What is the recommended treatment for nitrogen narcosis?

The recommended treatment for nitrogen narcosis is to ascend until the feeling goes away. Nitrogen narcosis occurs when a diver is exposed to high partial pressures of nitrogen, leading to symptoms similar to intoxication, such as impaired judgment and decreased motor skills. The primary cause of these symptoms is the increased concentration of nitrogen in the body due to the depth at which the diver is operating.

Ascending to a shallower depth reduces the pressure on the body, which in turn decreases the partial pressure of nitrogen. This allows the nitrogen to be expelled from the body more effectively, leading to a rapid resolution of the narcotic effects. By moving to a shallower depth, divers can often relieve symptoms without further complications.

The other options, such as taking deep breaths or staying at depth, do not address the issue effectively, as remaining at depth could worsen the narcosis. Using supplemental oxygen is not a direct treatment for nitrogen narcosis and is primarily used to treat other diving-related issues, such as decompression sickness, rather than the effects of nitrogen itself.
