The amount of dive time remaining, based on a calculation of cylinder pressure and ambient pressure and present air consumption.
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.
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 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
Central nervous system toxicity limit fraction. Also note Oxygen Limit Fraction
