Nitrogen Narcosis Sedation and Consciousness<\/h1>\n\n\n\n

If you are a scuba diver, you may think you understand nitrogen narcosis. Sadly, what is taught in most scuba diving courses is mostly fiction. In this article, I will explain the reality of nitrogen narcosis sedation. To stay safe on your deeper dives, you need to know how the anesthetic effects of nitrogen progressively reduce your level of consciousness.<\/p>\n\n\n\n

The commonly taught model of alcohol-like intoxication utterly fails to describe the profoundly nuanced cognitive effect upon the diver and, at worst, promotes divers towards a dangerous misbelief that they aren’t mentally impeded by narcosis on their deeper dives.<\/p>\n\n\n\n

The sedative effect of nitrogen narcosis degrades communication between different parts of the brain; especially in regard to accessing the different memory systems that enable higher levels of consciousness and cognition (anterograde amnesia)<\/b>.<\/p>\n\n\n\n

Narcosis is essentially a slow progression through sedative effects towards unconsciousness as you go deeper (and the narcotic dose gets higher<\/em>).<\/p>\n\n\n\n
