V-Planner and the decompression schedules it produces are tools for experienced mixed-gas decompression divers ONLY. Deep diving utilizing multiple gasses, including helium, or rebreathers is about as risky as it gets. Diving in general is fraught with risk, and decompression diving adds significantly more risk. This dive schedule is experimental and you use it at your own risk. 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. You're expected to know the theory behind the diving practices and procedures used here. If you're relatively new to diving, you may find this program difficult to use. Please note - this program is made with the experienced and technical diver in mind. The V-Planner program was developed by Ross Hemingway, and presents the VPM-B algorithm inside a complete and useful Windows dive decompression program. In 2002, after considerable diver feed back, the model was further developed by Erik Baker, to the current VPM-B model. It was further developed by David Yount, Eric Maiken, and Erik Baker from 1999 to 2001. The Varying Permeability Model was originally developed by Yount and Hoffman in 1986. The super saturation gradient is sufficient to probe the laplace condition Stabilize free phase gas and that can grow into full fledged extravascular bubbles when These are the microscopic physical structures that These super saturation gradients areĭetermined by tracking sets of VPM nuclei (bubble seeds) of a certain
In VPM, ascent ceilings are determined on allowable gradients for bubbleįormation rather than M-values. The output of aīubble model is similar to many established deep practices suchĪs Pyle Stops, Florida cave practices, DIR, ratio deco plans and others. Measure micro bubble growth, and set limits accordingly. The VPM bubble model uses math to simulate and Technical and deep diving, with many training agencies including bubble The Bubble models and similar deep stop profiles, have become the standard for V-Planner is available for PC, Mac, Linux, Android, iPad, iPhone. The settings allow for customized deep and extended stops, control stop times, airbreaks. Includes Gas Mixer, Turn pressure formula, Layouts for saving complex dive plans, Graphs, data export, etc. V-Planner makes plans for Lost deco gas, Turn pressures, Range plans, RB bail outs, watches and warnings. V-Planner calculates all types of Nitrox, Trimix, TriOx, HeliOx, OC, SCR, CCR, RB80, KISS and multilevel dives. The VPM model is the most widely used bubble model by tech divers today.
