This is not so.  There is little (or no?, comments Prime Ra?) evidence that 
bubbles trap in the arterial circulation.  One workers calculations suggest 
that the bubble, which would be tubular in shape, would need to extend 
through three generations of arteries before they would trap.

Bubbles are a problem if untrapped, they activate the  complement and kinin 
systems and damage the blood vessel endothelium.
