What are the steps in the Cardiac Chain for Survival?

The Cardiac Chain of Survival outlines critical steps that significantly improve the chances of survival for individuals experiencing a cardiac emergency. The correct answer highlights four essential steps: early recognition of cardiac arrest, early activation of the emergency medical services (EMS), early CPR by bystanders, and early use of an Automated External Defibrillator (AED).

Early recognition is crucial as it prompts immediate action, ensuring that the person in distress receives prompt assistance, which can make a significant difference in their chances of survival. Following this, activating EMS ensures that advanced medical care is on its way without delay. Starting CPR as soon as possible helps maintain blood flow to vital organs until professional help arrives, while the use of an AED can restore a normal heart rhythm if the patient is experiencing a shockable rhythm.

In contrast, other options do not correctly enumerate the established and tested steps in the Cardiac Chain of Survival. They may include components that are part of emergency response but do not emphasize the sequence and importance of early intervention in improving outcomes during cardiac emergencies.
