This is not as complex as it might initially seem.

First, the victim should not be IN the water when you use the AED - and I don't care whether that's in a swimming pool or lying on the deck surrounding the pool in an eighth of an inch of water.

Second, the skin in the area of the upper body needs to be dried off, if wet. if the skin is wet, a more-than-usual amount of electrical energy will be diverted from the normal path through the heart to a path along the skin.
