I recently watched a tv show where Navy divers after a long dive would theoretically have to do a 2 to 3 hour stop at fourty feet, but they don't the water is too cold and what not, instead they surface with no stops and in less than five minutes get unsuited and go in a chamber to decompress at 40f. Which is normal practice for that kind of diver.
My question is, why do most diving manuals suggest that if a mistake was done, take the diver to the clossest chamber and put him on o2. Why not if the mistake was identified early (Emergency Ascent) just grab a new bottle and reg and go back down to i don't know 36f or 40f if not only 30, stay there for 10 to 15mn (considering the dive wasn't supposed to be a decompression dive) and then ascend and just monitor the diver, even then bring him to a chamber. At least the bigger bubles would have, due to the pressure, gotten smaller and with the prolongued stay would have had time to exite the blood stream or the tissue.
Or am i completly missing something? i honestly don't understand. I do know that a lot of what if's would have to come into play, and maybe that's why they don't say you can do it... it would have to be under 5mn, a no deco dive etc...
If anybody can help?
