DLCO versus DLCO/VA as predictors of pulmonary gas exchange

WebFor the test, a gas called carbon monoxide (CO) is used, which is why the test is sometimes referred to as a DLCO. This stands for diffusion capacity through the lungs of carbon monoxide. 3 CO is used because, like oxygen, it has a high affinity for hemoglobin. Also like oxygen, it has the ability to pass through alveolar and capillary walls.
