  We present some experimental and simulation results that reproduces the
Ostwald ripening (gas diffusion among bubbles) for air bubbles in a liquid
fluid. Concerning the experiment, there it is measured the time evolution of
bubbles mean radius, number of bubbles and radius size distribution. One of the
main results shows that, while the number of bubbles decreases in time the
bubbles mean radius increases, hence, it follows that the smaller bubbles
disappear whereas the -- potentially dangerous for the diver -- larger bubbles
grow up. Consequently, this effect suggests a possible contribution of the
Ostwald ripening to the decompression sickness, and if so, it should be pursued
its implementation to the Reduced Gradient Bubble Model (RGBM) so as to build
up dive tables and computer programs for further diving tests.
