to the tissues, which causes them to start dying).
Use of a defibrillator to deliver an electric shock to the heart in an attempt to restore normal sinus rhythm
Early Advanced Life Support
Intensive care facilities and a range of life saving drugs can be given in hospital and, in some cases, out in public
