Final answer:
Oxygenation is improved in patients with hepatopulmonary syndrome when a liver transplant is performed. It is worsened when there is progression of the liver disease.
Step-by-step explanation:
Oxygenation is improved in patients with hepatopulmonary syndrome when a liver transplant is performed. Hepatopulmonary syndrome is a disorder that affects the lungs in patients with liver disease. It causes a decrease in arterial oxygenation due to the dilation of blood vessels in the lungs. A liver transplant can help improve the oxygenation levels by addressing the underlying liver disease and reducing the dilation of blood vessels.
Oxygenation is worsened in patients with hepatopulmonary syndrome when there is progression of the liver disease. As the liver disease progresses, it can lead to further damage and dysfunction of the liver, which in turn affects the lungs. The dilation of blood vessels in the lungs worsens, resulting in a further decrease in arterial oxygenation.
