Why do divers use nitrox?

Enriched Air Nitrox, nitrox with an oxygen content above 21%, is mainly used in scuba diving to reduce the proportion of nitrogen in the breathing gas mixture. The main benefit is reduced decompression risk.

What are the advantages of Nitrox diving?

Diving with nitrox means your body absorbs less nitrogen on a dive than someone who is diving with a standard air tank with 21% O2. You’ll have less nitrogen to off-gas during your surface interval so you can get back into the water sooner than someone who is not diving with nitrox.

Is Nitrox better than air?

Breathing air which is enriched with more oxygen reduces the amount of nitrogen and therefore reduces the risk. A dive on Nitrox will be much safer than the same dive profile on air. … Nitrox divers are able to extend their NDL because the gas that they are breathing has less nitrogen than a diver’s on air.

How deep can you dive with 32 Nitrox?

However, when diving on nitrox, the potential for oxygen toxicity lurks well within the depth range of recreational diving: the maximum depth on 32 percent nitrox is 121 feet; on 36 percent nitrox, it’s just over 100 feet. Many divers regularly cruise at these depths and even deeper without giving it a second thought.

How does nitrox diving work?

How does nitrox work? As we’ve all learned from certification, when you dive, the water pressure causes nitrogen from the air you’re breathing to dissolve in your bloodstream. The higher the pressure, the more nitrogen will dissolve.

Is it worth getting Nitrox certified?

So if you’re thinking of doing the Nitrox course then our advice is, do it – it is well worth it. You learn alot, increase your diving knowledge and it will no doubt come in very handy on many of your dives.

How long does it take to get Nitrox certified?

The PADI Enriched Air Diver Course online will take approximately 3 hours to complete.

Do you need a special regulator for Nitrox?

It is not essential to buy a special regulator if you only plan to dive with mixtures containing 40 percent oxygen or less. But the real difference is more than skin deep, and Nitrox regulators have special o-rings, Nitrox compatible seats, and use special lubricants. …

Does nitrox reduce narcosis?

Nitrox reduces the risk of inert gas narcosis.

In some cases, divers have more problems with narcosis when using enriched air. Always stay vigilant for signs of narcosis when making any deep dive.

How much does nitrox certification cost?

Q: How much does nitrox training cost? A: The cost for proper training is around $150.00 for basic nitrox. Q: What are the prerequisites to take a nitrox course? A: You must be 15 years of age or older and should be comfortable with your equipment and diving conditions in your area.

At what depth do you need to decompress?

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.

At what depth does air become toxic?

The higher the Fio2 the greater the risk. Breathing air containing 21% oxygen risks acute oxygen toxicity at depths greater than 66 m; breathing 100% oxygen there is a risk of convulsion at only 6 m.

Why Scuba diving is dangerous?

Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.

How long does a Nitrox tank last?

Take that same mix to 60 feet, where the normal bottom time is 50 minutes, and your no-decompression limit extends to 130 minutes. The problem there being that unless you have a massive tank or an absurd SAC rate- you can’t stay at 60 feet for 130 minutes.

How deep can a certified diver dive?

The industry standard depth limit for recreational divers is 130 feet (39 m) at sea level. During the basic scuba certification, students experience depths of 30-60 feet (9-18 m), and a “deep” dive is considered more than 60 feet (18 m).

How long can you dive at 60 feet?

A not uncommon 2 tank dive trip might be the first dive at a max of 90 feet with a max time underwater of 35 minutes while the second dive might have a profile of max depth of 60 feet with a max time underwater of 50 minutes.
