When should a rescuer deliver shock with aed?

A rescuer should use an automated external defibrillator device in the context of suspected sudden cardiac arrest in the following instances of analyzing its rhythm:

1. Shock Advised: AED analyzes heartbeat as shockable rhythm (Ventricular Fibrillation/Ventricular Tachycardia).

2. No Shock Recommended: The AED recognizes a rhythm that does not warrant immediate defibrillation and encourages hands-only CPR.
