Decreased lung diffusion capacity

WebSince diffusion of CO only happens in areas of the lungs where there are both ventilation and perfusion, if perfusion is diminished in an area it can decrease the global value of DLCO. This can be the case with pulmonary emboli or pulmonary hypertension. WebWhen the diffusing capacity test starts you will be told to breathe quietly for several breaths and then to blow out as much air as you can. When you have emptied your lungs you will be asked to take a quick deep breath in, as deep as you can, and then to hold it for 10 seconds. The inhaled gas contains a very low concentration of carbon monoxide.

Lung Diffusion Capacity Test: Why It

There are several conditions that may result in low diffusing capacity. Restrictive lung diseases such as pulmonary fibrosis most often decrease diffusing capacity (DLCO) because of scarring and thickening of the area between the alveoli and capillaries.
