What is the first step in the survival chain?

The first step in the survival chain focuses on recognizing the signs of a cardiac arrest and initiating Cardiopulmonary Resuscitation (CPR). This step is crucial because timely recognition and action can significantly impact the victim's chances of survival. When a person experiences cardiac arrest, immediate intervention is essential.

By recognizing the emergency, a bystander can assess the situation and begin CPR, which helps maintain blood flow to vital organs until advanced medical help arrives. This early action is what precedes any subsequent steps, such as calling for assistance, using an Automated External Defibrillator (AED), or providing post-cardiac care. Each of these subsequent measures relies on the initial recognition and response to effectively address the cardiac emergency.
