[Simulation of tissue nitrogen supersaturation and the risk of tissue lesion by gas bubbles at non-stop dives].
The given study shows that a relationship between the coefficients of critical nitrogen supersaturation of theoretical tissues and the values of their nitrogen wash in and washout half-times can be mapped into a curve that goes around the family of curves that define the degree of tissue nitrogen supersaturation after extremely safe non-stop dives from the surface with air as breathing mixture. Our calculations of the growth dynamics of gas bubbles formed in theoretical tissues after these dives indicate that the sizes of tissue bubbles are not in themselves a measure of the risk of developing decompression sickness (DCS). At the same time, the original probabilistic model of the DCS proposed by us previously shows that the risk of lesion of any real tissue by bubbles and appearance of the appropriate DCS symptoms depends on the size of gas bubbles as well on their density and tissue volumes. The theoretical analysis of specific character for the risk of lesion of various body tissues by gas bubbles at equiprobable safe non-stop dives was carried out in the context of this model.
