Enriched Nitrox Course

The Enriched Air Nitrox (EANx) Diver Course is designed to teach certified divers how to safely plan and conduct dives using enriched air, which contains a higher percentage of oxygen than regular air. This allows for extended no-decompression dive times. Here's a general description, itinerary, and requirements for an Enriched Air Nitrox Dive Course:

Course Overview: The Enriched Air Nitrox Diver Course is often offered by scuba diving agencies such as PADI, NAUI, and others. The course aims to educate divers on the benefits, risks, and procedures associated with diving using enriched air blends.


  1. Prerequisites:

    • Participants must be certified divers, typically holding an Open Water Diver certification or an equivalent qualification.

    • Some agencies may require a minimum age for participants (e.g., 12 years old).

  2. Medical Clearance:

    • Participants are required to complete a medical questionnaire. If any medical issues are identified, participants may need to obtain a physician's approval before starting the course.

  3. Classroom Sessions:

    • The course begins with classroom sessions covering the theory of enriched air diving. Topics include the benefits and risks of using enriched air, dive planning, and the effects of oxygen on the body.

  4. Equipment Considerations:

    • Participants learn about the specialized equipment used for enriched air diving, including dive computers capable of handling nitrox mixes and oxygen analysis tools.

  5. Nitrox Dive Tables:

    • Training includes the use of nitrox dive tables to plan dives with different enriched air blends.

  6. Practical Application:

    • Participants practice analyzing the oxygen content of enriched air cylinders.

    • Dive planning exercises to understand how enriched air affects dive profiles.

  7. Safety Procedures:

    • Emergency procedures related to enriched air diving, including managing oxygen exposure, are covered in detail.
