<font color='#0000FF'>Well when I see someone with a pneumothorax (burst lung) I just stick a chest drain in

No surgery required unless they have a bronchopleural fistula, which you won't know until after the chest drain is in anyway.
I'm not a hyperbaric medicine doctor, but I cant see how having a chest drain in would prevent recompression - as the air in the pleural space expands it bubbles out of the drain. Of course if any of our hyperbaric chamber operatives know different, I will stand corrected.
