What are the signs and symptoms of nitrogen narcosis?

Nitrogen narcosis, sometimes referred to as "the rapture of the deep," is a condition that divers may experience when they descend to depths typically greater than 30 meters (100 feet). It results from the inhalation of nitrogen at higher partial pressures, which can lead to a range of neurological effects.

The signs and symptoms associated with nitrogen narcosis prominently include euphoria, which can create a false sense of well-being and confidence. Divers may also experience slowed response times, making it difficult to react quickly to underwater situations. Additionally, memory loss can occur, where divers may struggle to remember tasks or safety protocols, significantly impacting their ability to dive safely.

Understanding these symptoms is crucial for divers as they can lead to impaired judgment and decision-making underwater, potentially resulting in dangerous situations. Recognizing and responding to these symptoms can help divers avert the risks associated with nitrogen narcosis.
