What is considered the first link of survival in cardiac arrest situations?

In cardiac arrest situations, the first link of survival emphasizes the importance of prevention. This foundational step addresses factors that might contribute to cardiac arrest, such as managing risk factors (like obesity or smoking), recognizing early signs of cardiac distress, and seeking timely medical intervention. By focusing on prevention, individuals and communities can potentially reduce the incidence of cardiac events and increase overall survival rates. This proactive approach sets the stage for effective responses should a cardiac arrest occur.

While other links in the chain of survival, such as CPR, emergency response activation, and defibrillation, are critical to addressing an active cardiac arrest situation, they rely on the understanding that reducing the number of cardiac arrests in the first place is the most effective strategy. Hence, prevention is the key first link that underpins the entire survival chain.
