Ok, say right now you discovered you had a pfo. Maybe you've been bent in the past, maybe not, but you're obviously in love with diving and still alive. so what would you do? What can you expect these theoretical divers (statistically, including a significant fraction of ourselves) to do? Do you want them to stop diving? Use another table? Stop thinking about these theoretical divers and ask yourself what you would do. A significant number of you reading this have this problem. I haven't been checked. I don't know if I have one. If it's normally closed, I continue diving converatively, and try not to sneeze. I already clear my ears by moving my jaw, not Valsalva, so it may not open. I'm a normal diver. Do I use a less conservative table now? nope. If I have a huge gaping hole in my heart, I guess I start coming up even slower. But I haven't been bent yet, so I guess I do what I've been doing and don't get sloppy. I already worry about the wide grey line between silent bubbles and silent neurological DCS. So do I use another table? Maybe. Do I buy the interface for my Nemesis and tell it to be more conservative? Probably. Watch the loading bars on the interface and use O2? maybe. Don't rally mean to start another thread here, but theoretically, I'm talking to a lot of us when I say "you have this problem, what are you doing?" just food for thought. --------------------------------------Mars needs women. ======================================================= Roger Carlson w 310-812-0430 somewhere off Hermosa Beach, CA f 310-812-1363 roger@ch*.sp*.tr*.co* h 310-frogger =======================================================
