When is it appropriate to use an Automated External Defibrillator (AED)?

The appropriate time to use an Automated External Defibrillator (AED) is when a victim is unresponsive and not breathing normally. This condition indicates that the person may be experiencing a cardiac arrest, where the heart has stopped beating effectively, leading to a lack of blood flow to the brain and other vital organs. In such cases, immediate use of an AED is crucial, as it can analyze the heart's rhythm and provide a shock if necessary, potentially restoring a normal heartbeat and improving the chances of survival.

Using the AED promptly can be a life-saving measure when combined with high-quality CPR, as it increases the likelihood of a successful outcome. Therefore, recognizing the signs of a cardiac emergency—namely unresponsiveness and abnormal breathing—is critical for the timely intervention of using an AED.
