Decompression model ZH-L16A

Description

The parameters of the decompression model ZH-L16A developed by Buehlmann.

Format

A data frame giving the following parameters for each compartment:
id compartment name (1, 1b, 2, ..., 16)
halftime Nitrogen halftime (minutes)
a parameter a in ata (atmospheres absolute)
b parameter b (dimensionless)

Details

Buehlmann's decompression model ZH-L16A is a pure diffusion (Haldane-type) model consisting of 17 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 ambient pressure is P atmospheres absolute, is

Ptol = a + P/b

where a and b are values intrinsic to the tissue. Thus, for a no-decompression dive at sea level, the nitrogen tension in each compartment must not exceed the value a + 1/b for that compartment.
