------- Forwarded Message I started off programming in the actual stops in ProPlanner as a multi-level dive, but I later decided to throw in the extra conservatism and call it bottom time. With my history of DCS, as long as I continue to be doing decompression dives (I really probably shouldn't), I want to throw in extra conservatism wherever I can. Besides, the time difference isn't all that great - what's 15 or 20 minutes in a lifetime? ...especially if those 15 or 20 minutes can significantly extend one's lifetime. My belief in the value of deep stops is very strong, so I view them as a conservative step to reduce DCS probability. This is what I do and what works for me. Anyone who decides to try the same thing better be ready to handle the responsibility for *whatever* consequences result. Aloha, Rich ------- End of Forwarded Message Hi all, I hesitated a long time, getting sometimes the impression that if you don't do 730 dives a year you shouldn't even read this list ;). Then it is perhaps not the place to discuss personal problems, but on the other hand one learns also by (good or bad) examples. BUT reading the above: >quote what's 15 or 20 minutes in a lifetime? >quote I was doing the following 2 dives on one day: 26 m 20 mins on air, 5 mins decompression @ 3m then 6 hours surface interval, basically eating lobster...(not much wine though: 1/2 glass) then 23 m 25 mins on air, 5 mins decompression @ 3m. The profiles were quite close to rectangular ones. All tables I consulted about the profiles were giving no or only short decompression stops. 5 mins ar so auite a lot of conservatism? On the surface I had a funny fealing, then the left leg got paralised within 5 mins after surfacing. I was given normbaric oxygen, got a warm blanket because I shivered a lot (not really what you should do after a supposed DCI? The blanket I mean, not the shivering.). After less than 30 mins of this (blanket + oxygen), all functionallity of the leg came back. No symptoms were observeable after these 30 mins. The ambulance doc said that it was not a decompression illness, and I got back to diving the day after. 3 months later I went to hospital not only to get the thing sorted out. They did a lot of examinations, among these a magnet-resonnance-spin-tomogramme of the brain (or is there another expression in english??). Well, the doc told me that there was a kind of a shadow in the middle brain caused probably by a small bubble witch was the cause of the paralised leg. No other neurological problems were seen, the ultrasonic exam of the heart gave no indication for a foramen ovale (a hole in the wall, isn't it?). The doc cleared me for diving, saying that it was just 'bad luck'. I don't know if there is really the shadow he mentionned, or if he found what he was looking for not having another explanation. What I think about it now: - put in as much conservatism as you can - sometimes there is good luck or bad luck involved as well, also depending on the individual ( my 3 dive buddies had no problems at all) Any 2 cents? juergen vonhagen@ls*.su*.fr*
