BUBBLE DECOMPRESSION PROGRAM

With more divers pulling deep decompression stops, discussions have centered around techniques for setting stop depths and times. Nonetheless, few people have a copy of the so-called Hawaiian "Tiny Bubble" model at their disposal. I'll put the source code for a simplified version of the Varying Permeability Model¹ up on this site soon. Are you interested in a preview? I'm looking for reviewers to catch bugs, etc.

This is NOT a dive deco calculator, but the source code intended for intelligent users who want to learn how deco stops are set by the VPM. For reasons of transparency and ease of convertibility, the language is the old Microsoft QUICK-BASIC (or QBasic), which work in DOS mode. If you don't program, then this is probably not for you. Even if you do, my style may not be for you either ; >

An example of a VPM ascent schedule is shown in the Santa Barbara Alps article.

If you want a copy of the Basic code and a text list-file, please make the following statements in an email to me at emaiken@gol.com:

• State explicitly that you understand that the program is only to implement the algorithm of reference 1 below.
• State explicitly that you will not use the program to calculate actual decompression schedules for dives.
