Which statement about AED pad placement is correct?

• A. Pads must contact bare dry skin.
• B. Pads may be placed over clothing.
• C. Pads must be placed on the back.
• D. Pads can be placed on wet skin.

Answer: (A)

Good pad contact with clean, dry skin is essential for effective defibrillation. When the pads sit directly on bare dry skin, the electrical current can pass through the chest with minimal impedance, delivering the shock where it’s needed. If clothing covers the chest, it should be removed or cut away so the pads can contact skin, and the area should be wiped dry if it’s sweaty or wet. If chest hair prevents full contact, it’s appropriate to shave the area so the pads seal properly. Placing pads over clothing creates an insulating layer that increases impedance and can prevent the energy from delivering effectively. Placing pads on wet skin or over moisture can also disrupt conduction and increase the risk of burns or ineffective shock. So the best practice is pads contacting bare dry skin.
