What do you do with defibrillator first?

When using a defibrillator, the first step is to ensure the scene is safe for both the rescuer and the victim. Next, turn on the defibrillator and follow the audible or visual prompts provided by the device. Attach the pads to the patient's bare chest as indicated, ensuring they are placed correctly, and then allow the defibrillator to analyze the heart rhythm. If a shock is advised, ensure no one is touching the patient and press the shock button.
