How do you use an AED?

Using an AED (Automated External Defibrillator) is a critical intervention for someone experiencing a cardiac arrest, and the correct procedure involves a few essential steps. The first step is to turn on the device, as this activates the voice prompts and visual signals that guide the user through the process. Following these prompts is crucial because they provide real-time instructions tailored to the situation, making it easier for someone who may not be trained in advanced life support to assist effectively.

After turning on the AED, the next step is to attach the pads to the bare skin of the person in cardiac arrest. This is vital because the pads are designed to deliver a shock to the heart if needed. Proper placement of the pads is necessary for the AED to analyze the heart's rhythm correctly and determine whether a shock is required.

The other options present scenarios that are not only less effective but potentially dangerous. For instance, attaching pads first without turning on the AED means the user would miss out on crucial instructional prompts that guide them through the procedures. Also, waiting for a person to be conscious before using the AED contradicts its purpose since AEDs are specifically for individuals who are unresponsive and not breathing normally. Lastly, delaying the use of an AED until paramedics arrive could
