WebA correction factor to calculate the true DLCO in patients with healthy lungs but with anemia is specified. In the patients with interstitial pulmonary fibrosis, the influence of the reduced diffusing capacity of the alveolocapillary membrane on the extent of the diffusion disorder was in each case greater than the effects due to the anemia. WebDiffusing capacity for carbon monoxide. DLCO or TLCO ( d iffusing capacity or t ransfer factor of the l ung for carbon monoxide (CO), [1]) is the extent to which oxygen passes from the air sacs of the lungs into the blood. Commonly, it refers to the test used to determine this parameter. It was introduced in 1909. movie the junction boysWebDLCO Hgb is a large part of these algorithms. There are two equations used to correct DLCO for hemoglobin (Hgb), the Dinakara[6] and Cotes[7] equations.
