Deepmaxim,
Yes there will be all the gasses in the bubbles present but not much oxygen because oxygen never rises much over ambient pressure due to metabolic use. That is certainly true for venous blood which is inherently undersaturated. So there will always be a gradient there driving oxygen from inside bubbles out. The hemoglobin is critical because once it becomes unsaturated it will pickup excess oxygen from solution which will prevent bubbles from forming. But yes the rate of decay will be less for poorly perfused tissues like ligaments and tendons which is where you reported your pain. Still I suspect inert gas elimination drives DCS and the occurrence of symptoms after the gas switch to oxygen was a coincidence.
Thank you for reporting the details of your dive. What depths did you do the gas switches at? And why no “S” curve?
