Nitrox is just oxygen enriched air.
If you used pure oxygen, it would be toxic past a depth of 20 feet / 6 meters.
There are various mixes of gases which can be used in diving tanks. The most commonly used one for recreational diving is normal air which consists of 80% nitrogen and 20% oxygen (and a small amount of carbon dioxide, argon and other gases) Sometimes the proportion of nitrogen - oxygen is change as follows: Air (80% nitrogen and 20% oxygen) Nitrox-28 (72% nitrogen and 28% oxygen) Nitrox-30 (70% nitrogen and 30% oxygen) Nitrox-32 (68% nitrogen and 32% oxygen) Nitrox-34 (66% nitrogen and 34% oxygen) These are just examples but different mixes can be made You can also use mixes of nitrogen, oxygen and helium. this mix is called trimix. Hope that helps
Yes, scuba cylinders can be cleaned and they are if they are going to be used with oxygen enriched air (i.e. nitrox). There is a debate whether they need to be cleaned if used for "low" oxygen nitrox if the nitrox is premixed.
The gas that you can use is filtered air or nitrox, which is nitrogen enriched air. There is CO2 used for some BC vests also for an emergency, you can detonate the CO2 to get up to the surface.
The gas commonly mixed with oxygen for diving is nitrogen. This mixture is called Nitrox or Enriched Air Nitrox, and it helps reduce the risk of decompression sickness when diving at certain depths.
Yes, nitrox is an oxidizer. It contains a higher percentage of oxygen than normal air, which can increase the risk of oxygen toxicity if not used properly. Nitrox is commonly used in scuba diving to extend bottom time and reduce the risk of decompression sickness.
By breathing nitrox (gases where the %O2 is higher as compared to air) or mixed gases (e.g. adding in helium) so that the partial pressure of nitrogen is reduced.
Nitrox is a gas that can boost your car speed by at about 17%. The highest speed percentage it can take your car to is about 39%.
Most scuba tanks are filled with compressed air (same as the "normal" air we breath) 21% Oxygen and 79% Nitrogen. The tanks are a variety of colors and the color does not signify anything. Special NITROX tanks have a bold Yellow and Green band which goes around the tank and is usually 8" wide. NITROX can have a range of between 32% and 50% oxygen (the balance is nitrogen). This yellow/green band - with the word NITROX can be placed on any color tank. Special tanks with exotic gas mixes will be indicated with special bands - there is no standard colors for exotic mixes.
Any inert gas will build up. In other words, any gas other than oxygen. So when diving on air or a nitrogen oxygen combination such as nitrox, then it will be nitrogen. But if you are breathing another type of mixture such as trimix (which also contains helium) then helium will also build up in addition to the nitrogen.
You can use any 1st and 2nd stage combo with nitrox up to %40.Additional commentThe contributor is correct that the scuba industry as a whole considers no modification is needed to a regulator if the nitrox is not greater than 40%. There are some pros and cons to this. However, a titanium regulator is NOT considered nitrox compatible by many. So be careful with that.
The dive computer essentially calculates in real time the nitrogen levels in your blood used on depth and time (and possible air mixture: ie: NITROX 32%) - they can (and do) much more than that including, timing your dive, ascent rates - some even calculate time left based on how much gas is left in your tank!!!
nitrogen is used in fertilizers
