AED stands for automated external defibrillator.
An automated external defibrillator (AED) is a portable medical device designed to analyze the heart rhythm and, if necessary, deliver an electrical shock (defibrillation) to restore a normal heart rhythm. AEDs are used in cases of sudden cardiac arrest, a life-threatening condition where the heart suddenly stops beating effectively.
Here's a breakdown of what each word in the acronym means:
- Automated: The device is automated because it analyzes the heart rhythm and determines whether a shock is needed, guiding the user through the process with voice prompts.
- External: The AED is external because the electrode pads are placed on the outside of the chest, rather than being implanted.
- Defibrillator: The device is a defibrillator because it delivers a controlled electrical shock to the heart to stop an irregular or rapid heart rhythm and allow the heart's normal rhythm to resume.
AEDs are designed to be used by trained laypersons as well as medical professionals. Their ease of use and portability make them vital in increasing the chances of survival for individuals experiencing sudden cardiac arrest. Many public places, such as airports, schools, and shopping malls, now have AEDs readily available for use in emergencies.
