How much does the constant of proportionally differ from 1.58?
Your response is fine for those who understand this stuff. The OP is trying to understand it, he not there yet. Why don't you help him rather than making fun of my gentle rhetorical attempts to help?A table with all deltaM values (they differ by tissue) is in the referenced file you posted above: Table 1
Just saying.

In order to on-gas a compartment, there should be a differential pressure between the outside pressure and the pressure in the compartment. The same to off-gas. So, to off-gas a compartment the outside should have a lower pressure than the compartment. If the outside pressure is too low the gas in the compartment can start to form bubbles. The M-value is the maximum differential pressure that a compartment can withstand without forming bubbles during the off-gassing process.
This M-value depends on the compartment and the pressure. Workman modelized this as a linear function for each compartment.
Buhlmann's a and b coefficients were, according to Powell, calculated as
a = 2 * t ^ -1/3
b = 1.005 - t ^ -1/2
("A" set). There is no explanation, in Baker or elsewhere, that I could find, of which of those 4 numbers are "tolerated surplus volumes" and which: "gas solubilities".
I am just trying to understand the concept of "tolerated surplus volumes", no need for a mathematical definition
