Shunt mismatch

WebPhysiological dead space or physiological shunts, arise from a functional impairment of the lung or arteries. This happens when there is a lack of blood flow where the alveoli have enough air to oxygenate blood or there is a lack of air in an area where the blood flow is normal. A physiological shunt can develop if there is infection or edema ...
