How do you recognize a diver suffering from nitrogen narcosis?

• A. Shallow and rapid breathing
• B. Signs of impaired judgment and confusion
• C. Physical exhaustion without symptoms
• D. Excessive buoyancy control

Answer: (B)

Recognizing a diver suffering from nitrogen narcosis primarily involves observing signs of impaired judgment and confusion. Nitrogen narcosis, often referred to as "the rapture of the deep," affects the central nervous system as a diver descends deeper underwater, leading to a state that resembles intoxication. This condition can result in cognitive impairment, making divers unable to make sound decisions or process information correctly. Symptoms may include disorientation, poor judgment, exaggerated emotions, and a lack of awareness of one’s surroundings. For instance, a diver may exhibit behavior such as taking risks they normally wouldn’t or failing to follow safety protocols. This is critical in a diving context, as misjudgment can lead to dangerous situations, such as ignoring ascent rates or failing to monitor air supply. While shallow and rapid breathing, physical exhaustion, and excessive buoyancy control can occur for various reasons during a dive, they are not specific indicators of nitrogen narcosis. Therefore, recognizing the behavioral changes associated with impaired judgment and confusion is essential for identifying this condition during a dive.
