    Multi-Exponential washout models. How to measure risk? DCS risk is intrinsically probabilistic and, not deterministic, in other words, there is no mathematical critical point in which you “can or can’t” get DCS. The risk changes continuously and gradually with decompression stress. Deterministic models work with compartments and base the decompression on a leading compartment in…

    Understanding nucleation as a process and what divers can do to mitigate it.

    Divers have a generalized concept that decompression bubbles form with ascent and reduced its sizes with a decrease in ambient pressure but this isn’t completely accurate, tiny microbubbles are already present prior depressurization. Which means that two factors should be present for the occurrence of DCS, micronuclei and supersaturation. Although our internal body have no…
