Diffusing capacity measures the features at work involving movement of oxygen from the alveolar surface through to the hemoglobin molecule. The clinical test that determines diffusing capacity of the lung most commonly uses carbon monoxide (CO) as the tracer gas for measurement because of its high affinity for binding to the hemoglobin molecule.

Measuring diffusion provides information on gas transfer between the alveoli and the blood of the pulmonary capillaries and we generally refer to it as diffusion capacity (DLCO). 1,2 To assess the functional integrity of the diffusion process a gas must be used that is not present in venous blood, that has an affinity for haemoglobin and that is soluble in blood.

In patients whose DLCO is low, the use of a VA derived from dilution may result in a "normal" DLcoNA. In such cases, I calculate DLcoNA using the total From Wikipedia, the free encyclopedia DLCO or TLCO (d iffusing capacity or t ransfer factor of the l ung for carbon monoxide (CO),) 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.

Jan 11, 2017 Normal ventilation of alveoli results in a large reservoir of oxygen with a pressure of ∼100 mm Hg to promote diffusive transfer across the alveolar 

These normal values will come from one of several different population studies and there are two different ways of making this comparison. The apparent decline in DLCO with age (which is based solely on the equations and not on any longitudinal studies and is independent of height) ranges from 0.117 to 0.246 ml/min/mmHg per year for Caucasian males and 0.068 to 0.179 ml/min/mmHg per year for Caucasian females. Lung diffusion capacity is a simple, painless test to determine how well oxygen moves or diffuses into your bloodstream from your lungs. Doctors use lung diffusion capacity to diagnose and monitor conditions that affect the lungs’ ability to transfer oxygen into the bloodstream. Monoxide Diffusing Capacity," Plummer- correctly pointed out that lung diffusion capacity corrected for alveolar ventilation (Kco [or ratio of diffusing capacity of the lung for carbon monoxide (DLCO) to alveolar volume (VA)])is notconstant as VA changes. In fact, DLCO and Kco change with VA, as would Normal results of this test are set to a standard for lung function based on your age, sex, and height. it is just shorthand for diffusing capacity of the lungs A test of the diffusing capacity of the lungs for carbon monoxide (DLCO, also known as transfer factor for carbon monoxide or TLCO), is one of the most clinically valuable tests of lung function.
