WebDLCO may be measured using either a single-breath or a steady-state technique. DLCO is decreased in interstitial lung disease (e.g., idiopathic pulmonary fibrosis, sarcoidosis, systemic sclerosis), conditions that decrease the surface area for diffusion (emphysema, tumors, low cardiac output states), and in states of V./Q. mismatch. WebFor a measured DLCO of 15 ml CO/min/mm Hg and [Hb] ranging from 7 to 12 g/dl, the present DLCO adjustment is higher (by 2.7 ml CO/min/mm Hg, on average) than that proposed by Cotes and coworkers.
