A dive made at an elevation greater than 300 m
[1000 ft] above sea level.
The speed at which the diver ascends toward the
surface.
Abbreviation for ascent rate.
The minimum amount of time needed to reach the
surface on a decompression stop di
Abbreviation for ascent time.
On a decompression stop dive the shallowest depth
to which a diver may ascend based on computer
nitrogen load.
On a decompression stop dive the zone between the
ceiling and the ceiling plus 1.8 m [6 ft]. This depth
range is displayed with the two arrows pointing
toward each other (the "hour glass" icon).
Abbreviation for Central Nervous System toxicity.
Toxicity caused by oxygen. Can cause a variety
of neurological symptoms. The most important of
which is an epileptic-like convulsion which can
cause a diver to drown.
Central Nervous System toxicity limit fraction. Also
note Oxygen Limit Fraction
See "Tissue group".
Divers Alert Network.
Abbreviation for decompression illness.
Time spent at a decompression stop or range before
surfacing, to allow absorbed nitrogen to escape natu-
rally from tissues.
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.
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 decompression. Commonly called "bends"
or "DCI".
