The parameters of the decompression model due to Workman, 1965.
A data frame giving the following parameters for each compartment:
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.
