    Someone on this thread told that holding a breath while descending was dangerous to experienced SP's before.

    That's an interesting question. Intrathoracic pressure would be pretty consistent, not like inspiration/expiration on the surface, and even with incomplete inspiration the lungs would probably not be compressed to anywhere near residual volume at that depth, so I don't think that snorkeling would carry any greater risk than exercise on the surface. Even with a 100% pneumo at depth, the air in the pleural space would only expand to the volume it would have been had the individual suffered a 100% pneumo on the surface. Not to say that that wouldn't be incapacitating, but it doesn't have the potential for cardiac tamponade like a pneumo while scuba diving does.

    Best regards,
