31. The Navy, which must keep its divers free of nitrogen narcosis and the bends, is obviously interested. 32. A hangover, combined with the reduced physical capacity that goes with it, makes nitrogen narcosis more likely. 33. Tests have shown that all divers are affected by nitrogen narcosis , though some experience lesser effects than others. 34. A common misconception is that nitrox can reduce narcosis , but research has shown that oxygen is also narcotic. 35. However, Frunze was administered a chloroform dose that many times exceeded the dose normally applied to induce narcosis . 36. In contrast, narcosis II symptoms include stimulation of respiratory-cardiovascular responses followed by generalized depression of activity. 37. Helmet divers are subject to the same pressure limitations as other divers, such as decompression sickness and nitrogen narcosis . 38. Narcosis is a reversible state that is considered nonspecific because a single mechanism of action has yet to be established.39. Significant impairment due to narcosis is an increasing risk below depths of about, corresponding to an ambient pressure of about. 40. Many divers find that the level of narcosis caused by a dive, whilst breathing air, is a comfortable maximum.
