COURSE OVERVIEW
The Nitrox Diver Course is a
comprehensive course that teaches the student practical information needed to
use oxygen enriched air. The course reviews gas, explains the concept of partial
pressure , covers oxygen physiology plus oxygen limits and tolerance techniques,
explains how to select the right mix, and importance of the right amount of
gas.
It includes both procedures and tables
to manage no-stop dives, incorporates dive computers and dive planning software,
reviews mixing and how to obtain enriched air fills, and covers contingency
procedures, as well as presenting an introduction to technical
diving.
Students are trained to accurately
analyze the gas they will be using and to plan open water dives using
the Nitrox dive tables .
Using nitrox lengthens the
amount of bottomtime while minimizing your nitrogen
saturation.
In order to use nitrox a diver
must be trained in its proper uses to insure safety
!
MYTH #
1 : “Nitrox is safer than air.”
“SAFE” to most people
means without risk, but all diving contains a level of risk. Nitrox has
significant decompression advantages over air; but to take advantage of those benefits other risks, (oxygen
toxicity, time and depth limits) must be weighed. When all are managed
properly, the risks are minimal.
MYTH #
2 : “Nitrox is for deep diving.”
Nitrox has very
stringent depth limits due to the higher concentration of oxygen in
the mixture.
The two standard mixtures EAN 32 and EAN
36 have maximum depths of 110 ft and 90 ft respectively.
MYTH #
3 : “You can’t get decompression sickness.”
No computer or following the dive
tables can absolutely ensure that a diver will not get decompression sickness.
Using nitrox provides significant decompression advantages over air, but with
all diving there is a risk of developing DCS. By using nitrox a diver is
minimizing the risks while maximizing diving enjoyment.
MYTH # 4
: “Narcosis is eliminated.”
It might seem logical that with
reduced nitrogen in the breathing mix there would be reduced nitrogen narcosis
at depth. The fact is, oxygen can also be a narcotic gas when under pressure.
The result is that there is NO significant change in narcosis when diving nitrox
compared to air.
MYTH #
5 : “Using Nitrox is difficult.”
Some of the procedures in the planning
and preparation process are a bit more involved than for air diving, but they
are designed to help you have a relatively low-risk and enjoyable dive.
