Every so often an interesting question arises in regard to scuba diving and I run it by a few people to see if they can get it right. I may add more to this thread depending on how it goes that's why I didn't make a poll out of the one question it's more of a discussion thread.
Here's one that's been circulating on a FaceBook scuba group.
You're in a car that goes off the road and you sink in, say 50' of water. The windows are closed or mostly closed and the car is rapidly filling with water. You take a deep breath of air that remains in the vehicle, exit the car and swim for the surface.
The question- If you don't exhale on the way up are you at risk for type DCS (ruptured lung and arterial gas embolism).
