When applying AED pads, they must contact which type of skin?

• A. Hairy Skin
• B. Wet Skin
• C. Through Clothing
• D. Bare Dry Skin

Answer: (D)

Delivering an effective shock requires good electrical contact with the skin. Bare dry skin minimizes resistance, allowing the pad gel to seal firmly and the electrical current to flow directly into the chest with minimal impedance. Hair in the pad area can prevent a proper seal, reducing contact even if the pad is pressed down. Wet skin or moisture increases unpredictable current flow and can raise the risk of skin burns or ineffective defibrillation. Placing pads over clothing adds an insulating layer, which raises impedance and decreases the amount of current reaching the heart. So, pads work best on bare dry skin.
