WebPulmonary diffusing capacity for oxygen increases progressively with increasing severity of exercise; it exceeds the Dl CO at high levels of exercise by amounts greater than can be accounted for by the difference in diffusivity of the test gases. Diffusing capacity for carbon monoxide increases less than Dl OO2 for comparable grades of exercise ... WebJan 19, 2024 · Some might say that the discussion of any resting diffusing capacity is a misnomer because it refers to an unstressed system, which in fact has a much higher capacity for diffusion. Indeed, with vigorous exercise, D LO2 increases from 20-30 ml/min/mmHg to something close to 100-120 ml/min/mmHg, which is the "real" capacity …

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. WebIn concert with alterations of the alveolar–capillary membrane, these lesions impair both gas diffusion and ventilation/perfusion (V′/Q′) relationships in the lung, leading to reduced diffusing capacity of the lung, increased dead space ventilation, and increases in the alveolar–arterial oxygen tension difference (P A–aO 2) and ...
