The UTD Nitrox specialty is designed to give the student the knowledge needed to safely dive and enjoy the many benefits backgas breathing mixtures with an oxygen content of 32% (EAN32) offer.
Breathing Nitrox allows for extended time and/or safety margins over air in depths to 100fsw/30m. However, like anything else, it does has its risks and considerations.
This single day course focuses on the practical and theoretical aspects of breathing high-oxygen gas mixtures, gas laws and physics, physiology, gas blending and safety, maximum operating depths (MOD), "Min Deco", standard gases and an academic introduction to decompression diving.
We'll then dry run dive team order and protocols, descent & ascent procedures, S-drills and touch contact and oxygen toxicity rescue procedures. Dry runs allow the student to practice the skills on land, before entering the water, under the watchful eye of the instructor(s)
We then put the new knowledge to practical use by planning and executing two dives using EAN32. The dives will focus on pre-dive procedures, buoyancy and trim, proper descents, proper ascents with deep stops, gas sharing scenarios to include horizontal touch contact swims and gas sharing ascents and rescue of a diver simulating oxygen toxicity.

Rentals are available for most equipment. If you have any questions on equipment requirements or rentals, please contact us prior to registering.
The class also addresses gas planning, creating an understanding of "Rock Bottom" or "Min Gas", in detail.
Who is this class designed for?
The UTD Nitrox mini is for any diver wanting to incorporate Nitrox into their diving, whether it be to add a margin of safety, extend their bottom times at recreational depths, prepare for technical dive training, or simply add to their knowledge of recreational decompression.
The end result is a diver who is able to properly plan, execute and enjoy dives using our standard gas of 32% Nitrox (EAN32).
Why take this class?
To expand your diving knowledge and abilities and take advantage of the benefits Nitrox offers.
Nitrox allows for extended bottom times and adds a margin of safety, since by raising the oxygen content, we lower the inert gas (nitrogen) content.
However, with any benefit comes a tradeoff. While increasing our oxygen content in our breathing gas brings advantages, it also has its risks and considerations, including oxygen toxicity.
This class provides the diver the knowledge to safely incorporate Nitrox into his/her diving, enjoying its many benefits as well as understanding its limitations.
The Nitrox mini is a single day class which includes academic discussions, dry runs and 2 dives.
Academic discussions include the history of Nitrox, uses and misconceptions about Nitrox, physics of gas laws and partial pressures, physiology, oxygen exposure and oxygen toxicity and gas planning and management, including Rock Bottom (min gas). We also discuss, in detail, decompression strategies, min-Deco dive planning, blending and mixing Nitrox breathing gases, analyzing gas mixtures and safe diving practices and procedures.
We'll finish up the academics with a discussion on dive planning using Nitrox (including using tables and/or dive computers), standard gas mixes, equivalent air depth, maximum operating depth (MOD), gas analysis and cylinder labeling.
