The insides of submarines are at roughly 1 BAR. Unless there is a breach of the integrity of the submarine and you manage to stay in a compressed air pocket for a sustained amount of time (unlikely, at best) prior to ascent, you will not have gas disolved into your tissues and thus won't get bent.

No, but 1 bar air in your lungs can be quite a proposition at any significant depth. Not for the faint of heart.

  Can you clarify what you mean by this? As I type this comment, I have about that density of air in my lungs, and it doesn't particularly trouble me.

    One atmosphere in your lungs, ten atmospheres outside your lungs --> scrunch. For an approximate simulation, imagine what removing 90% of the air from your lungs might feel like.

      That's not how flexible containers work. In the presence of increased pressure, the guts press against the diaphragm, which compresses the lungs. I don't have to imagine what removing air from my lungs feels like: that is part of breathing! Anyway, this guy seems to do OK compressing his lungs even more: http://competition.the-french-job.com/spread-the-world-record/ http://competition.the-french-job.com/spread-the-world-recor...

        If the increased pressure is high enough, your diaphragm and lungs are going to be in a world of hurt. Physiological freaks aside, go too deep, and you're dead. Especially when you go from 1 bar to, say, 15 instantly, which is a situation that free divers do not expose themselves to.

        It's not just your lungs though... You know that pain you get in your sinuses and ears and other air-pockets in your body when you swim to the bottom of the deep-end of the pool? That's from a pressure difference of like .3 bar. Now imagine something 10 times that.

    If your lungs contain 1 bar, and water around you is 10 bar, you will be very uncomfortable.
