Pain and shock.
allow the victim to assume the position easiest for breathing, and observe/treat for shock.
Possibility of shock.
So the electric currents from the AED do not transfer from the victim to yourself, thus, you yourself becoming a victim of shock if exposed to the currents.
You should not move the victim except as necessary. The person should not be given anything to eat or drink. You should watch for signs of shock and locate a proper medical facility as quickly as possible. Loss of fluids can be treated by IV where available.
Insure there is no pulse before you attach the pads to the victim.
The person touching the victim will also receive an electric shock (not as powerful as the victim but a shock none the less).
If you touch the victim while an AED is delivering a shock, you too will receive a shock.
So no other person but the victim gets the shock.
