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 M_0 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 = 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.
