Quizplus · Accepted Answer

Reduced diffusing capacity of the lungs (DLCO) is the most common pulmonary function abnormality found in patients with idiopathic pulmonary artery hypertension (IPAH). This is because the disease affects the pulmonary vasculature, leading to reduced blood flow to the lungs and impaired gas exchange, which is measured by DLCO. The other options listed are not typically affected in IPAH.
