What should a rescuer do if the AED advises that a shock is needed?

When an Automated External Defibrillator (AED) indicates that a shock is needed, the rescuer must clear the area and deliver the shock as instructed. This is crucial because the shock is necessary to restore a normal heart rhythm in a person experiencing certain types of cardiac arrest, specifically ventricular fibrillation or pulseless ventricular tachycardia.

Before delivering the shock, it is essential to ensure that no one is touching the patient to prevent injury from the electrical discharge. Clearing the area allows the AED to deliver the shock safely and effectively. After the shock is administered, the rescuer should immediately resume CPR to maximize the chances of survival until advanced medical help arrives.
