What condition is characterized by a state of stupor due to nitrogen effects under high pressure?

Nitrogen narcosis is characterized by a state of stupor that occurs due to the effects of nitrogen under high pressure, particularly during deep dives. When a diver descends beyond a certain depth, the partial pressure of nitrogen increases, which can lead to a narcotic effect similar to alcohol intoxication. This condition impairs judgment, coordination, and response times as nitrogen affects the central nervous system.

In the context of diving, nitrogen narcosis often becomes significant at depths greater than about 30 meters (100 feet). Divers may experience symptoms such as euphoria, overconfidence, and in severe cases, a loss of consciousness or cognitive functions. Prompt recognition and ascent to shallower depths typically resolve the symptoms, making it crucial for divers to be aware of this risk.

Other conditions like hypercapnia, decompression sickness, and barotrauma relate to different physiological effects and problems divers may face, but they do not specifically describe the narcotic state induced by nitrogen at depth.
