Nitrox
Nitrox, also known as Enriched Air, is a special breathing gas mixture used in scuba diving that contains more oxygen than regular air. It allows divers to stay underwater longer and reduces fatigue after diving. When someone mentions Nitrox certification on their resume, it means they are qualified to both use this gas mixture themselves and, at higher certification levels, teach others how to use it safely. This is an important skill in the diving industry, especially for dive instructors and diving operation managers.
