The single-breath diffusing capacity test is the most common way to determine . The test is performed by having the subject blow out all of the air that they can, leaving only the residual lung volume of gas. The person then inhales a test gas mixture rapidly and completely, reaching the total lung capacity as nearly as possible. This test gas mixture contains a small amount of carbon monoxide (usually 0.3%) and a tracer gas that is freely distributed throughout the alveolar space … WebBruce H.
