what is a major complication in pts with COPD
In most capillary beds of the body, decreased oxygen leads to vasodilation in order to facilitate more bloodflow to the area to maintain perfusion, but the lungs are the one exception in which decreased oxygen leads to constriction of blood vessels feeding that area so that blood is preferentially sent to well-oxygenated portions of the lung to minimize V/Q mismatch, but can lead to cor pulmonale in patients with COPD because their entire lungs are poorly oxygenated, leading to diffuse vasoconstriction and increased afterload on right ventricle
