Yes, it is possible to get decompression sickness with other gasses, such as the "oxygen bends" or oxygen decompression. For instance, in this study, they demonstrated that oxygen decompression sickness in mice. Another study demonstrates a more common non-nitrogen decompression sickness - helium bends. Undoubtedly you will be wondering at this ...

Summary The redox potential widely quoted in text books for the half-reaction reduction of FAD to FADH2 is indeed inconsistent with the observed direction of several reactions involving this coenzyme, including its reduction of NAD+ in the dihydrolipoamide dehydrogenase reaction. The reason for this is that the value quoted is determined for free FAD in ...
