Clinical Significance of Elevated Diffusing Capacity

Chest, 2004
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.

Placental diffusing capacity in unanesthetized rabbits

American Journal of Physiology-Legacy Content, 1975
The purpose of this study was to determine the placental diffusing capacity of CO in unanesthetized rabbits. A standard dose of CO was administered to 18 near-term rabbits, and at time intervals varying from 5 min to 4 h maternal and fetal blood samples were analyzed for carboxyhemoglobin saturation (HbCO). Following administration of CO, the maternal

Examination of the carbon monoxide diffusing capacity (DL(CO)) in relation to its KCO and VA components.

American Journal of Respiratory and Critical Care Medicine, 2012
The single-breath carbon monoxide diffusing capacity (DL(CO)) is the product of two measurements during breath holding at full inflation: (1) the rate constant for carbon monoxide uptake from alveolar gas (kco [minute(-1)]) and (2) the "accessible ...

Relative importance of diffusion and chemical reaction rates in determining rate of exchange of gases in the human lung, with special reference to true diffusing capacity of pulmonary membrane and volume of blood in the lung capillaries.

Journal of applied physiology, 1957
An equation, i/Dm + i/θVc = i/Dl, has been derived which relates the measured pulmonary diffusing capacity (Dl), the true diffusing capacity of the pulmonary membrane (Dm), the rate of uptake of CO...

The diffusing capacity in pulmonary emphysema.

The American review of respiratory disease, 1974
The results of measurements of pulmonary diffusing capacity (Dl), ratio of pulmonary diffusing capacity to alveolar volume (Dl/Va), and Krogh’s constant (k) were compared to the severity of postmor...

Physical Training and the Pulmonary Diffusing Capacity

Diseases of the Chest, 1969
The effects of nine weeks of physical training on certain ventilatory variables and the pulmonary diffusing capacity for carbon monoxide were studied in ten university distance runners. A nonexercising control group of five medical students was also investigated.

Diffusing Capacity in Healthy Elderly Chinese

Gerontology, 1989
Diffusing capacity (DLCO) was measured in 260 healthy subjects aged 60-86 years who were leading an active life in the community. DLCO correlated with body surface area and spirometric indices, and declined with age. It was lower in women, in smokers and in those with chronic bronchitis.

Lung Diffusion Capacity in Early Cirrhosis: Is Lung Diffusion Capacity a Predictor of Esophageal Varices and Ascites?

Digestive Diseases and Sciences, 2010
Varices and ascites are clinical manifestations of hyperdynamic circulation syndrome originating from increased nitric oxide in cirrhosis. Research was conducted in order to find any correlation between lung diffusion capacity and the presence of varices and ascites in cirrhosis.The study was conducted on a total of 120 subjects.
