In CPR, what does the term 'chains of survival' refer to?

The term 'chains of survival' refers to the series of steps that should be followed in emergency situations to enhance the chances of survival for victims of cardiac arrest and other life-threatening events. This concept is crucial in CPR training because it outlines the critical actions that need to be taken—such as recognizing the emergency, calling for help, performing CPR, and using an automated external defibrillator (AED) when available. These steps are designed to work together in a systematic way to improve outcomes for individuals who experience a cardiac event.

Understanding the 'chains of survival' emphasizes the importance of timely and effective intervention, which can significantly impact a victim's chance of survival and recovery. Each link in the chain represents a necessary action that builds upon the previous one, illustrating how interconnected and essential each step is in responding to an emergency.
