Clinical Significance of Elevated Diffusing Capacity
Chest, 2004Single-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.

Diffusion and Pulmonary Diffusion Capacity
Abstract One of the major roles of the lungs is to facilitate gas exchange from the circulatory system and the external environment. Gas exchange occurs in the lungs between alveolar air and blood of the pulmonary capillaries. A test of the diffusing capacity of the lungs for carbon monoxide (DLCO, also known as transfer factor for ...Anna Moldysz, Archit Sharma

The transport of the respiratory gases O2 and CO2 between ambient medium “air” and the internal medium “blood” is ensured by three basic mechanisms: ventilation, diffusion and perfusion.

Placental diffusing capacity in unanesthetized rabbits
American Journal of Physiology-Legacy Content, 1975The 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

Measurement of diffusing capacity in pulmonary embolism
Respiratory Medicine, 1989Pulmonary function tests were carried out in 20 consecutive patients with pulmonary embolism (PE), diagnosed on the basis of a positive ventilation-perfusion lung scan carried out within 72 h of admission. Changes in forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and arterial blood gas tensions were too variable to be ...

Capacity Building and IT Diffusion
Social Science Computer Review, 2007The “digital divide” in the utilization of e-government between the industrialized and developing countries stands to spell serious consequences for the latter's political and economic development. Because African countries rank very low on the global measure of e-government readiness, critical variables were studied to find out which policy and ...

The effect of tiotropium on the pulmonary diffusing capacity
Methods and Findings in Experimental and Clinical Pharmacology, 2007To our knowledge, there is no data on the effect of tiotropium on pulmonary gas exchange in healthy subjects. The aim of this study was to assess the effects of tiotropium on pulmonary diffusing capacity. Twenty-one healthy volunteers were enrolled for a prospective, randomized, double-blind, placebo-controlled study.
