Turn on the AED: Most AEDs have a power button or automatically turn on when the lid is opened. Attach the Pads: Place the adhesive pads on the patient's bare chest as illustrated on the AED or pads themselves. Analyze the Heart Rhythm: The AED will analyze the heart's rhythm and instruct whether a shock is needed. Deliver the Shock: If a shock is advised, ensure no one is touching the patient and press the shock button. Continue CPR: After the shock, continue with CPR until emergency medical services (EMS) arrive or the patient shows signs of recovery.
