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 floor 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 fluids, 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.
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
