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 decom-
pression stop dive.
Abbreviation for ascent time.
On a decompression stop dive, the shallowest depth to which a diver may
ascend based on computed nitrogen load.
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.
Abbreviation for central nervous system toxicity.
Central nervous system toxicity limit fraction. Also note Oxygen Limit
Fraction
See "Tissue group".
Abbreviation for Divers Alert Network.
Abbreviation for decompression illness.
Time spent at a decompression stop, or range, before surfacing, to allow
absorbed nitrogen to escape naturally from tissues
On a decompression stop dive, the depth range between the floor and
the ceiling within which a diver must stop for some time during ascent.
