Ok. I'm not that familiar with the physiology of a whale.

I do know that the bends are related to gas expansion and not contraction.

The air molecules are compressed by the pressure, and lungs are very elastic.

I'm not sure where you expect the air to get squeezed out to.

No.

Divers get the bends because they breathe air under pressure and excess nitrogen absorbed by the body is released as bubbles in the the blood stream if the diver ascends too quickly.

Whales breathe air at the surface and therefore the air is not under pressure. (well technically it is at 1 Atmosphere (Atm))
