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 shallowest depth to which a diver may
ascend based on computed nitrogen load.
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".
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.
