What to tell people when using an automated defilatator?

When using an automated external defibrillator (AED), calmly instruct bystanders to call emergency services and ensure the area is clear. Follow the AED's voice prompts carefully, placing the pads on the patient's bare chest as indicated. Advise everyone to stand clear while the device analyzes the heart rhythm, and deliver a shock only if prompted. Reassure the crowd that help is on the way and continue CPR if necessary until emergency responders arrive.
