Which of the following components is part of an automated external defibrillator (AED)?

An automated external defibrillator (AED) is a portable electronic device that automatically diagnoses life-threatening cardiac arrhythmias and can treat them through defibrillation. One of the key features of an AED is its user-friendly design, which often includes voice prompts to guide the user through the process of delivering a shock and performing CPR, if necessary. This feature is crucial because it allows individuals with little to no medical training to use the device confidently, promoting quick and effective intervention in emergencies.

The presence of voice prompts enhances the accessibility of AEDs, making them suitable for use in a variety of settings, such as workplaces, schools, and public places where trained medical personnel may not be immediately available. These prompts help ensure that the correct steps are followed, which can significantly improve the chances of survival for a victim of sudden cardiac arrest.

While other components like manual modes for professionals, charging capacitors, and display screens can be associated with various defibrillator models, they may not be standard features in all AEDs. Voice prompts, however, are a defining characteristic of AEDs, aimed at increasing the chances of effective use during critical moments.
