Bruce Wienke. Bob Swan takes a slightly different approach. Dr. Wienke, responsible for programmes in the national laboratory simulation of nuclear weapons and calculations of Los Alamos (LANL), became interested in the calculations on the decompression and the implementation of models, transmission of gases, and mechanical phases. He was who developed the model of gradient of reduced bubble (RGBM), a double phase method that facilitates the rise of the diver in the most varied conditions of immersion: immersion in altitude, dive without stops, with stops, during several days, dives, at multiple depths, mixtures, and saturation. Air is mainly composed of 78% nitrogen (N2), 21% oxygen (O2) and 1% argon (Ar), although it also contains carbon dioxide (CO2) and trace amounts of other gases.

When we dive, we metabolizamos oxygen, whereas nitrogen, that it is an inert gas, is stored in our body in the same way as the invisible gas in a closed bottle of soft drink. Everything starts in the lungs, where the alveoli and capillary membranes distributed the nitrogen dissolved in the blood. This enriched in nitrogen blood transported by the arteries then spreads into different tissues of the human body. This is considered an absorption. In decompression models, these tissues are commonly called compartments. The longer we remain submerged, and deeper, more increases the level of nitrogen, until a tissue reaches its saturation point. In the course of one immersion, the tissues become saturated with different levels of nitrogen. This is determined by the level of tissue blood supply.
