How quickly should defibrillation be performed after the onset of cardiac arrest?

Defibrillation is a critical intervention that must be performed as soon as possible after the onset of cardiac arrest, especially in cases of ventricular fibrillation or pulseless ventricular tachycardia. The sooner defibrillation is delivered, the higher the chances of restoring a normal heart rhythm and improving survival rates. Research indicates that for every minute that passes without defibrillation, the likelihood of survival decreases significantly, emphasizing the urgency of this life-saving procedure.

Responding immediately to cardiac arrest with defibrillation maximizes the potential benefits, as the heart's ability to regain an effective rhythm diminishes over time. Therefore, emphasizing "as soon as possible" underscores the importance of prompt action in emergency situations to enhance patient outcomes.
