WebAug 31, 2015 · It has previously been reported that the amount of CO diffusion may be highly affected by changes in perfusion and blood hemoglobin concentration. 6,17 Changes in hemoglobin and circulation are seen in other systemic diseases. 31,32 Recent studies indicate that this is also the case in COPD. 33,34 As such, it is perhaps not surprising … 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
