If a diver will have at depth more air in the lungs than his TLC at the surface than expension could be harmful if air isn't exhaled.
It all depends on the specific case (that can be represented in simple math but I don't see the point).
Except in a case of a trapped/tied person I can't see any reason to perform CPR/EAR underwater, especially as it'll delay that person's arrival to the surface.
