When should you use an AED in on-field cardiac arrest?

• A. Wait for EMS to arrive before using AED.
• B. Use the AED only after several minutes of CPR.
• C. Use the AED as soon as available.
• D. Use a manual defibrillator first and ignore AED.

Answer: (C)

Early defibrillation saves lives in cardiac arrest. An AED analyzes the heart rhythm and tells you if a shock is needed, so delivering it as soon as possible gives the best chance of restoring a perfusing rhythm. In an on-field setting, use the AED as soon as it’s available. Don’t wait for EMS to arrive before shocking if the device indicates a shock. Start CPR immediately and continue while someone gets the AED and applies it. After turning it on, place the pads, follow the prompts, and deliver a shock only if advised, then resume CPR right away. This approach combines immediate defibrillation with continuous chest compressions, which maximizes survival chances. Using a manual defibrillator first and ignoring the AED isn’t appropriate in most on-field scenarios since the AED provides clear, user-friendly guidance for rescuers who may not be trained to operate a manual device.
