subcutaneous emphysema/tracheal tear

Has anyone known any swimmers with this condition? A friend of mine's 10 year old is currently in the hospital with this. He was told it's a common thing in swimmers (?). I've never even heard of it after 40 years of swimming involvement. He told his mom he felt a pop in his chest at practice the night before last but kept going. I don't know what they were doing but the Valsalva Maneuver seems to be something that can precipitate this occurrence. Wondering if this is also a danger of hypoxic training (though that may or may not be what he was doing at the time). Anyone heard of this?
