The amount of gas dissolved in a liquid is directly
Henry's Law
related to its partial pressure above the liquid.
Solubility of gas decreases with increasing
Relationship of gas
temperature
solubility and temperature
(INVERSELY RELATED)
Inert gas loading in Body tissue absorbs more inert gas as depth
relation to body tissue increases
Benefit of Dive Computer Gives the diver credit for shallow portions of the dive
compared to Dive Tables
Cold or Strenuous dive Use the next greater dive TIME to determine letter
planning rule group
Equilibrium as it relates to When the pressure of nitrogen is balanced between
nitrogen in the body air and your body
Haldane surfacing ratio Originally 2:1 - Updated with new research to 1.58:1
The time required for the compartment to absorb or
Tissue compartment half-
eliminate half of the pressure difference between
time
what it started with and the ambient pressure
The maximum allowable nitrogen (inert gas) pressure
M-Value of tissue
in a specific tissue
, NAUI recommendation for Do not dive while pregnant
diving while pregnant
Haldane tissue Haldane - 5 compartments
compartments Modern Computers - Apx. 16 compartments
Mathematical model consisting of multiple theoretical
tissues and their relative halftimes
Tissue compartment
Fast compartments - short halftimes
Slow compartments - long halftimes
Ascent rate at altitude Slower than at sea level
Extend dive times with gas Decreased nitrogen and increased oxygen in
by breathing gas
Residual Nitrogen Time
RNT Tme already spent at the repetitive dive depth (dive
tables)
Remain out of the water, rest, breathe 100% oxygen,
Procedure for missed drink fluids, be monitored for signs of decompression
decompression stops illness, transported to a hyperbaric facility if
symptoms arise
Surface Interval Time
SIT Longer time at the surface allows for increased repeat
dive times
Canadian Dive Tables Based on 20+ years of research pioneered by Kidd
published by the Defense and Stubbs (1962)
and Civil Institute of
Environmental Medicine
(DCIEM)
Developed by A.A. Bühlmann at the University of
Swiss Dive Tables
Zurich - EXTENDED TO INCLUDE ALTITUDE DIVING
