Dangers of nitrogen - Les dangers de l'azote

- Nitrogen is a divers nemesis. At depth, under the pressure of the water around him, it builds up in his tissues. Like a slow anesthesia, the gas can render the diver drunk from nitrogen narcosis. More seriously, if a diver resurfaces too quickly, the nitrogen can form bubbles that lodge in joints, organs or blood vessels, causing permanent injury and even death. The solution: a recompression chamber where the diver can be returned slowly to sea-level pressure as his lungs exhale the excess gas.

- L'azote est un fléau pour le plongeur. En profondeur, sous la pression qui s'exerce sur lui, l'azote s'accumule dans ses tissus. Le plongeur peut ressentir une sorte d'ivresse due à l'excès d'azote appelée narcose à l'azote ou ivresse des profondeurs, qui agit comme une lente anesthésie. Mais il y a plus grave : si un plongeur refait surface trop rapidement, l'azote peut former des bulles qui se logent dans les articulations, les organes ou les vaisseaux sanguins, ce qui peut entraîner une invalidité permanente, voire la mort. La solution : un caisson de décompression où le plongeur est doucement ramené à la pression atmosphérique au niveau de la mer pour que l'excès d'azote présent dans son sang puisse être éliminé à un rythme tolérable par l'organisme.

@a10fjet And maybe DCS

LOL at the dog at the end

So you could build a chamber and go in it and pressurize it and get drunk?

@Den9082 I am sorry to say you are wrong... the dive doctor at edge water hospital also could not believe that i could have the bends but after checking my reflexes he was convinced. it was a 90 foot dive in cold lake superior @ 2 minutes i found a dive belt and returned with a short decompression stop for practice.the doc thinks the 32 degree water slowed my release of nitrogen. both my knees locked up 1 1/2 hr later. 3 hrs on pure oxygen= $3000.00. no more deep or repetive dives for me

@1234567jelly said, "the bends hit me 1 1/2 hours after a short clean dive where i was way under time and practiced some decompression stops for practice"... I think this is not true. The bends do not hit you just all of a sudden and out of the blue if your were "way under time" on a "clean dive". It's simply impossible or you have some other health problems of pulmonological (lungs) or cardiological(heart) nature...

@boolykbol nitrogen narcosis can hit you in much shallower water. they usually mention that 100 feet and beyond hits the hardest but some divers get it before 100 !

@prg4533 buying a computer will not make you "safer" . i have been diving for 31 years without a computer. one regulator rig has a depth and air gauge and the has only a depth gauge. i know how to caculate my tank time at differant depths . the only battery operated gear i own are the lights for cave and night diving. i would never want to rely on a battery operater computer . what do you do when your computer poops out under water?

@elykat the bends do not always hit quickly after a dive. i spent 3 hours locked in the recompression chamber that was the size of a mini sub it sucked and cost me $3000.00 cash 20 years ago. the bends hit me 1 1/2 hours after a short clean dive where i was way under time and practiced some decompression stops for practice.
