What is an AED?

An AED, or Automated External Defibrillator, is specifically designed for use by laypersons as well as emergency responders in critical situations where someone is experiencing sudden cardiac arrest. It provides clear and concise voice prompts or visual instructions to guide users through the defibrillation process, making it accessible for individuals who may not have medical training. AEDs are equipped with built-in sensors that can analyze a patient's heart rhythm and determine if a shock is necessary, ensuring that they are safe and effective for use in public spaces.

In contrast, the other choices describe medical devices that cater to different audiences or have different functions. For instance, a monitor-defibrillator is a more complex device that healthcare professionals use, often requiring specialized training to operate. An implanted defibrillator is a device surgically placed inside a patient, designed to automatically detect and correct heart rhythm issues without any intervention from bystanders. Additionally, cardiac monitors and defibrillators intended for healthcare professionals have sophisticated monitoring capabilities and are not suited for use by those without extensive training. This distinction is vital, as it highlights the AED's unique role in empowering the public to respond effectively in emergencies.
