What is the role of the cardiac chain of survival?

The cardiac chain of survival is a critical concept in the management of cardiac emergencies, specifically cardiac arrest. Its primary role is to improve the chances of survival when a person experiences a cardiac arrest. The chain consists of several interconnected components that, when followed promptly and effectively, can significantly enhance the likelihood of a positive outcome. These components typically include early recognition of cardiac arrest, immediate activation of emergency medical services, early CPR, and early defibrillation, followed by effective advanced life support.

Each link in this chain works synergistically to provide rapid, efficient response and continuous care, which is essential during a cardiac emergency. By focusing on this process, individuals who witness a cardiac arrest can take immediate action, thereby increasing the individual's chance of survival before professional medical help arrives.
