What is a common symptom of nitrogen narcosis?

Impaired judgment is a common symptom of nitrogen narcosis, which is a condition affecting divers who experience increased levels of nitrogen in their bloodstream as they descend to depths greater than approximately 30 meters (100 feet). This condition occurs because nitrogen acts as an anesthetic when under pressure, leading to effects similar to those of alcohol intoxication. Divers may exhibit poor decision-making skills, lack of coordination, and reduced ability to assess risk appropriately.

In the context of deep diving, the impairments can lead to dangerous situations, as divers might misinterpret their surroundings or fail to recognize the need to ascend. Therefore, awareness of this symptom is crucial for the safety and effectiveness of diving operations. Understanding nitrogen narcosis and its impacts helps divers maintain clear judgment and avoid potential mishaps during their dives, reinforcing the importance of safety protocols and training in underwater environments.
