What’s the first step to use an AED effectively?

The first step to use an AED effectively is to turn on the device and follow the voice prompts. This action initiates the AED's automated process, allowing it to assess the heart rhythm and guide the responder through the necessary steps for effective use. The voice prompts provide essential instructions on when and how to attach the pads, which is crucial for the AED to analyze the heart rhythm properly.

Additionally, activating the AED ensures that it is ready to deliver a shock if needed, and allows the responder to focus on the rescue without missing critical steps or guidance. By following the prompts, you can ensure that you are using the device correctly and efficiently, which is vital when every second counts in a cardiac emergency.

Other actions, such as calling for emergency help or checking for breathing, are also important in an emergency response, but they come after activating the AED in the context of utilizing the device effectively.
