Rah, iirc, actual oxygen absorption from the bubble rising is only around 5% of the O2 available in the bubble before it surfaces. Obviously, the smaller the bubble and the length of travel will make a big difference in that percentage...clouds of micro bubbles in the 1-2 micron size will rise very slowly and can approach 100% absorption where as an airstone like those used in aquariums, even the "very good" ones will produse a "course" larger bubble and even 1%absorption would be pretty good.
Atmospheric air contains mostly nitrogen and unless pure oxygen is being diffused with a diffuser DESIGNED for oxygen, the amount of qxygen being absorbed directly from the bubble is virtually meaningless to the change in how saturated water becomes with oxygen.
