Congratulations, Kathryn Britnell - You're A Nitrox Diver Now!

Kathryn passed her PADI Enriched Air Nitrox (EAN) Speciality Course this week which will now allow her to dive for a longer time at a given depth without an increased risk of decompression sickness.

Nitrox specifically denotes a gas mixture that has a higher percentage of oxygen than normal air (more than 21% oxygen); it is essentially air that has been "enriched" with additional oxygen. While EANx may contain any percentage of oxygen greater than 21%, the most common mixtures for scuba diving are EANx 32 (NOAA Nitrox 1) and EANx 36 (NOAA Nitrox II) which have 32% and 36% oxygen respectively. Special training and certification and required to dive with EANx.

Way to go, baby!
