   Positive

Positive Benefits of using Nitrox as a breathing gas

The primary concept of changing the amount of oxygen in your breathing is based on the type of diving you are planning to do.... The major benefits of using increased level of oxygen are:

  • Less Nitrogen in the mix means less decompression requirement.
  • Higher oxygen content on shallower dives means less risk of Decompression injury and longer bottom times.
  • Correct use of custom mixes will allow logner dive times and shorter deco stops...

   Negative

The Negative Effects of breathing Nitrox gas mixes.

The major problem for sports diving, is that a greater degree of discipline is required for safer diving with Nitrox. The Increased PPO2 of Oxygen can be fatal on deeper dives... If limits are observered and safety margins used, the risks are easily controlled and reduced.

Planning and execution of Dives on Nitrox MUST be with due care!

Generally the benefits out-weigh the negativess...

  Deep Diving

Nitrox gas and deeper diving...

As you should note from the column above "Nitrox" is NOT designed for deeper diving, if you want safer deep diving take a Trimix course... Trimix diving reduces the Nitrogen by adding Helium Gas to the breathing mix... Therefore Trimix (3x Gases, Oxygen, Nitrogen and Helium)...

NITROX IS NOT A DEEP GAS!

Ntech Nitrox "Technical Nitrox"

 

The difference between Nitrox and Technical Nitrox is that Nitrox for Sports diving is generally ONLY used in non-decompression diving and the whole dive is completed on one gas mix... Usually a 32% or 36% Nitrox Mix, upto 40% Maximum...  and Maximum depths 30m to 36m.

 About Technical Nitrox 

Technical Nitrox is about using Nitrox in "Decompression Diving" as both a travel gas and a Decompression Gas...

Ntech Technical Nitrox Diver (Ntech Diver)

We have  from September 2011 New Standards for our Ntech Nitrox "Tech" Diver Certifications

Level 1.

 

From Any Agency "Sports Nitrox Level" this can be your entry into technical diving, i.e. full decompression diving using nitrox as a decompression mix diving to 40m/132ft. on Air and making at least three stops to 9m/30ft. Then decompression on a 50/50% ~Nitrox Mix (For which you will require "Oxygen" clean equipment)....

Using "Oxygen or O2" clean equipment means that the same equipment cannot be used for normal scuba diving with air, and if it is used with an air mix there is the possibility of "Comtamination" and the equipment will need to Oxygen cleaned again...

 

  Ntech Nitrox Course Program

From September 2011 New Standards

This represents a major standards change from our older program, including more dives and more theory...

Our core Ntech Diver programs now consists of the following:

  • Theory: About Nitrox Diving - Understand Partial Pressure Physics - Changes in Physiology - Breathing Mixes, Benefits and Hazards of Nitrox Diving - CPR & First Aid for Nitrox - Equipment for Nitrox - Gas Mixes & Compressors - Dive Planning & Risks Assessment - Rescue with Nitrox - Limitations of training levels and Safety.
  •  Practical Training: 6 Open Water Dives - Dive 1, Assessment dive on 36% to planned limit.  (Effects of Breathing Nitrox). Dives 2, and 3. Decompression Diving using air from 30m/100ft to 40m/132ft.  Planning multiple stops. Dives 4, 5 & 6 using a gas switch at 9m/30ft. to a 50/50% Decompression Mix. Plus a recue skills assessment on dive 4 and make up assessment on rescue skills (If required on dives 5 and 6.)
  • Dive Training on Nitrox dives maybe combined with another specialist Program... i.e. Wreck Diving or Navigation etc. etc.

 

Level 2. Is our Advanced Ntech Nitrox Diver

Misunderstandings - Myths

 

Some people in the Sports diving world are still of the opinion that nitrox is a "Black Gas" and that it is somehow dangerous... The Military, NOAA, Research Agenices All over the world and Technical Diver have been using nitrox for three decades (30 Years)....

Nitrox has both positive and negative effects see panel on right, it really boils down to what type of diving you are interested in and do you want to maximise your safety in diving to avoid injuries?

If you are even just a resort sports with ITDA or an Open Water diver (Any Agency) then Nitrox is for you!

Ask your Instructor about diving Nitrox and getting trained and certified with your agency...
