Talk:Hyperbaric oxygen therapy

Can somebody please explain which therapeutic mechanism is at work in air/gas embolism? It seems quite plausible that it is the overall pressure which would serve to minimize the volume of any given amount of gas, but I don't have any references for that. Comments, please?

Indeed the pressure causes a decrease in the volume and therefor surface area of the bubble. The bubble acts to stop blood flow in the vessel in which it is impacted. Decreasing the surface area causes the bubble to migrate peripherally and thus impact smaller vessels. The bubble is comprised of 79% nitrogen. Using 100% oxygen causes a nitrogen gradient which causes the bubble to dissolve over time.
