WebSingle-breath diffusing capacity of the lung for carbon monoxide (Dlco) is used as a pulmonary function test (PFT) to assess gas transfer in the lungs. The implications of a low Dlco are well-recognized, but the clinical significance of a high Dlco is not clear. The aim of this study was to identify the clinical correlates of a high Dlco.

WebWe concluded that many functional parameters were useful in distinguishing the asthma and COPD groups. In individual analysis, DLCO was the parameter which best aided in an accurate diagnosis in both groups, with a higher specificity for COPD. The bronchodilator response measured by changes in FEV1 showed a higher sensitivity for asthma.
Web17 de ago. de 2024 · Overview. Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing.

In asthma, there is no destruction of the aveolar membranes so DLCO is normal.
