What does AED stand for?

The term AED stands for Automated External Defibrillator. This device is designed to be used in emergency situations where a person is experiencing sudden cardiac arrest. The automated aspect of AEDs means that they can analyze the heart's rhythm and determine if a shock is needed to restore a normal heartbeat. They are external in that they are used on the patient's chest, typically by bystanders who may not be trained medical professionals.

Understanding the context behind the name is crucial for identifying the appropriate use of these devices in life-threatening scenarios. AEDs are user-friendly and often come with audio and visual prompts, guiding users throughout the process of delivering a shock if necessary. This accessibility makes them invaluable in public spaces, allowing rapid response during emergencies.
