Workman65: Decompression model of Workman 1965
Description
The parameters of the decompression model
due to Workman, 1965.format
A data frame giving the following parameters for each compartment:
ll{
halftime Nitrogen halftime (minutes)
M0 surfacing M-value parameter $M_0$ in msw (metres of seawater)
A slope parameter $A$ (dimensionless)

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
$M = M_0 + A \times D$
msw, where $M_0$ and $A$ are values intrinsic to the tissue.
The value $M_0$ 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.References
