Helium may be used as a substitute for nitrogen to dilute oxygen for deep water diving. It is colorless, odorless, tasteless, and chemically inert. However, it is more expensive than nitrogen and drains body heat from a diver.
When a diver returns to a safe depth, the effects of nitrogen narcosis disappear completely. Some evidence exists that certain divers may become partially acclimated to the effects of nitrogen...
There is no real "treatment" as such, but the symptoms usually alleviate rapidly by reducing your depth.AdditionThe above is correct, except that ascending to a shallower depth is in fact the...
A diagnosis must be made on circumstantial evidence of atypical behavior, taking into consideration the depth of the dive and the rate of compression. Nitrogen narcosis may be differentiated from...
It doesn't. Nitrogen narcosis is a nitrogen toxicity that happens only at depths of 100+ ft. Decompression Illness or "The Bends" is what happens when divers ascend too quickly.
