Any dive whose decompression time limits are affected by residual nitro-
gen 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 irrita-
tion in the lungs, a burning sensation in the chest, coughing and reduction
of the vital capacity. Also called Pulmonary Oxygen Toxicity. See also
