- Bill, in my Nitrox course, we were taught almost exactly the opposite.
- Yes, there are a string of different symptoms which accompany O2 toxicity,
- and people who have suffered from this and survived it report having most,
- if not all, of the symptoms. The scarry part is that the majority (apparently)
- reported having the symptoms in a quick succession (like a second or two).
- Not enough time in which to react.
-
- The moral? If you think you might detect even one symptom, get to a more
- shallow depth immediately. Don't wonder, or ponder the symptom, move!
- Think about it after the dive. (But that was basically Bill's moral as well.)
