Mvalues {scuba} | R Documentation |
Contains the surfacing M-values (maximum surfacing nitrogen tensions) for several Haldane-type decompression models.
A list with two components called ata
and fsw
,
giving the surfacing M-values in atmospheres absolute
(ata
) or in equivalent feet of seawater (fsw
)
respectively.
Each component is a list of three vectors, named
Haldane | J.S. Haldane's original model |
USN | original US Navy model |
DSAT | model for DSAT (PADI) tables |
containing the M-values for the
tissues in the relevant model, listed from fastest to slowest.
The tissues correspond to the tissues in the dataset
Halftimes
.
The surfacing M-value (in the terminology of Workman) is the maximum partial pressure of inert gas in a tissue compartment which would be tolerated without symptoms of decompression sickness at an ambient pressure of 1 atmosphere.
This dataset gives the surfacing M-values for nitrogen in each tissue, in several of the classical decompression models, as tabulated by Bookspan (1995, page 23).
