Diffusing capacity, membrane diffusing capacity, capillary blood volume, pulmonary tissue volume, and cardiac output measured by a rebreathing technique.

American Review of Respiratory Disease, 2015
A rebreathing method for estimating diffusing capacity, membrane diffusing capacity, pulmonary capillary blood volume, pulmonary capillary blood flow, and pulmonary tissue volume consists of rebreathing into a bag for 15 sec while acetylene, (18O)-carbon

Pulmonary Diffusion Capacity

1991
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.

Diffusing capacity of the lung in pulmonary emphysema

Journal of Applied Physiology, 1964
Steady-state CO and O2 methods for measuring pulmonary diffusing capacity may be affected by abnormal distribution of inspired gas relative to perfusion. These methods frequently fail to separate abnormalities in diffusion from abnormalities in distribution in patients with obstructive emphysema.

Effect of lung volume on steady state pulmonary membrane diffusing capacity and pulmonary capillary blood volume.

American Review of Respiratory Disease, 2015
Although resting steady state measurements of pulmonary diffusing capacity of the lung are frequently used in the evaluation of patients, results from such tests are often quite variable because the steady state method is highly dependent upon alveolar ...

Pulmonary Diffusing Capacity On Exercise

, 2016
Thank you very much for reading pulmonary diffusing capacity on exercise. As you may know, people have look numerous times for their favorite novels like this pulmonary diffusing capacity on exercise, but end up in infectious downloads.

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.

The effect of tiotropium on the pulmonary diffusing capacity

Methods and Findings in Experimental and Clinical Pharmacology, 2007
To 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.

Morphometric model for pulmonary diffusing capacity I. Membrane diffusing capacity

Respiration Physiology, 1993
The pulmonary diffusing capacity is related to the quantitative design characteristics of the pulmonary gas exchanger. The current model for estimating DLO2 from morphometric data breaks the diffusion path for O2 into four steps, three of which represent the membrane part of DLO2.

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...

INCREASE OF PULMONARY DIFFUSING CAPACITY IN SYSTEMIC SCLEROSIS

Rheumatology, 1994
Pulmonary function tests and chest radiographs of 29 non-smoking systemic sclerosis (SSc) patients were analysed, featuring an apparently paradoxic finding of an increased diffusing lung capacity for carbon monoxide (DLCO). Twenty-one patients (72%) had abnormal pulmonary function, 11 of them had restrictive disease (38%), six (21%) had isolated DLCO ...
