WebInterpretation of pulmonary function tests is important and is addressed in CHEST (October 2024) by Neder et al.1 However, their description of lung diffusing capacity interpretation is convoluted. A much simpler, intuitive interpretation of diffusing capacity is based on the effect of lung volume on the diffusing capacity of the lung for carbon monoxide (Dlco) … WebA low DLco (corrected for hemoglobin) and DLco with alveolar volume (VA) correction (ie, DLco/VA) were defined as values of less than 80% predicted. All patients underwent three high-resolution computed tomography (HRCT) scans of the chest, using a low-dose, non-contrasted protocol that included both inspiratory and expiratory scans.
