Where should AED pads be placed on an adult's chest?

The proper placement of AED pads on an adult's chest is crucial for the effective delivery of a shock during a cardiac emergency. The pads should be positioned to maximize the path of electricity through the heart, which is typically done by placing one pad on the upper right side of the chest, just below the collarbone, and the other pad on the lower left side, on the ribcage. This placement creates an effective electrical circuit that increases the chances of successfully resetting the heart's rhythm in cases of ventricular fibrillation or pulseless ventricular tachycardia.

This arrangement on the right and left sides is foundational in CPR and first response training, ensuring that rescuers maintain a systematic approach when using an AED. Understanding this can help rescuers act quickly and correctly during emergencies.
