WebJul 18, 2024 · A low KCO can be due to decreased perfusion, a thickened alveolar-capillary membrane or an increased volume relative to the surface area. A high KCO can be due to increased perfusion, a thinner alveolar-capillary membrane or by a decreased volume relative to the surface area. WebThe DLCO depends not only on the area and thickness of the blood-gas barrier but also on the volume of blood in the pulmonary capillaries. The distribution of alveolar volume and …
