SUMMARY

1. Carbon monoxide diffusing capacity (DLCO) is decreased by anything that interrupts gas-blood O2 exchange (imapired O2 exchange).
2. It implies a loss of affective alveolar-capillary interface.
3. Decreased DLCO: emphysema, ILD, pulmonary vascular diseases, anaemia.

4. Normal DLCO: asthma and chronic bronchitis, where there is no alveolar disease.

5. Increased DLCO: heart failure, diffuse alveolar hemorrhage, pulmonary infarction, and idiopathic pulmonary hemosiderosis (IPH), where there is increased blood flow to functional lungs.

6. Monitor in ILD to assess progress. Helps distinguish b/w emphysematous COPD (low DLCO) from chronic bronchitis & asthma (normal DLCO).
