block-incr pul a pressure--->vasospam---->rel of TXA2/ 5HT
''----> ischemia of parencyma----->incr supply------>incr pul a pressure----->decr CO-----> R heart failure (cor pulmonale)----> therefore decr BP

There is ventilation perfusion mismatch, hypoxia, vasoconstriction, pulm ht, rhf, low co?

simply it make the pul system a hi resistance systme that u hardly can push any blood to the heart trough it (cor-pulmonale) dec preload can cause the hypotension
