What effect does nitrogen absorption have on divers?

Nitrogen absorption is an important factor for divers to understand, particularly because it can lead to a phenomenon known as inert gas narcosis. This condition occurs when nitrogen, which is the primary gas divers breathe, dissolves into their bloodstream under pressure and starts to have a narcotic effect on the central nervous system. As a diver descends, the increased partial pressure of nitrogen leads to a rising concentration of nitrogen in the body, which can impair cognitive functions and coordination, much like alcohol intoxication. The signs can include confusion, poor judgment, and impaired motor skills, all of which are critical considerations for diver safety.

The statement that nitrogen absorption can affect intoxication levels highlights the potential dangers of deep diving, especially in environments where divers may not be able to monitor their mental or physical performance effectively. Understanding this effect is crucial for divers to make informed decisions about their depth and bottom time during dives.
