 The
EANx Diver
This is course the to provide the diver with the information necessary
to utilize EANx as a breathing medium.
Course prices begin at
$150.
ACADEMIC REQUIREMENTS
The following topics are to be covered: history of nitrox as a breathing
gas; Dalton’s law of partial pressures; physiology of oxygen
and nitrogen; depth limits, advantages, disadvantages and risks of
nitrox; oxygen toxicity; hazards and precautions of handling oxygen;
the concept of Equivalent Air Depth; use of EANx with Standard Air
Dive Tables; common gas mixing procedures; and gas analyzing procedures.
PREREQUISITES FOR ENTERING THE COURSE
- Age. Minimum
is 15 years.
- Certification: NAUI Scuba Diver certification
or the equivalent is required unless combined with the Scuba Diver
course.
The instructor
is to ensure adequate student knowledge and capability before

OVERVIEW
The course may be taught as
a stand-alone specialty course to certified divers or the knowledge
and skills training may be integrated into the NAUI Scuba Diver course.
QUALIFICATIONS OF GRADUATES
Upon successful completion of this course, graduates are considered
competent to utilize EANx in open water diving activities without direct
supervision, provided the diving activities and the areas dived approximate
those of training.
COURSE POLICIES
- Dives shall not exceed
a depth of 130 fsw (40 msw) or 1.6 atm PO2 , whichever is less. No
planned dives requiring actual decompression
stops on the appropriate EANx tables are to be permitted. (Maximum
PO2 of 1.4 is to be taught with 1.5-1.6 as contingencies.)
- This course
may be taught as a NAUI Recognition Program if the open water training
dives are not included. Recognition may be upgraded
to EANx Diver certification upon completion (within six months)
of the required dives under supervision of a NAUI EANx Instructor.
SKILL REQUIREMENTS
At least two dives are to made using EANx, one of which is to be a
repetitive dive. The student is to analyze his or her own breathing
mixture and to plan and safely execute each dive.
