Scuba equipment - The Nature and Benefits of Nitrox Mixtures

We all know that compressed Air stored in the diving cylinder consist of of atmospheric gases that hold a maximum pressure rating of 3000 to 4500 psi. When we say atmospheric gases, we refer to a blend of Oxygen, Nitrogen and other inert gases that make up the earth's atmosphere. In terms of proportion, Nitrogen accounts for colse to 78% of air followed by Oxygen at 21% and the remaining 1% consist of of inert gases such as Argon and Carbon Dioxide.

Non-divers are perhaps predisposed to the opinion that the same proportion occurring in breathing gases is ideal for use in the escort of scuba diving activities. While most recreational divers are geared up with an open circuit scuba set designed to be 'Air' compatible (out of the box), many seasoned scuba divers would prefer the use of Enriched Air Nitrox (Eanx). Nitrox gases consist of higher proportions of Oxygen at a maximum rate of 40% and lowered proportions for Nitrogen. For example, a blend of Ean32 implies a blend of 32% oxygen and 68% nitrogen. Wonder why Nitrox mixtures are regarded as better distinguished to scuba diving than the quarterly Air mix? Well here's how.

3000 Psi

The lowered Nitrogen content in Nitrox or Eanx mixtures decelerates the absorption of Nitrogen into the blood and corporeal tissues to effectively enlarge No Decompression Limits (Ndl) or No Stop Times and growth bottom times than what the quarterly breathing gas blend would allow. Consequently, use of Nitrox gases in the escort of repetitive dives will help sacrifice Residual Nitrogen Time (or the duration of excess Nitrogen extraction from the body) and likewise allow for shorter surface intervals in the middle of 2 consecutive dives. Now you wouldn't feel these benefits in the use of atmospheric Air mixtures. Nonetheless, these advantages are not available without cost considerations. Whereas Air can be de facto derived from the atmosphere and ready (apart from being virtually free), Nitrox mixtures are commonly expensive. Using Nitrox gases during your dive would cost you colse to per tank and would likewise require the diver to endure formal training to get Nitrox certified.

Neophyte divers would initially dispense with the idea of using Nitrox mixtures. But as the scuba diver advances with training and skill; with a whole of certifications and open dives in his dive logbook, the intent of using more specialized scuba tool also arises. Therefore, it would be wise to spend on Nitrox-compatible scuba tool early on from the scuba regulator, octopus regulator and dive computer. The Aeris A1 scuba regulator is Nitrox-compatible and can handle gas mixtures of up to 40% Oxygen without requiring extra preparations or maintenance. To improve your margin of safety, get a matching A1 Octopus regulator that has been configured for Nitrox use as well. Meanwhile, the Aeris Xr-2 Wrist Dive Computer [http://www.scubasuppliers.com/site/1408308/product/10.2610] can be programmed to function as an Air computer and then as a Nitrox computer for mixtures of 21% to 50%.
