Decompression

Time spent at a decompression stop or range
before surfacing, to allow absorbed nitrogen
to escape naturally from tissues.

Decompression range

On a decompression stop dive the depth
range, between the fl oor and ceiling, within
which a diver must stop for some time during
ascent.

Decompression illness Any of a variety of maladies resulting either

directly or indirectly from the formation of
nitrogen bubbles in tissues or body fl uids, as
a result of inadequately controlled decom-
pression. Commonly called “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.

DP

Delta P, describing the Cylinder Pressure
drop during the dive; difference in cylinder
pressure between beginning and end of 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 added. 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 decompression takes
place.
