The mechanism to deflate them -- metabolic use of oxygen -- does away with
oxygen bubbles few minutes after your return to normoxia. You may be right
in assuming that oxygen bubbles persist as long as they're bathed in oxygen
enriched plasma. However, if an oxygen bubble ever blocks local circulation,
local demand (downstream of the block) will start eating it away. 

Bubbles are a non-issue until they get stuck -- at that point oxygen bubbles
create the scenario for their own elimination.

Hans
