Here you\u2019ll get the theoretical foundation for everything that later relates to no-decompression limits, dive profiles, and decompression strategies. Clearly explained, without an unnecessary barrage of formulas.         How inert gases enter the body and leave it again    Why different tissues saturate at different rates    What M-values and gradient factors mean in practice"}
