Hmm. That are two orders of magnitude for the radius which translates to six
orders of magnitude for the volume. I would call that quite a range of values.
IF we take only one radius as initial value, which one would you suggest to
represent this range?

I doubt that. It is clearly unphysical to assume that there are bubbles that
contain only He and other only N2. In reality any bubble will contain a mixture
of all gases. Furthermore, oxygen plays no role in decompression calculations
due to its special role in the body where it is almost entirely bound to
haemoglobin rather than being dissolved in blood.
What about yesterday’s questions regarding the time evolution of the bubble
size?
