When should an AED be used?

An AED, or Automated External Defibrillator, should be used when a person is unresponsive and not breathing normally. This scenario indicates a potential cardiac arrest, where the heart is not pumping effectively, and timely defibrillation can significantly increase the chances of survival.

The AED is designed to analyze the heart's rhythm and deliver a shock if necessary, which can restore a normal heartbeat during critical moments. Using an AED promptly can greatly improve outcomes in cases of sudden cardiac arrest, making it a vital tool in emergency response.

In contrast, a person who is standing and talking is clearly responsive and likely not in a critical situation that warrants an AED. Similarly, someone experiencing a headache or chest pain may require medical attention but does not necessarily need immediate defibrillation unless they meet the criteria of being unresponsive and not breathing normally.
