Decompression illness

Any of a variety of maladies resulting either directly or indirectly from the

formation of nitrogen bubbles in tissues or body fluids, as a result of inad-

equately controlled decompression. Commonly called "the bends" or

"DCI".

Dive series

A group of repetitive dives between which the dive computer indicates

some nitrogen loading is present. When nitrogen loading reaches zero

the dive computer deactivates.

Dive time

Elapsed time between leaving the surface to descend, and returning to

the surface at the end of a dive.

EAD

Abbreviation for equivalent air depth.

EAN

Abbreviation for enriched air nitrox.

Enriched air nitrox

Also called nitrox or Enriched Air = EANx. Air that has some oxygen ad-

ded. Standard mixes are EAN32 (NOAA Nitrox I = NN I) and EAN36

(NOAA Nitrox II = NN II).

Equivalent air depth

Nitrogen partial pressure equivalent table.

Floor

The deepest depth during a decompression stop dive at which decom-

pression takes place.

Half time

After a change in ambient pressure, the amount of time required for the

partial pressure of nitrogen in a theoretical compartment to go half way

from its previous value to saturation at the new ambient pressure.

MOD

The maximum operating depth of a breathing gas is the depth at which

the partial pressure of oxygen (PO2) of the gas mix exceeds a safe limit.
