Varying Permeability Model construct an algorithm that provides decompression schedules designed to allow the larger, growing bubbles to be eliminated before they can cause problems. This bibliography list was compiled by E.B. Maiken and E.C. Baker as reference material for the V-Planner web site in 2002. Varying Permeability Model The Varying Permeability Model, Variable Permeability Model or VPM is an algorithm that is used to calculate the decompression stops needed for a particular dive profile. It was developed by D.E. Yount and others for use in professional diving and recreational diving. It was developed to model laboratory observations of bubble formation and growth
