What should you do when an AED arrives?

When an AED (Automated External Defibrillator) arrives, the most important action to take is to turn it on and follow the provided directions. This is crucial because the AED is designed to guide the user through each step of the emergency response process. By turning it on, the device will start providing instructions through voice prompts that are easy to follow, even for someone who has not been trained in advanced medical care. The timely use of an AED can significantly increase the chances of survival for a person experiencing a cardiac arrest, making immediate activation essential.

While other options may seem relevant to the context of AED use or emergency medical situations, they do not address the immediate need for action in a cardiac emergency. Storing the AED in a locked cabinet would prevent timely access in an emergency, notifying emergency services is important but should occur simultaneously with using the AED, and testing the battery or checking expiry dates are routine checks, not actions needed during an acute emergency.
