Modeling phase volume constraints under repetitive decompression (Q1197068)

Extending the critical volume hypothesis in time integral form to repetitive decompressions, the author shows that reduced gradients following repetitive exposures are necessary in time, in any model, to maintain the separated nitrogen in tissue (bubbles) below a limit point. A model called the reduced gradient bubble model is described and applied to a marginal multi-day profile, illustrating systematic reductions in gradients, and hence non-stop time limits, across individual segments.
