EAN

Abbreviation for enriched air nitrox.

Enriched Air Nitrox

 

 

Oxygen-Nitrogen mix, normally with more than 21% oxy-

 

gen.

Freediver

A breath-holding diver whose only source of oxygen are his

 

lungs filled with surface air.

Hypercapnia

Increased amount of carbon dioxide in the blood. A diver

 

who does not rest adequately between breath-hold dives

 

will have elevated carbon dioxide levels. This can pre-

 

dispose hin to carbon dioxide toxicity or blackout.

Hyperventilation

An increase in rate and/or volume of breathing. Carbon

 

dioxide blood levels decrease with little corresponding

 

increase in oxygen blood levels. If the diver engages in

 

excessive hyperventilation, he may diminish his desire to

 

breathe, long enough to become unconscious after a long

 

period of apnea.

Hypoxia

A condition that occurs when a diver’s tissues do not re-

 

ceive enough oxygen. Freedivers become hypoxic when

 

they hold their breath; they can eventually suffer blackout

 

if they hold their breath too long.

MOD

Abbreviation for Maximum Operating Depth. The maxi-

 

mum depth at which gas is breathable with selected PO2

 

limit.
