What is the primary benefit of diving with enriched air?

How does using enriched air well within air no decompression limits affect safety?

What is the primary benefit of using enriched air? It exposes you to less nitrogen, which cause DCS. … 2) Reduces need to “Push” air No Decompression Limits. 3) Reduces overall Nitrogen load on multiple dives.

What is the primary risk associated with diving Nitrox?

The primary risk associated with Nitrox diving (as opposed to diving air) is carbon monoxide (CO) poisoning. … Additional steps Nitrox divers can take to help avoid oxygen toxicity include all of the following except: Never exceed a PO2 of 2.0.

What is different about Nitrox diving?

Nitrox is a combination of gases, used in scuba diving, different from the air we commonly breathe. It’s composed of oxygen and nitrogen of 21% and 79% respectively. While Nitrox or enriched air, contains a higher proportion of oxygen than atmospheric air.

Is nitrox better than air?

Nitrox allows you to spend more time at depth compared to diving on air, which means you’ll get a lot more out of your diving holiday. Even if you’re only making one dive, but it’s deeper than 15 metres/50 feet, nitrox is beneficial.

How deep can I dive with 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.

What is the primary concern regarding enriched air nitrox and equipment?

The Primary concern regarding enriched air nitrox and equipment is the high oxygen content. You may use equipment, other than cylinders, with enriched air up to 40% oxygen, without modification.

How is PPO2 calculated?

To calculate a partial pressure we need to know two important things: 1) the percentage of the gas in the breathing mix and 2) the depth of the dive. Dalton’s Law is represented mathematically as PPO2=Fg x P (partial pressure of oxygen = fraction of oxygen x Pressure).

At what depth do you need to decompress?

The deeper and longer your dive the more chance you need decompression stops. Shallow dives of 6-10 metres (20-30 feet) you can spend over 200 minutes without a decompression stop. Dives to over 30 metres (100 feet) limit your dive time to around 20 minutes before a decompression stop is required.

Why is EAN32 a good choice for Nitrox diving?

The reason EAN32 is considered the optimum Nitrox mixture is because it is the most oxygen rich mixture that you can use up to the maximum recommended sport diving depth limit of 40 m/132 ft. … In addition, using EAN32 poses less risk in terms of exposure to oxygen than other richer mixtures.

At what depth does oxygen become toxic?

Oxygen toxicity occurs in most people when the partial pressure of oxygen reaches 1.4 atmospheres or greater, equivalent to slightly over 187 feet (57 meters) depth when breathing air (shallower depths when breathing oxygen concentrations greater than 20%).

Is nitrox safer than air?

Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen. … Nitrox is not a safer gas than compressed air in all respects; although its use can reduce the risk of decompression sickness, it increases the risk of oxygen toxicity and fire.

Do you feel better diving with Nitrox?

If you ask most people that dive on Nitrox, they will all say the same thing, they feel a lot better when diving on Nitrox than they do after diving on normal air.

When should I use Nitrox?

The best application of nitrox is in the 50- to 100-foot range. No stop times for dives shallower than 50 feet are often so long that you’ll empty your tank before you run out of dive time.
