How should an AED be properly used?

The appropriate use of an Automated External Defibrillator (AED) is to turn it on first, then attach the pads, and follow the prompts provided by the device. This sequence is vital for several reasons. First, turning on the AED activates its internal mechanisms and prompts the user with voice instructions that guide the responder through the entire process of treating a patient in cardiac arrest. These prompts can include when to attach the pads, when to analyze the heart rhythm, and when to deliver a shock if necessary.

By following this method, you ensure that the AED is analyzing the patient’s heart rhythm as soon as its pads are properly positioned, allowing for timely intervention. This is particularly critical since every second counts in a cardiac emergency, and immediate use of the AED can significantly increase the victim's chances of survival.

Using the AED only when there are multiple victims or delaying its activation until checking certifications can lead to a critical loss of time, which improves the chances of a positive outcome in cardiac arrest situations. Additionally, attaching the pads before turning on the device could result in missing important instructions and analysis that the AED provides, potentially leading to ineffective or missed treatment.
