The intrapulmonary gas mixing (N(2)-slope) and diffusion capacity for carbon monoxide (D(LCO)) was evaluated and determination of cardiac output was

the volume of blood in the pulmonary capillaries available to bind carbon monoxide. The lower the volume, the lower the diffusion capacity. While interstitial lung diseases thicken the alveolar capillary-membrane, thickening of the membrane is not the major factor behind the observed reduction in diffusion capacity. This test is used to estimate the transfer of oxygen from the alveoli in your lungs to your bloodstream. The diffusing capacity (DL) of oxygen is technically very difficult to measure, and the test actually measures the diffusing capacity of carbon monoxide (DLCO) which provides a valid estimate of the oxygen diffusion. Lung diffusion capacity testing is a quick, noninvasive procedure that can help doctors estimate how well a person’s lungs are exchanging gases. They may use the test to diagnose conditions or to "The diffusing capacity is defined as the volume of gas that will diffuse through the membrane each minute for a partial pressure difference of 1mmHg." Nunn's defines it a little differently: " [Diffusing capacity is] the propensity of a gas to diffuse as a result of a given pressure gradient" DLCOor TLCO(diffusing capacityor transfer factor of the lungfor carbon monoxide(CO),) is the extent to which oxygen passes from the air sacsof the lungsinto the blood.

Pulmonary capacity is the sum of two or more primary lung volumes.

Study objective: Single-breath diffusing capacity of the lung for carbon monoxide (DLCO) is used as a pulmonary function test (PFT) to assess gas transfer in the lungs. The implications of a low DLCO are well-recognized, but the clinical significance of a high DLCO is not clear.

Higher values of pulmonary function have been reported in swimmers as compared to winter sport athletes and non-athlete controls (Bougault V. et al. Chest 2010; 138(2):31-7), and higher diffusion capacity (DLCO) in endurance athletes compared to age-matched controls (Degens H. et al.

It is completed after spirometry when an obstruction or lung volume issues are predetermined. Differentiating emphysema from obstructive bronchitis and chronic asthma; Assessment of COPD; Detection of pulmonary vascular disease 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.
