The VPM model is the most widely used bubble model by tech divers today. MultiDeco calculates all types of Nitrox, Trimix, TriOx, HeliOx, OC, SCR, CCR, RB80, KISS and multilevel dives. MultiDeco makes plans for Lost deco gas, Turn pressures, Range plans, RB bail outs, watches and warnings. Includes Gas Mixer, Turn pressure formula, Layouts for saving complex dive plans, Graphs, data export, etc. The settings allow for customized deep and extended stops, control stop times, airbreaks. Antonio Jose Sonata Pdf Converter. MultiDeco is available for PC, Mac, Android, iPad, iPhone.

The Bubble models and similar deep stop profiles, have become the standard for technical and deep diving, with many training agencies including bubble models into thier courses. The VPM bubble model uses math to simulate and measure micro bubble growth, and set limits accordingly. The output of a bubble model is similar to many established deep practices such as Pyle Stops, Florida cave practices, DIR, ratio deco plans and others. In VPM, ascent ceilings are determined on allowable gradients for bubble formation rather than M-values. These super saturation gradients are determined by tracking sets of VPM nuclei (bubble seeds) of a certain initial critical radius. These are the microscopic physical structures that stabilize free phase gas and that can grow into full fledged extravascular bubbles when the super saturation gradient is sufficient to probe the laplace condition for bubble formation.

Decompression software which uses a VPM bubble model with deep stops inbuilt. Green Valley Dog Drivers more. Can set conservatism levels, create lost gas and bail out plans, extended stops, and air. Decompression model comparisons and history of decompression developement including VPM, RGBM, VPM-B, Weinke, Yount and Buhlmann for decompression software.

The Varying Permeability Model was originally developed by Yount and Hoffman in 1986. It was further developed by David Yount, Eric Maiken, and Erik Baker from 1999 to 2001. In 2002, after considerable diver feed back, the model was further developed by Erik Baker, to the current VPM-B model. The MultiDeco program was developed by Ross Hemingway, and presents the VPM-B algorithm inside a complete and useful Windows dive decompression program. Please note - this program is made with the experienced and technical diver in mind.

If you're relatively new to diving, you may find this program difficult to use. You're expected to know the theory behind the diving practices and procedures used here. ********* WARNING & DISCLAIMER ********* The author and HHS Software Corp do not warrant that this program accurately reflects the Varying Permeability Model algorithms, or that it won't get you bent or dead, or that it will produce safe, reliable results. This dive schedule is experimental and you use it at your own risk. Diving in general is fraught with risk, and decompression diving adds significantly more risk. Deep diving utilizing multiple gasses, including helium, or rebreathers is about as risky as it gets. MultiDeco and the decompression schedules it produces are tools for experienced mixed-gas decompression divers ONLY.
