Just a thought...

Most marine mammals actually collapse their lungs when they go underwater.
This prevents the problems with resurfacing such as gas expansion or gas
coming out of solution. What if a bioware or cyberware structure could be
developed to do this.

BTW, humans can't do this - collapsing the lungs for a human has disastrous
effects. We're not very good at reinflating them. I know someone is going to
mention babies breathing once they born. But, I'm referring to both the
physical processes referring to the lungs as well as the lack of stimulus
from the nervous system!
