I just read the Scientific American article, one paragraph is: " Paradoxically, bubbles do not seem to form within the blood itself. Experiments first performed by...Erasmus...showed that when sealed in its natural container-a blood vessel-and isolated from the circulation, blood does not bubble even when severely decompressed. These observations were confirmed in our laboratory, where we could not detect bubbles in blood in an isolated vein even after we decompressed it from 122 atmospheres. Something in addition to supersaturation seems to be required for bubbles to form." This indicates to me that the bubbles are not coming from the blood. Of course, this does not mean that Doppler bubbles are not giving us useful information...
