Question

Quizplus · Accepted Answer

Defibrillation is a critical emergency treatment for ventricular fibrillation, a type of abnormal heart rhythm that can lead to cardiac arrest if not treated promptly. Studies have shown that early defibrillation, within 3-5 minutes of the onset of ventricular fibrillation, can significantly increase the chances of survival. In fact, for every minute that defibrillation is delayed, the chances of survival decrease by 7-10%. Therefore, it is important for trained responders to recognize the signs of cardiac arrest, and to quickly access and use an automated external defibrillator (AED) or other defibrillation equipment as soon as possible.
