In adult BLS CPR, when should an AED be applied?

• A. Before starting CPR
• B. During CPR and analyze as soon as ready
• C. After finishing CPR
• D. After resuscitation

Answer: (B)

In adult BLS, use the AED during ongoing CPR. You should turn on the AED, apply the pads, and keep chest compressions going while the device analyzes. If the AED advises a shock, deliver it and immediately resume CPR. This approach minimizes interruptions and provides the best chance of survival by combining timely defibrillation with continuous perfusion from compressions. Delaying AED use until after CPR or after resuscitation would miss the critical window for treating a shockable rhythm, and starting CPR after finishing CPR would waste valuable time.
