Workman65: Decompression model of Workman 1965

In scuba: Diving Calculations and Decompression Models

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:

halftime	Nitrogen halftime (minutes)
M0	surfacing M-value parameter M0 in msw (metres of seawater)
A	slope parameter A (dimensionless)

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.
