If an AED detects ventricular fibrillation, what is the next step?

The correct answer is to follow the AED prompts. When an Automated External Defibrillator (AED) detects ventricular fibrillation, it will guide the user through the necessary steps to provide care to the victim. The AED is designed to analyze the heart rhythm and determine whether a shock is needed.

Following the prompts is crucial because the AED provides specific instructions on whether to deliver a shock, prompts for CPR, and in what sequence these actions should occur. This systematic approach is essential for effective intervention, as it ensures that the responder takes appropriate action based on real-time feedback from the device.

While performing CPR and checking for a pulse are important components of emergency care, they should be done in accordance with the AED's instructions. The AED will typically advise you to start CPR after delivering a shock or if no shock is advised, thereby optimizing the victim's chances of survival. Immediate shock without following the prompts might lead to incorrect application or missed critical steps that the AED is programmed to guide you through.
