What is the protocol for using an emergency medical device, such as an AED?

Following the device's prompts and guidelines for use on a patient is crucial because automated external defibrillators (AEDs) are designed to be user-friendly and provide step-by-step instructions to assist the rescuer during a critical situation. These prompts ensure that the operator delivers the appropriate actions at the right time, which includes assessing the patient's heart rhythm and administering a shock if necessary. AEDs often include visual and audible cues to guide the rescuer, which can help reduce confusion and streamline the resuscitation efforts.

Using an AED effectively can greatly increase a patient’s chance of survival in cases of sudden cardiac arrest, as these devices are specifically engineered for emergency situations. It's imperative that rescuers adhere to the guidance provided by the AED to ensure proper and safe use.
