NAUI Nitrox Diver
Exam Coverage
Exam coverage for the NAUI Nitrox Diver Exam includes the essential
knowledge and practical competencies required for safe diving with
enriched air nitrox (EANx). It focuses on the properties of oxygen and
nitrogen, gas laws, partial pressure concepts, and the physiological
effects of breathing higher oxygen concentrations underwater. The
exam evaluates understanding of oxygen exposure limits, oxygen
toxicity (CNS and pulmonary), nitrogen absorption, and how nitrox
affects no-decompression limits and dive planning.
,in the early twentieth century, a quantitative model for nitrogen
loading and dive tables were developed by
John Scott Haldane
the ______ in the air you are breathing limits the time you can stay at
depth
nitrogen
we say that nitrogen is an inert gas. this means
our bodies do not use the nitrogen we breathe
, credit for developing and introducing nitrox diving techniques for
standard scuba goes to
Dr. Morgan Wells
NAUI sanctioned enriched air nitrox training in
1992
two benefits of diving with nitrox are
longer dive times and shorter surface intervals
