What is nitrox and how is it different from air?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Recreational diving <strong>enriched nitrox air<\/strong> is any mixture of nitrogen\/oxygen gases with additional oxygen. The air you breathe when scuba diving is approximately <strong>21% oxygen<\/strong> and <strong>79% nitrogen<\/strong>In contrast, a nitrox mixture will have a higher proportion of oxygen \u2013 for recreational diving, this is usually <strong>32%<\/strong> or <strong>36%<\/strong>That&#039;s why you&#039;ll often hear these mixtures referred to as <strong>&quot;Nitrox 32&quot;<\/strong> or <strong>&quot;Nitrox 36&quot;<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You may also encounter the terms <strong>EANx36<\/strong> or <strong>EAN36<\/strong> \u2013 this means a gas mixture consisting of 36% oxygen and 64% nitrogen.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Ka_nirsana_ar_nitrox_atskiras_no_nirsanas_ar_gaisu\"><\/span>2. How is diving with nitrox different from diving with air?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The goal of EANx is not supplemental oxygen, but <strong>less nitrogen<\/strong>By reducing the amount of nitrogen you inhale, you can extend your bottom time without increasing the theoretical risk of decompression sickness (DCS).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The deeper (higher pressure) and longer you dive, the more nitrogen dissolves in your tissues.<\/strong> If you surface with too much dissolved nitrogen, bubbles can form, causing DCS. Staying within the no-decompression limits limits the theoretical amount of dissolved nitrogen so that you can ascend directly to the surface (making a safety stop) with a low risk of DCS.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example in deep diving:<\/strong> Imagine you are diving to a depth of 30 meters. On regular air, according to the Recreational Dive Planner (RDP), your no-decompression limit (NDL) is 20 minutes. But when diving with EANx32, your NDL at the same depth is 30 minutes.<\/li>\n\n\n\n<li><strong>Equivalent Air Depth (EAD):<\/strong> When using nitrox with air tables, you calculate an EAD, which tells you how much nitrogen you are taking in. For example, when diving 21 meters deep with EANx36, your EAD is 15 meters because you are taking in nitrogen as if you were 6 meters shallower with air.<\/li>\n\n\n\n<li><strong>Computer use:<\/strong> Nowadays, dive computers are most commonly used that calculate the benefits. In most cases, with EANx, dives, even repetitive ones, are limited by your gas supply, not your no-decompression time.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Nitrox_nirsanas_sertifikacija\"><\/span>3.

Myths about nitrox<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Nitrox is sometimes considered a panacea, but there are some myths:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Myth 1: Nitrox reduces nitrogen narcosis.<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Reality:<\/strong> At the depth (30-40 meters) where the risk of narcosis begins, you should stop using nitrox because of oxygen toxicity. Moreover, oxygen is just as narcotic as nitrogen. Dr. Peter Bennett writes that the preventive value of nitrox is \u201cvery small, so marginal that, in my opinion, it should be discounted.\u201d<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Myth 2: Nitrox reduces gas consumption.<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Reality:<\/strong> It doesn&#039;t work that way because most of the oxygen you inhale is exhaled unused. The next breath is determined by the need to exhale carbon dioxide, and is not affected by the contents of the tank.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Myth 3: Nitrox reduces fatigue.<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Reality:<\/strong> While many nitrox divers swear this is true, a blinded study of labeled and unlabeled cylinders found no difference. Bennett calls this the \u201cplacebo effect.\u201d<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Myth 4: You can dive deeper with nitrox.<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Reality:<\/strong> On the contrary, EANx sets a shallower depth limit. However, the myth may stem from the fact that technical divers use EANx, but not during the deep part of the dive \u2013 they use it during decompression stops when ascending from a deep dive.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Pareiza_nitrox_maisijuma_izvele_un_aprikojums\"><\/span>7.
