Oxygen percentage or oxygen fraction in the breathing gas. Standard air
has 21% oxygen.
Limits the maximum depth to which the nitrox mixture can be safely 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 risk
immediate oxygen toxicity.
Abbreviation for oxygen partial pressure.
Abbreviation for Reduced Gradient Bubble Model.
Modern algorithm for tracking both dissolved and free gas in divers.
Any dive whose 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.
Theoretical concept used to model bodily tissues for the construction of
decompression tables or calculations.
Another form of oxygen toxicity, which is caused by prolonged exposure
to high oxygen partial pressures. The most common symptoms are
irritation in the lungs, a burning sensation in the chest, coughing and
reduction of the vital capacity. Also called Pulmonary Oxygen Toxicity.
