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 Web31 Aug 2024 · Uneven distribution of ventilation-perfusion in the lungs can reduce DLCO. What’s the normal range for the DLCO test?

"Web18 Jul 2024 · Interstitial involvement in restrictive lung disease is often complicated and there can be multiple reasons for a decrease in DLCO. Scarring and a loss of elasticity causes the lung to become stiffer and harder to expand which decreases TLC. The alveolar membrane can thicken which increases the resistance to the transfer of gases. " - Things that decrease dlco
