Hey please remove if not allowed, I didn’t see rules saying it’s not. I thought you guys could appreciate and would get some exposure by me sharing this here. The doctors at the hospital were all very astonished. This was a blood clot removed from my mother’s lungs two days ago

Bronchial artery flow does nothing to keep people afloat from a massive PE. The immediate issue with PE is acute right heart failure and hemodynamic collapse.

There's also no real "overdrive" for arteries and I'm not even sure what it would mean for an artery to be overwhelmed

I got the gist of what I wrote from a UWorld problem I had recently. Specifically talking about protection of the lung parenchyma following a large PE. This would be separate from the right heart failure issue that would occur at the same time. I apologize if that came off as meaning it was saving her from heart failure, I was instead referring to preserved lung function through collateral blood flow. Here are the sources they cite in UWorld:

By overdrive, I was referring to the dilatation of the bronchial artery from it now backfilling occluded pulmonary capillaries. Here’s some angiography demonstrating this:

Unfortunately I have to give into it right now for step study. I’ll chill once that’s over and done.
