Shunting of blood in lungs
WebWhat causes blood shunting? In shunting, venous blood enters the bloodstream without passing through functioning lung tissue. Shunting of blood may result from abnormal vascular (blood vessel) communications or from blood flowing through unventilated portions of the lung (e.g., alveoli filled with fluid or inflammatory material). WebThis results in a blockage of flow to the lungs with shunting of poorly oxygenated blood into the left ventricle and the systemic circulation. The other components of tetralogy of Fallot …
