Nitrogen Narcosis is the result of increased Partial Pressure of Nitrogen as we dive deeper down the water column. Narcosis is generally believed to start around 100fsw when diving on air and the effects increase as we dive deeper. Many factors contribute to Nitrogen Narcosis and it has been described as Euphoric or Acting Care Free. You can experience Narcosis in the safety of our Hyperbaric Chamber and get an idea of what it feels like so that you are prepared if it should appear during your dive.

Narcosis Nights begins with a short classroom presentation on Narcosis, followed by a Chamber Safety Briefing. After the briefing you will take a quick tour of the chamber then enter and prepare for your dive. You will descend at approximately 20fpm in the chamber allowing you time to clear your ears. As you approach 100fsw you will start playing cognitive games to test your mental acuity. The dive will continue to 130fsw with a short stop to ensure everyone is good to continue.We can dive you to a depth of 165fsw before returning to surface.  

Narcosis Nights is open to any level of certification. It does get warm in the chamber so you may want to bring a change of clothes for after your dive. You will be in the chamber with Trilogy Dive Center Staff members that will provide safety oversight during your dive and lead you through your cognitive activities. 

This is a great opportunity to learn about hyperbaric chambers, take a ride, and get narked!
