You should put a tip in for the Dead Pool. The only other person who ever won did so by betting on someone who was clearly terminal. I think you're in for a good shot because the reason people deteriorate after ventilation is because the ventilation process is harmful. It is used as a last resort because it can easily do more harm than good. If you get put on one, you will be lucky to pull through, especially if you are one of these at risk demographics.
