exposure. A combination of CNS% and OTU%.
Oxygen percentage or oxygen fraction in the
breathing gas. Standard air has 21% oxygen.
Limits the maximum depth to which the used Nitrox
mixture can safely be used. The maximum partial
pressure limit for enriched air diving is 1.4 bar. The
contingency partial pressure limit is 1.6 bar. Dives
beyond this limit have the risk for immediate oxygen
toxicity.
Abbreviation for oxygen partial pressure.
Abbreviation for Reduced Gradient Bubble Model.
Modern algorithms for tracking both dissolved and
free gas in the tissues of divers performing a wide
variety of maneuvers.
Any dive whose no-decompression time limits are
affected by residual nitrogen absorbed during
previous dives.
The amount of excess nitrogen remaining in a diver
after one or more dives.
Abbreviation for surface interval time.
Elapsed time between surfacing from a dive and
beginning a descent for the subsequent repetitive
dive.
