Also known as Enriched Air Nitrox (EANx), it is a diving gas containing a higher percentage of oxygen than regular air.

As a result, you can stay underwater for longer. <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>More oxygen means less nitrogen in breathing gas<\/li>\n\n\n\n<li>Nitrogen in breathing gas causes DCS<\/li>\n\n\n\n<li>Nitrox decreases nitrogen absorption, enabling longer bottom time on dives<\/li>\n<\/ul>\n\n\n\n<p>This is often the only benefit of nitrox taught in most recreational diving courses. Simply raising the percentage of oxygen lowers the amount of nitrogen in our breathing gas. Because we breathe in less nitrogen, it saturates our tissues less rapidly<\/p>\n\n\n\n<p>On recreational scuba dives, nitrogen content in the breathing gas is what causes <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/types-decompression-sickness-dcs\/\">decompression sickness<\/a> (<a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/types-decompression-sickness-dcs\/\">DCS<\/a>) in divers. In contrast, oxygen is metabolized inside the body and, therefore, cannot create damaging bubbles.<\/p>\n\n\n\n<p>Decreasing the amount of nitrogen in the breathing gas enables significantly longer bottom time on a dive. Alternatively, it permits less nitrogen absorption over a given dive profile compared to using regular air.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"1080\" height=\"607\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/03\/Andy-Davis-Sidemount-Diving-141-1-edited.jpg\" alt=\"Benefits of nitrox when scuba diving. 1.

Breathing a higher fraction of oxygen speeds up nitrogen leaving your body.<\/p>\n\n\n\n<p>In short, one of the safety benefits of nitrox is that it accelerates the removal of nitrogen.

As a result, it enables longer bottom times on dives. It also increases nitrogen removal on the ascent and limits microbubble formation.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673042209\"><strong class=\"schema-faq-question\">What is the 40% rule in Nitrox diving?<\/strong> <p class=\"schema-faq-answer\">In recreational diving, the O2 fraction in nitrox is limited to 40%. As a result, scuba cylinders and regulators do not need to be O2 clean and compatible. This prevents the risk of fire and explosion.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673068916\"><strong class=\"schema-faq-question\">Should I dive Nitrox or air?<\/strong> <p class=\"schema-faq-answer\">Whilst it is cheaper to dive with air, nitrox has 3 significant benefits for scuba diver safety and enjoyment. It increases diving bottom time and removes more inert gas on the ascent. This lowers DCS risk and helps prevent microbubbles from causing post-dive fatigue.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673089713\"><strong class=\"schema-faq-question\">What are the risks of Nitrox diving?<\/strong> <p class=\"schema-faq-answer\">Nitrox has a depth limit. Beyond that limit, the <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/scuba-gas-laws-for-diving-physics\/\">partial pressure<\/a> of oxygen is too high. In turn, that can cause seizures and the diver can drown. Nitrox divers are trained to calculate the maximum safe depth for a nitrox mix.<br \/><\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673111898\"><strong class=\"schema-faq-question\">How does nitrox affect narcosis while diving?<\/strong> <p class=\"schema-faq-answer\">The diving community has debated for many years whether O2 has a narcotic effect on divers. Recent science seems to indicate that oxygen can contribute to narcosis.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673134833\"><strong class=\"schema-faq-question\">What happens if you dive too deep with nitrox?<\/strong> <p class=\"schema-faq-answer\">If a diver exceeds the maximum operating depth (MOD) for a nitrox mix they risk <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/oxygen-toxicity-thalmann\/\">oxygen toxicity<\/a>. This can cause convulsions or seizures, which often lead to drowning.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673158666\"><strong class=\"schema-faq-question\">Can you dive deeper with nitrox?<\/strong> <p class=\"schema-faq-answer\">No. Nitrox has shallower maximum operating depths than air. Nitrox has a higher O2%, which means a greater risk of oxygen toxicity seizures.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673185405\"><strong class=\"schema-faq-question\">Is nitrox safer for scuba diving?<\/strong> <p class=\"schema-faq-answer\">Nitrox has safety advantages and disadvantages. It improves diver safety by reducing the risk of DCS and decompression stress. On the other hand, it introduces the risk of oxygen toxicity.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1682673212680\"><strong class=\"schema-faq-question\">Why is it called nitrox?<\/strong> <p class=\"schema-faq-answer\">Nitrox is a contraction of the words\u00a0<strong>Nit<\/strong>rogen and\u00a0<strong>Ox<\/strong>ygen.
