What does RGBM mean in dive computers?
Diving models address the coupled issues of gas uptake and elimination, bubbles, and pressure changes in different
computational frameworks. Application of a computational model to staging divers is called a diving algorithm. The
Reduced Gradient Bubble Model (RGBM) is a modern one, treating the many facets of gas dynamics in tissue and
blood consistently. Though the systematics of gas exchange, nucleation, bubble growth or collapse, and decompression
are so complicated that theories only reflect pieces of the decompression sickness (DCS) puzzle, the risk and statistics
of decompressing divers are straightforward. And folding of DCS risk and statistics over data and model assumptions
is perhaps the best means to safety and model closure.
