When using an Automated External Defibrillator (AED), what is the first step before applying pads?

The first step before applying pads when using an Automated External Defibrillator (AED) is to turn on the AED and follow the voice prompts. This is crucial because the AED will provide specific instructions and ensure that you are using the device correctly. When the AED powers on, it typically begins to assess the patient's heart rhythm and will guide you through each step of the process, including when to apply the pads and advise whether a shock is needed.

Following the audio and visual prompts helps ensure that every necessary action is performed in the correct sequence. Furthermore, modern AEDs are designed to be user-friendly and to assist even those with minimal training, highlighting the importance of activating the unit before any physical actions are taken with the patient. Bystanders and surrounding individuals may also need to be cleared only if instructed to do so by the AED or based on the situation, making it important to prioritize following the AED's guidance first.
