An Automated External Defibrillator (AED) is primarily used to treat ventricular fibrillation, a dangerous heart rhythm that can lead to sudden cardiac arrest.
How an AED Works
An AED is a medical device that serves a crucial role in emergency situations. It performs the following key functions, as outlined in the provided reference:
- Analyzes heart rhythm: The AED first assesses the heart's electrical activity to determine if a dangerous rhythm like ventricular fibrillation is present.
- Delivers an electric shock: If the analysis detects ventricular fibrillation, the AED delivers an electric shock to the heart. This controlled electrical pulse aims to reset the heart's rhythm back to normal.
- Restores normal rhythm: By delivering the electric shock, the AED attempts to end the erratic electrical activity of ventricular fibrillation, allowing the heart to resume its regular, effective pumping action.
When is an AED Needed?
- An AED is specifically designed for situations where a person's heart has stopped beating effectively, often due to ventricular fibrillation.
- It is a crucial tool for treating sudden cardiac arrest.
- AEDs are used by trained professionals as well as by laypersons following easy-to-use instructions.
Understanding Ventricular Fibrillation
Ventricular fibrillation is a chaotic and uncoordinated heart rhythm. Instead of a coordinated pumping action, the heart quivers ineffectively. This rhythm leads to a sudden cardiac arrest, and without prompt intervention, it is fatal.
Practical Insights
- AEDs are designed to be portable and user-friendly so that anyone can use them in an emergency.
- The importance of CPR along with AED is critical. Performing cardiopulmonary resuscitation (CPR) while waiting for the AED and after using it enhances the effectiveness of the defibrillator and increases the chance of saving a person’s life.
- The availability of AEDs in public places like schools, airports, and community centers ensures access to life-saving technology when it is urgently required.
