What element is essential to evaluate before placing AED pads on a victim?

Evaluating the presence of water near a victim is crucial before placing AED pads due to safety concerns related to electrical conductivity. Water is a conductor of electricity, and if the area is wet or the individual is in contact with water, there is a risk of electrical shock to both the victim and the rescuer when the AED is activated. Keeping the victim and AED pads clear of water ensures that the electrical shock delivered by the AED can travel effectively to the heart without the risk of diverting the current or causing harm to bystanders.

Considering other factors like the age of the victim, the type of clothing, or the presence of a crowd may be important in different contexts, but they do not pose immediate and critical safety risks associated with the use of an AED. Thus, focusing on the surrounding environment and ensuring it is safe from water is paramount to effective and safe defibrillation.
