What Is Nitrox Anyway?|
Date:09/19/02 By SanDiegoDiving.com Editorial
What is it?
Other common terms for nitrox include Enriched Air, OEA (Oxygen Enriched Air), EAN (Enriched Air Nitrox) and EANx (Enriched Air Nitrox).
Why would a diver use nitrox?
How does nitrox work?
With nitrox, a percentage of nitrogen in the breathing gas mix is replaced with oxygen, thus decreasing the risk of decompression sickness that would be present if air was used on the same dive profile.
Who should dive using nitrox?
Why not use nitrox?
Divers and nitrox fill stations both require specialized training and equipment to work with nitrox. These requirements increase preparation time requirements and suppliers generally charge more to supply divers with nitrox as opposed to air as a result.
Divers using nitrox assume a greater risk of oxygen toxicity than they would using air. To manage this risk, divers using nitrox must use particular caution to avoid excess exposure to oxygen under pressure. As a result, it is extremely important to abide by strict depth and time limits that differ by the oxygen mixed being used. Accordingly, these procedures add tasks to pre-dive planning and introduce new and potentially hazardous risks to manage while diving.
Where can I find nitrox?
It is strongly advisable to obtain nitrox fills only from reputable filling stations that have proof of special training.
