How can a diver recognize symptoms of nitrogen narcosis?

Recognizing symptoms of nitrogen narcosis is essential for divers to ensure their safety while underwater. Nitrogen narcosis occurs when nitrogen, which is inert at surface pressure, begins to exhibit anesthetic properties at increased depths due to the partial pressure of nitrogen increasing. The most distinct symptoms include feelings of euphoria, confusion, and impaired judgement, which can lead to critical decision-making errors underwater. This state can impair a diver’s ability to assess their environment, make safe diving decisions, and respond appropriately to emergencies.

Other choices relate to important aspects of diving safety but do not directly relate to the specific symptoms of nitrogen narcosis. Monitoring breathing patterns may indicate other physiological issues, changes in body temperature could suggest hypothermia or other conditions, and checking equipment functionality is crucial for safe diving practices but does not address the neurological effects of nitrogen narcosis. Understanding the psychological and cognitive effects is key for divers to recognize and respond to nitrogen narcosis effectively.
