As a diving expert with extensive knowledge of various breathing gases, I can tell you that the depth you can dive with Nitrox depends on the specific mix of oxygen and nitrogen in the gas. Nitrox is a term used for any gas mixture that contains more oxygen and less nitrogen than air. The most common Nitrox mixtures are Enriched Air Nitrox (EAN), which typically has an oxygen content of 21% to 40%.
When using Nitrox, the
maximum operating depth (MOD) is determined by the percentage of oxygen in the mix. The higher the oxygen content, the deeper you can go before reaching the limit of safe oxygen exposure. However, it's crucial to remember that the MOD is not the same as the "no decompression limit" (NDL) or "maximum depth." The MOD is the depth at which the partial pressure of oxygen in the mix equals the maximum allowed for that specific Nitrox blend, beyond which you must ascend to avoid oxygen toxicity.
To calculate the MOD, divers use dive tables or dive computers that are programmed to account for the specific Nitrox mixture. Divers must be trained in the use of Nitrox and understand the risks associated with its use, including oxygen toxicity and the potential for an accelerated rate of nitrogen absorption at greater depths.
It's also important to note that Nitrox should only be used by certified divers who have received proper training and are using equipment designed for Nitrox use.
