Sure the problem is with my English :-P

This is not a only-lungs issue. The interface at alveoli level depends on gradient and surface of lungs tissue. The main thing is "transport" from/to the tissues.

The gas travels by your blood during ongassing and during offgassing. As much as your blood has empty spaces for transport as much as your deco will be more efficient. These spaces can be filled with N2, He or CO2 (that solves easily). Transport also depends on what big is your *map* of arteries and veins and this map is bigger as you have more "roads" for perfund your tissues.

The difference between parcial pressure of innert gas in the arterial system and the pp of i.g. in the venous system is called OW. The question is: "which way a diver can increase this difference (and increase the number of "roads" for gas)?" And the answer: with fitness (providing a good vascularity)

In the other hand, increasing the VO2max with training would provide a more effective gas interchange. Would you please search for "VO2max" in Google?

Cheers,
IB
