- Nitrogen narcosis is NOT the bends. Nitrogen narcosis is also known as rapture
- of the deep. It occurs at depth. The bends are the result of nitrogen coming
- out of solution. It occurs when the pressure decreases, not at depth.

- No. Nitrogen narcosis (a.k.a. rapture of the deep) occurs at depth, not during
- ascent.

- What you say is true of the bends. Unfortunately, it has nothing whatever to
- do with nitrogen narcosis (other, of course, that you don't develop nitrogen
- narcosis if you don't breathe nitrogen).
