NAUI NITROX exam with
verified solutions
What is nitrox? - answer Fraction of nitrogen is reduced, oxygen
increased,
also called EANx for example EAN32 (32% oxygen)
Reducing amount of nitrogen means you can dive ------ to a given depth or
reduce ----- between dives - answer longer, required surface interval
excess nitrogen is the cause of ----- - answer decompression sickness
Development of Nitrox began in what year? The same year the first diving
decompression tables were published - answer 1908
What year did NAUI indorse EANx and official accept certifications from
two specialized nitrox training agencies - answer 1992
What year did NAUI codify standards for enriched air nitrox training and
certification? - answer 1996
Advantages of nitrox include...
-extended bottom times
-shorter surface intervals
increased safety factor when used with air tables
true or false? - answer true
TRUE or FALSE
, Nitrox is the same as trimix and its used to reduce the effects of narcosis
that a diver might feel. - answer FALSE
Other terms for NOAA Nitrox I and II - answer I=EAN32, II-EAN36
TRUE or FALSE
All of these terms refer to the same breathing mixture
- EAN36
NOAA Nitrox II

Nitrox provides the greatest advantages for dives in the _____ depth range.
- answer 15-33 m (50-110ft) depth
Pressure of gas is dependent on how the molecules strike the container,
pressure can be increased by____ it into a smaller container and by
increasing ____ - answer compressing, temperature
More gas will dissolve at____ temperatures. The amount of gas that will
dissolve in the liquid is directly proportional to the ____ of the gas on the
liquid - answer Lower, pressure
TRUE OR FALSE
Air is mostly composed of oxygen and othe rmiscellaneous gases with the
least abundant gas being nitrogen (N2) - answer FALSE
