WebSep 8, 2024 · However, one commonality which is valid across all ARDS patients is the presence of intrapulmonary shunting. Shunting results from alveolar units which receive blood flow but no ventilation, causing a shunting of deoxygenated blood into the systemic circulation. Shunt physiology causes cardiac output to affect the oxygen saturation, … A pulmonary shunt often occurs when the alveoli fill with fluid, causing parts of the lung to be unventilated although they are still perfused.
