Chain of survival
Chain of Survival
The Chain of Survival (pronunciation: /ʧeɪn ɒv səˈvaɪvəl/) is a sequence of steps that, when properly executed in a timely manner, maximize the likelihood of survival following cardiac arrest.
Etymology
The term "Chain of Survival" was coined by the American Heart Association (AHA) to describe a series of critical actions that, when performed sequentially, can significantly improve the chances of survival for someone experiencing a cardiac arrest.
Steps of the Chain of Survival
The Chain of Survival consists of four or five links, depending on the model used:
- Early Access: The process begins with recognizing the signs of cardiac arrest and calling for emergency medical services.
- Early CPR: This step involves performing cardiopulmonary resuscitation (CPR) to the victim as soon as possible.
- Early Defibrillation: The third link is the delivery of an electric shock to the heart using a defibrillator.
- Early Advanced Care: This involves the arrival of trained healthcare providers who can provide advanced life support.
- Post-Cardiac Arrest Care: Some models include a fifth link, which involves the care given to the patient after the return of spontaneous circulation (ROSC).
Related Terms
- Cardiac Arrest: A sudden loss of blood flow resulting from the failure of the heart to pump effectively.
- Cardiopulmonary Resuscitation (CPR): An emergency procedure that combines chest compressions often with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
- Defibrillator: A device that delivers a dose of electric current to the heart to help it regain a normal rhythm.
- American Heart Association (AHA): A non-profit organization in the United States that fosters appropriate cardiac care in an effort to reduce disability and deaths caused by cardiovascular disease and stroke.
