Narcosis while diving (also known as nitrogen narcosis, inert gas narcosis, raptures of the deep, Martini effect) is a reversible alteration in consciousness that occurs while diving at depth. It is caused by the anesthetic effect of certain gases at high pressure.

How can you prevent narcosis?

At what depth does nitrogen narcosis occur?

Nitrogen narcosis describes the anesthetic effect of increased nitrogen levels that typically occurs in divers at depths below 70 feet of sea water (fsw). Symptoms include light‐headedness, euphoria, and loss of fine motor coordination.
