What is the advantage of nitrox diving?
The Nitrox we use in recreational scuba diving is between 21 and 40% oxygen, and contains a lower percentage of nitrogen than air. This reduced percentage of nitrogen in recreational Nitrox allows divers to extend their no decompression limits or dive time by reducing the amount of nitrogen absorbed.
Should I dive with nitrox?
Divers who use nitrox absorb less nitrogen, making them stay underwater for longer. They’re also less likely to get decompression sickness. It’s worth noting that older divers and those who’ve experienced decompression sickness or physical injuries can reduce no-decompression limits with the gas.
Why must divers using nitrox adhere to special dive tables?
Simply put, nitrox – air with additional oxygen content – allows divers to enjoy longer bottom times (and shorter surface intervals) than their air-breathing dive buddies, while staying within the limits that were stressed in their open water training.
Why do you dive with nitrogen?
Divers breathe a mixture of oxygen, helium and nitrogen for deep dives to avoid the effects of narcosis. … Narcosis while diving (also known as nitrogen narcosis, inert gas narcosis, raptures of the deep, Martini effect) is a reversible alteration in consciousness that occurs while diving at depth.
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. Many divers regularly cruise at these depths and even deeper without giving it a second thought.
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.
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 do divers use heliox?
It is used by technical divers to reduce narcosis when diving at deeper depths. With normal air (21% oxygen/ 79% Nitrogen) nitrogen narcosis becomes an issue at these depths. To reduces the effects of the narcosis we replace some of nitrogen found in air with some helium.
Does nitrox reduce narcosis?
Nitrox reduces the risk of inert gas narcosis.
Oxygen is just as narcotic as nitrogen under pressure. … 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.
