- The pp of NO2 would be the same in a chamber at an equivelent depth of
- FSW and the actual FSW but 1. It is thought that CO2 is a factor in
- narcosis and you could well be building up more CO2 while swimming
- around than sitting still and 2. Depending on you you might notice
- narcosis while in a hostile environment where having your head together
- means survival vs while in a chamber where it's out of your hands,
- anyway.
