Henry's Law - (answer)The amount of gas dissolved in a liquid is directly related to its partial pressure
above the liquid.
Relationship of gas solubility and temperature - (answer)Solubility of gas decreases with increasing
temperature
(INVERSELY RELATED)
Inert gas loading in relation to body tissue - (answer)Body tissue absorbs more inert gas as depth
increases
Benefit of Dive Computer compared to Dive Tables - (answer)Gives the diver credit for shallow portions
of the dive
Cold or Strenuous dive planning rule - (answer)Use the next greater dive TIME to determine letter group
Equilibrium as it relates to nitrogen in the body - (answer)When the pressure of nitrogen is balanced
between air and your body
Haldane surfacing ratio - (answer)Originally 2:1 - Updated with new research to 1.58:1
Tissue compartment half-time - (answer)The time required for the compartment to absorb or eliminate
half of the pressure difference between what it started with and the ambient pressure
M-Value of tissue - (answer)The maximum allowable nitrogen (inert gas) pressure in a specific tissue
NAUI recommendation for diving while pregnant - (answer)Do not dive while pregnant
Haldane tissue compartments - (answer)Haldane - 5 compartments

Tissue compartment - (answer)Mathematical model consisting of multiple theoretical tissues and their
relative halftimes
Fast compartments - short halftimes
Slow compartments - long halftimes
Ascent rate at altitude - (answer)Slower than at sea level
Extend dive times with gas by - (answer)Decreased nitrogen and increased oxygen in breathing gas
RNT - (answer)Residual Nitrogen Time
Tme already spent at the repetitive dive depth (dive tables)
Procedure for missed decompression stops - (answer)Remain out of the water, rest, breathe 100%
oxygen, drink fluids, be monitored for signs of decompression illness, transported to a hyperbaric facility
if symptoms arise
SIT - (answer)Surface Interval Time
Longer time at the surface allows for increased repeat dive times
Canadian Dive Tables published by the Defense and Civil Institute of Environmental Medicine (DCIEM) -
(answer)Based on 20+ years of research pioneered by Kidd and Stubbs (1962)
Swiss Dive Tables - (answer)Developed by A.A. Bühlmann at the University of Zurich - EXTENDED TO
INCLUDE ALTITUDE DIVING
If the time spent making a "precautionary stop" at 5 msw (15 fsw) causes your Total Dive Time to exceed
the Dive Time Limits, you should: - (answer)Use the Maximum Dive Time as your Total Dive Time
