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.

Lung diffusing capacity and red blood cell volume

Respiration Physiology, 1991
The aim of this study was to test whether a large surface to volume ratio of the red blood cells is advantageous for O2 transfer in lungs. Suspensions of washed large (human) and small (sheep) red blood cells were used to perfuse in random order isolated cat lungs (n = 7). The lungs were kept at 27 degrees C, ventilated with 1.0 l/min and perfused with

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.

Reduced lung diffusion capacity after Mycoplasma pneumoniae pneumonia

The Pediatric Infectious Disease Journal, 2000
Mycoplasma pneumoniae is a frequent but underdiagnosed cause of community-acquired pneumonia (CAP) in children, and appropriate macrolide treatment is often given late. The aim of this work was to estimate the frequency of pulmonary involvement in children 6 months after a clinical episode of Mycoplasma CAP.We measured carbon monoxide diffusion ...

Factors Influencing the Diffusing Capacity of Each Lung

Respiration, 1972
18 patients with pulmonary tuberculosis and ventilatory insufficiency had a differential spirometry with determination of the following parameters in each lung: oxygen uptake, ventilation, vital ...

Characteristics of adjustment of lung diffusing capacity to work

Journal of Applied Physiology, 1982
The response of lung diffusing capacity for CO (DLCO) to the onset of exercise or a change in work load was studied in four healthy males. Single-breath DLCO was measured during the transients 1) from rest to 40% of maximum O2 uptake (VO2 max); 2) from rest to 80% VO2 max; and 3) from steady-state exercise at 40 to 80% VO2 max.

The lung of shrews: Morphometric estimation of diffusion capacity

Respiration Physiology, 1980
The lungs of 16 shrews from 8 species (Sorex minutus, Neomys fodiens, Suncus etruscus, Crocidura russula, C. juvenetae, C. poensis, C. flavescens, C. giffardi) ranging in body weight from 2.2 to 100 g were studied by morphometry in order to compare the structural diffusion capacity for oxygen.

Mechanisms behind inter-individual differences in lung diffusing capacity

European Journal of Applied Physiology, 2007
We measured diffusing capacity (DLCO), alveolar membrane properties (D (m)), capillary lung volume (V (c)), and alveolar volume (V (A) ) in 20 healthy subjects (12 males; age 32.4 +/- 13 (SD); BMI 21.7 +/- 3; non smokers) at total lung capacity (TLC) and at approximately 80, 60, and 40% TLC.

Lung membrane diffusing capacity, heart failure, and heart transplantation

The American Journal of Cardiology, 1999
The pulmonary diffusing capacity for carbon monoxide (DLCO) is reduced in chronic heart failure and remains decreased after heart transplantation. This decrease in DLCO may depend on a permanent alteration after transplantation of one or the other of its components: diffusion of the alveolar capillary membrane or the pulmonary capillary blood volume ...

Impairment of lung diffusion capacity in Schönlein-Henoch purpura

The Journal of Pediatrics, 1992
Twenty-nine children with typical Schönlein-Henoch purpura (SHP) were tested at the initial phase of the disease for respiratory function. Of the 29 patients, 28 had a decrease of lung transfer for carbon monoxide (TLCO) as measured by a steady-state method.
