The cost of Nitrox fills is generally about 1.5 the amount of air fills. He or she must present a Nitrox certification card when having tanks filled. Some divers also feel that using Nitrox will lessen the chances of getting nitrogen narcosis at depth.ДЄ diver must be certified in order to use Nitrox. Most divers report that they feel less tired after diving with Nitrox than they do after diving with air. This is how Nitrox got the nickname 'geezer gas'. Historically, some of these divers have been overweight, out of shape, elderly or have suffered DCS previously. In other words, on any given dive they reduce the amount of nitrogen that is being absorbed by using Nitrox, but they do not extend the bottom times of their dives or shorten their surface intervals. They accomplish this by diving with Nitrox, but using air tables instead of Nitrox tables. Some divers also use Nitrox to try to lessen the chances of getting DCS. By using EAN 36 a person diving to 90 feet can nearly double the length of the dive, when compared to breathing regular air (see the 'Comparison Of Dive Times' table below).Дecompression sickness (DCS) occurs when there is excess nitrogen in the body.

Using the figure of 1.4, the MOD for EAN 32 is 110 feet and 90 feet for EAN 36. Many divers strongly suggest a maximum P02 of 1.4 (or less). When Nitrox is mentioned but the mix is not known, it is usually expressed as EANx. For example, EAN32 is a mix that contains 68% nitrogen and 32% oxygen. The number following 'EAN' is the percentage of oxygen in the mix. 'EAN' is an abbreviation for Enriched Air Nitrox. 'P' is an abbreviation for 'partial pressure', and 'O2' is the chemical symbol for oxygen. Navy Diving Manual, as well as the NOAA Manual. The maximum pressure of 1.6 atmospheres (ATM) is often quoted for Nitrox diving, since it is referenced in the U.S. As the percentage of oxygen in the mix increases, the maximum operating depth decreases (becomes shallower). The MOD of a given mixture varies depending on the maximum partial pressure of oxygen to which a diver wishes to be exposed. Therefore, every Nitrox mixture has a maximum operating depth (MOD). This is also referred to as oxygen toxicity ('oxtox') or oxygen poisoning. As the partial pressure of oxygen reaches certain levels in the body, central nervous system (CNS) toxicity can occur. 'Partial Pressure' is the pressure exerted by a gas in a mixture of gases. In addition, since less nitrogen is being absorbed on any given dive, the surface interval between dives can usually be shortened. By increasing the amount of oxygen and reducing the amount of nitrogen in the breathing gas, the maximum allowable bottom time is increased. Nitrox is a special blend of air than contains more oxygen (and less nitrogen) than the air we normally breathe, and it has become increasingly popular among scuba divers in recent years. It is the same as the air we breathe and the percentage of each gas in the mixture is about 79% nitrogen and 21% oxygen.

Others were obtained from an on-line Nitrox calculator. Some of the values listed below were calculated from US Navy Dive Tables and NOAA Nitrox Tables.
