Title: [abstract] TINY BUBBLE HELIUM DECOMPRESSION TABLES.
Author: Hoffman, DC; Yount, DE
Abstract: In the past, decompression tables for humans have been based upon unsupported assumptions because the underlying processes by which dissolved gas is liberated from blood and tissue were poorly understood. Some of those assumptions are now known to be wrong, and the recent formulation of a detailed mathematical model describing bubble nucleation has made it possible to calculate diving tables from established physical principles. To evaluate this approach, a comprehensive set of air diving tables was developed and compared with those of the U.S. and British Navies. Conventional decompressions, altitude bends, no-stop thresholds, and saturation dives were all successfully described by one setting of four global nucleation parameters, which replaced the U.S. Navy's matrices of M-values. The latest application of the nucleation model extends these tables to include simple helium dives. Comparing the total decompression times required for various bottom times in conventional air and helium tables shows great irregularity, not only from one set to another, but even within sets produced by the same authors. In contrast, this new approach is remarkably self-consistent, permitting accurate interpolation and extrapolation, and it has a wide range of applicability, extending from no-decompression to saturation dives.
