What does moderate to severe reduction in diffusion capacity at 48 mean?

Answer 1

A moderate to severe reduction in diffusion capacity at 48 refers to a significant impairment in the lungs' ability to transfer oxygen from the alveoli into the bloodstream, typically measured by a pulmonary function test called the diffusing capacity of the lungs for carbon monoxide (DLCO). This reduction can indicate underlying lung conditions such as pulmonary fibrosis, emphysema, or pulmonary hypertension. It suggests that the lungs are less efficient in gas exchange, which may lead to symptoms like shortness of breath and decreased exercise tolerance. Further evaluation and management by a healthcare professional are usually warranted in such cases.
