Reduced Gradient Bubble Model

From Wikipedia, the free encyclopedia

The RGBM is a Dr Bruce Wienke's algorithm, based on Varying Permeability Model, that is used to calculate the decompression stops needed for a particular dive profile.

It is used in several dive computers, particularly those made by Suunto, Mares, HydroSpace Engineering and Underwater Technology Center. It is characterised by the assumption of asymmetric offgassing and compensation for nitrogen microbubbles, which can reduce the rate of offgassing.
