What vascular anatomic alteration could occur as a consequence of hypoxia in your RDS patient?

Question

Quizplus · Accepted Answer

Hypoxia can cause vasoconstriction in the pulmonary blood vessels, leading to an increase in pulmonary vascular resistance and ultimately pulmonary hypertension. This is a common complication in neonates with respiratory distress syndrome. Closure of the ductus arteriosus increases pulmonary blood flow and is not a consequence of hypoxia. Increased flow through the ductus venosus is not related to hypoxia. Airway mucosal edema is a consequence of inflammation and is not directly related to hypoxia.
