The amount of dive time remaining, based on
a calculation of cylinder pressure and
ambient pressure and present air consump-
tion.
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
dive.
Abbreviation for ascent time.
On a decompression stop dive the shallow-
est 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.
