When should a lifeguard use an automated external defibrillator (AED)?

• A. When the victim is conscious
• B. When the victim is unresponsive and not breathing
• C. When the victim shows signs of distress
• D. Only when medical personnel arrive

Answer: (B)

AEDs are intended for someone in cardiac arrest, which appears as the person being unresponsive and not breathing. In that situation, you begin CPR immediately and apply the AED as soon as it’s available. The device will analyze the heart rhythm and advise delivering a shock if the rhythm is shockable. It isn’t used when a person is conscious or just distressed, and you shouldn’t wait for medical personnel to arrive before using it—defibrillation should happen as soon as possible during resuscitation. After the shock is delivered (or if no shock is advised), resume CPR as directed by the device.
