What is the main purpose of using an AED?

The main purpose of using an AED, or Automated External Defibrillator, is to restore normal heart rhythm during a cardiac arrest. When a person experiences a cardiac arrest, their heart may enter a chaotic rhythm known as ventricular fibrillation, which prevents it from pumping blood effectively. An AED is designed to analyze the heart's rhythm and determine if a shock is needed to restore a normal rhythm. By delivering a controlled electric shock, the AED can help re-establish an effective heartbeat, which is critical for survival in emergency situations involving cardiac arrest. This life-saving intervention is vital, especially when performed promptly, as it can significantly increase the chances of survival until more advanced medical assistance arrives.

While relieving chest pain, increasing blood circulation, and assisting breathing are important aspects of emergency care, they do not relate to the specific function of an AED, which is focused solely on addressing life-threatening heart rhythm abnormalities during cardiac events.
