What is Nitrox made from?
Any gas mixture containing nitrogen and oxygen (except trace gases) is called Nitrox. This includes atmospheric air which contains approximately 78% nitrogen and 21% oxygen. Underwater diving is where nitrox is most commonly used. Nitrox can be distinguished from air and treated differently.
What are the benefits of Nitrox diving, you ask?
The Benefits of Diving with Nitrox
- Longer Bottom Times. Many people dive with Nitrox because it allows them to stay underwater for longer periods of time.
- Shorter Surface Intervals.
- Longer Repetitive Dive Times.
- Reduction in post-dive exhaustion
- The Oxygen Toxicity Limits and the Depth Limits
- Use of Special Gear
The next question is: How deep can you go with Nitrox? The danger of oxygen toxicity is well within recreational diving's depth limits. Nitrox can be used to dive at a depth of 121 feet for 32 percent and 36 percent respectively. Divers regularly cruise to these depths or deeper, and many don't even think twice about it.
Similar to the previous question, what's the difference between Nitrox or Air?
Air is essentially 21% oxygen and 79% nitrogen. ANitroxa is any mixture of nitrogen or oxygen. Aenriched aira is a mixture of nitrogen and oxygen that contains more than 21% oxygen.
When is Nitrox best used?
This is the best area to use Nitrox. The decompression times for diving below 50 feet are so long that recreational divers often empty their tanks before they run out.

How deep can a human dive?
130 feet
At what depth does oxygen become toxic?
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.
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 divers use pure oxygen?
Pure Oxygen Is Used in Technical Diving
Pure and high percentage mixes of oxygen (such as nitrox or trimix) are used by trained technical and recreational divers to extend bottom times and to speed decompression. On the surface, pure oxygen is recommended first aid for the majority of diving injuries.Is scuba diving dangerous at 30 feet?
The 30-foot-per-minute rate may not always be practical for the whole ascent, especially when you are deep and low on air or approaching hypothermia. In that case a faster rate, up to 60 feet per minute, is acceptable, but for the final 60 feet of your ascent, you should slow to 30 feet per minute.
Can you scuba dive to see the Titanic?
The Dive. You will journey to the wreck of the Titanic aboard the MIR I or II submersibles. They are capable of reaching ocean depths of 20,000 feet (6,000m). This means they can reach 98% of the ocean floor worldwide.
Why do divers use nitrogen?
Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis and may improve ease of breathing. During filling there is a risk of fire due to use of oxygen and a risk of explosion due to the use of high-pressure gases.
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.
Should I get Nitrox certified?
Longer Repetitive Dive Times
Nitrox becomes especially beneficial for divers who are doing more than one dive per a day. A diver using nitrox will have a longer allowable bottom time on a repetitive dive than a diver using air because the diver using nitrox has absorbed less nitrogen.Does air go bad in scuba tanks?
Technically, properly filtered air in a good clean tank should never go bad. There are plenty of reports of people doing dives on tanks that have sitting around for 10+ years and did just fine. OTOH, there are also a few reports of people who died as a result of bad gas or insufficient o2 in old tanks.
Can Nitrox tanks be filled with air?
Nitrox divers often have their cylinders refilled with air for dives in which having Nitrox may not offer any appreciable benefit. If you do so, and if your cylinder is O2 service rated, you must use only oxygen compatible air.
How much does nitrox certification cost?
The cost is $179.00. Price includes either the PADI E Learning Access Pass or text book, a demonstration on acquiring and logging Nitrox tanks and fills, the PADI Enriched Air Certification Card upon completion. There are no open water dives required or included in this class.
How deep can you dive on air?
130 feet
How do you calculate Nitrox mix?
Calculations in feet
The equivalent air depth can be calculated for depths in feet as follows: EAD = (Depth + 33) × Fraction of N2 / 0.79 − 33. Working the earlier example, for a nitrox mix containing 64% nitrogen (EAN36) being used at 90 feet, the EAD is: EAD = (90 + 33) × 0.64 / 0.79 − 33.Why is helium mixed with oxygen for divers?
The main reason for adding helium to the breathing mix is to reduce the proportions of nitrogen and oxygen below those of air, to allow the gas mix to be breathed safely on deep dives. Helium has very little narcotic effect. A lower proportion of oxygen reduces the risk of oxygen toxicity on deep dives.
What is the maximum recommended depth for using 100 percent oxygen?
The maximum recommended depth for using 100 percent oxygen is 6 m/20 ft. 29. 12. The term EAN32 refers to a Nitrox mixture in which the Fraction of Oxygen is 32 percent.
