Nitrogen narcosis is a reversible alteration in consciousness that happens when a diver breathes compressed air at depths better than about 100 toes (30 meters). The consequences of nitrogen narcosis are just like these of alcohol intoxication, and might embody euphoria, disorientation, impaired judgment, and lack of coordination.
Nitrogen narcosis is attributable to the elevated partial strain of nitrogen within the diver’s physique at depth. Nitrogen is a comparatively inert gasoline, however at excessive partial pressures it might dissolve into the diver’s tissues and have an effect on the functioning of the central nervous system. The consequences of nitrogen narcosis may be exacerbated by chilly water temperatures, fatigue, and stress.
