Data for several decompression models of Haldane type, giving the tissue halftimes for Nitrogen and the M-values (maximum tolerated partial pressure of Nitrogen for surfacing).
The dataset Bookspan is a list with the following entries:
Halftimes data. A list with entries
Haldane | halftimes for Haldane's original model |
USN | halftimes for US Navy original model |
DSAT | halftimes for DSAT model |
OrcaEdge | halftimes for OrcaEdge computer |
MicroBrain | halftimes for MicroBrain computer |
ZHL12 | halftimes for ZH-L12 model |
surfacing M-values in ata (atmospheres absolute). A list with entries
Haldane | M-values for Haldane's original model |
USN | M-values for US Navy original model |
DSAT | M-values for DSAT model |
surfacing M-values in fsw (feet of seawater).
A list with the same structure as Mvalues.fsw.

Bookspan (1995) tabulates the parameters of several different decompression models of the classical Haldane type. The basic parameters for such a model are
the Nitrogen diffusion halftime (in minutes) for each tissue in the model
the maximum partial pressure of Nitrogen in each tissue which would be tolerated without symptoms at an ambient pressure of 1 atmosphere (the ``surfacing M-value'').
The data tabulated in Bookspan (1995, page 16) purportedly give the halftimes for Haldane's original model, the original US Navy model, the DSAT model (basis of PADI repetitive dive planner), the OrcaEdge, MicroBrain and Aladin dive computers, and the Buehlmann ZH-L12 model.
The data tabulated in Bookspan (1995, page 23) give the corresponding M-values (in fsw) for the US Navy and DSAT models only.
These parameters are all contained in the dataset Bookspan.
