WebThe result of DLCO test in patients with anemia change when we adjust DLCO for hemoglobin (Hb) concentration. The aim of the study was to estimate if the differences between result of DLCO and DLCO/VA before and after adjust the Hb value can change the interpretation of the test in the group with normal and low value of Hb. The study group ... WebAdjusted DLCO (DLCOc) = Predicted DLCO x ((1.7 x Hgb) / (9.38 + Hgb)) The adjustement of DLCO due to hemoglobin can sometimes be of essential importance given that slight …

WebJul 14, 2024 · COHb is known to affect DLCO measurement through occupation of hemoglobin binding sites and decreasing driving pressure of carbon monoxide transport from alveoli to blood, with a total effect of reducing measured DLCO . In the present study DLCO was not corrected for COHb, which may have biased the estimation of association … WebBackground: The diffusing capacity of the lung is usually reported as both the diffusing capacity (DLCO) and the diffusing capacity divided by the alveolar volume (DLCO/VA). … bapen 2019
