Air Nitrox - EANxEnriched
Air Nitrox - EANx
OVERVIEW
This is course is to provide the
diver with the information necessary to utilize EANx as a breathing medium.
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.
The course is offered in two versions:
Computer Nitrox is designed for recreational divers who want to dive computer assisted nitrox diving only. The Basic Nitrox course is a more in-depth look at the origins, development, planning, and usage of nitrox for extended bottom times. Divers who want are interested in working toward technical diving should take the Basic Nitrox course.
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: Openwater 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

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.
