Abbreviation for ascent rate.
The minimum amount of time needed to reach the
surface on a decompression dive.
Abbreviation for ascent time.
On a decompression dive the shallowest depth
to which a diver may ascend based on computer
nitrogen load.
On a decompression dive the zone between the

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 can cause a diver to
drown.
Central Nervous System toxicity limit fraction. Also
