In addition, the capillaries in the lungs are thought to trap and filter out microbubbles from the blood.
A further danger is therefore that microbubbles trapped in the lung capillaries may be compressed by a subsequent descent to allow them to pass through the lungs to the heart to be pumped into the arterial circulation direct to the tissues, particularly the brain, possibly clumping together on the way.

Microbubbles form on all ascents.
All bubbles (although "trap" isn't a word I've seen used, in this respect before).
Any cessation of blood flow causes damage to all the blood starved areas "down current". I sincerely hope you do not suffer from blocked pulmonary blood vessels - of any size - post dive.
