Your input: Graph of dive depth over time Values for Rate of Absorption of No2 for the 2 tissue types Siderbar for the N O Mix in the Tank The basic idea is this: At depths below 33 feet divers build up nitrogen in their bodies. Too much nitrogen in body tissue gives them the bends, which can be fatal. To avoid this, divers going deep follow a dive table which tells them when to pause in their ascent to let the nitrogen disperse. Different types of body tissue absorb nitrogen at different rates. Navy dive info uses 5 or 6 different body tissue types; this model uses 2 -- Type 1 is slow to absorbe/release and type 2 is quick to absorb release nitrogen. Typical values for the absorption rates are 0.1 and 0.5. You can control the N - O mix in the air tank and -- more importantly -- the dive depth schedule. You can also change the absorption rates for the 2 types of body tissue. -+ &N$D9  A'()*4If% n& n 506Stop-+ drmd8plwh0 2 '   h+& s8_@o{B.p>K'()*+ & d9@^x0B"'()*+ & b:s@B&PlpEQY':#:I()'IEIm*+ & a wV@^P<zZ'()*+ & cQ@Dro'()*+ & a/W$@l=X'()*+ & cub@h= '()*+ & aYi#@lDfq'()*+ & cdE5@  W7S '()*+ & c@   '()*+ & a {@M hI'()*+ & cc@ > '()*+ & a Wy@lP t\'()*+ & a" p@l \'()*+ & sQ@vd to0r'()*+ & d!@l*'()*+ & b@ llp#C'+;()'wXwi*+ & c' @o[24;63{E'()*+ & a!@nF*'()*+ & anN@nHIP'()*+ & a 2G@nIGa'()*+ & alh n\@nJ@>'()*+ & a &r6@nJ'()*+ & c7 @$J'()*+ & an X@F@'()*+ &NuDu m'()*4 5XA5Tn& n 50%" 6Return to Simulation Level-+ drmd8plwh0 *66_<G 8'L0L(F50%5@ 9``585(5$@r@r*Concentrations:;D@Hp@-;@Hp@-; @Hp@-" <= N~M L44B4IA  44 & )    drmd N > 44 & >0    drmd ~  4B &  7    drmd  44B &?;@T AbbBBEPBABF L(BCDDDD E F-" F-" F- " F- "  Gv2HIJGenevaJGenevaGK L /L/,M QV\.*
