The Role of Diffusing Capacity and Exercise Tests

Thoracic Surgery Clinics, 2008
Beside pulmonary function tests, other measures of cardiopulmonary fitness have been shown to be useful for preoperative risk stratification. Reduced values of carbon monoxide lung diffusion capacity and its predicted postoperative value have been reported to be associated with postoperative complications and mortality.

Physical training and exercise diffusing capacity

Internationale Zeitschrift f�r Angewandte Physiologie Einschlie�lich Arbeitsphysiologie, 1968
The diffusing capacity (D L,CO) has been measured repeatedly by an improved “brief steady-state” technique in a total of 13 experimental and 4 control subjects. Both resting and exercise (D L,CO) were initially somewhat higher in the more athletic subjects.

Measurement of diffusing capacity in pulmonary embolism

Respiratory Medicine, 1989
Pulmonary 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 ...

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

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.
