Liver and lung syndrome

Hepatopulmonary syndrome (HPS) is based on chronic liver disease and / or portal hypertension with abnormal dilation of pulmonary blood vessels, gas exchange disorders, hypoxemia due to abnormal arterial oxygenation, and a series of pathologies. Physiological changes and clinical manifestations. The clinical features are the triads after excluding primary cardiopulmonary disorders—basic liver disease, pulmonary vasodilation, and arterial blood oxygenation dysfunction. Abnormal arterial blood oxygenation caused by pulmonary gas exchange disorders—alveolar gas-arterial blood oxygen partial pressure difference rise, hypoxemia, is an important physiological basis of HPS. HPS is a serious pulmonary complication of end-stage liver disease, which is clinically manifested by dyspnea and cyanosis.
