Enriched Air Nitrox Pre-Requisites

To start the Enriched Air Nitrox course you need to be at least 12 years old and certified as a PADI Open Water Diver.

All PADI courses and programs require you to answer a medical questionnaire. Please take a look at the PADI Medical form to find out if you should be examined by your Doctor before participating in Recreational Scuba Diving.

What’s Involved?

During the course you’ll learn why diving with air that has a higher oxygen content and lower nitrogen content will give you longer bottom times. You’ll learn about enriched air equipment considerations and why scuba tanks must meet oxygen service standards and be dedicated for use with EAN. Maximize your fun when diving with enriched air! You will also:

  • Discuss how to manage oxygen exposure during your dives
  • Practice analyzing the oxygen content of your tank
  • Set your computer to dive with enriched air

After watching the PADI Enriched Air Nitrox video and reading your EAN Diver manual you’ll be ready to discuss the course content with your instructor and pass your exam.
