Cooldiver,
Let us say you have a spectrum. At one end you have 0 nitrogen and at the other you have nitrogen saturation. Put two divers at a depth of 20m, have all other variables the same, except breathing rate. Do you not think the one that takes more breaths will reach saturation quicker? Because the volume of air breathed will affect the volume of nitrogen absorbed? Not trying to prove you wrong, just checking if I'm correct.

I have a question unrelated to the topic but still on nitrogen absorption. Why on the PADI tables does it recommend you add 4m when calculating dives in cold water? I am against the cold more then I'm against mugabe so haven't dived in anything less then 23oc. I cannot see how cold water can directly increase your absorption rate. Does it affect your breathing, or am i wrong and it affects your body tissues ability to absorb nitrogen? Does it have to do with strain. OK ......Andrew why exactly 4 mtrs cant tell you in a short way. We would have to sit and discuss Buhlmann tables and so on, If you are interested go look at some technical dive course offered by NAUI, TDI, IANTD. Why they say you should calculate deeper for cold dives is because; to keep your core temperature constant you need to burn energy, this increases the bodies metabolism, doing so you on gas a lot faster. Meaning that your absorbtion rate is higher in a shorter time. Meaning that if you did not plan a depth of 4 mtrs extra the possibility of "bends" or "embolism" increases............... Hope this answers your question.

not exactly the same difference. Thanks for the info though, it makes sence, what about the other topic, do you think breathing rate affects absorbtion rate
