Details

The decompression model developed for the US Navy by Workman (1965) is a pure diffusion (Haldane-type) model consisting of 9 tissue compartments. Nitrogen in the breathing gas diffuses in and out of each compartment at a rate governed by the halftime for that compartment. The maximum tolerable nitrogen tension in a compartment, when the diver is at depth $D$ msw (metres of sea water), is $M = M0 + A * D$ msw, where $M0$ and $A$ are values intrinsic to the tissue. The value $M0$ is called the `surfacing M-value' since it is the maximum nitrogen tension that is allowed in each compartment during a no-decompression dive at sea level.
