DLCO is decreased in any condition which affects the effective alveolar surface area: 1. Hindrance in the alveolar wall. e.g. fibrosis, alveolitis, vasculitis 2. Decrease of total lung area, e.g. Restrictive lung disease or lung resection (partial or total). 3. Chronic obstructive pulmonary disease (Emphysema) due to decreased surface area in the alveoli, as well as damage to the capillary bed WebDLCO may be measured using either a single-breath or a steady-state technique. DLCO is decreased in interstitial lung disease (e.g., idiopathic pulmonary fibrosis, sarcoidosis, systemic sclerosis), conditions that decrease the surface area for diffusion (emphysema, tumors, low cardiac output states), and in states of V./Q. mismatch.
