Q

pulmonary embolism patho

A

occlusion of pulmonary arteries from a clot , decreased blood flow to alveoli allowing no gas exchange

-v/q mismatch prevents gas exchange

Q

PE can lead to….

A

increase pulmonary vascular resistance because blood flow cannot move past the clot

**lead to HTN –> back flow of blood to R ventricle –> R sided HF
