What is the correct technique for using an AED?

Using an Automated External Defibrillator (AED) correctly is crucial for effectively responding to a cardiac emergency. The correct technique involves turning on the device first, which activates its voice prompts that guide the user through the process. After turning it on, the pads must be attached to the victim's bare chest to ensure proper adhesion and optimal conductivity. Following the voice prompts is essential, as they instruct the user on whether a shock is indicated and when to press the shock button.

By attaching the pads directly to the skin, you ensure that the electrical currents can flow effectively across the heart, maximizing the chances of returning a normal heart rhythm. The AED assesses the heart rhythm and advises the user on the necessary steps, which underscores the importance of following its prompts.

In contrast, turning the AED off before use would prevent it from providing necessary instructions, while waiting for 5 minutes of CPR before using the AED may result in a delay that could compromise the victim's chances of survival. Dressing the pads over clothing significantly undermines the AED's effectiveness, as it can impede electrical conduction and increase the risk of an ineffective shock. Hence, following the outlined procedure ensures the best chance of a successful intervention.
