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.

Diffusion Capacity in Heart Transplant Recipients

Chest, 1992
Preoperative diffusion capacity per liter alveolar volume (Kco) in cardiac transplant recipients with an intrinsic normal lung is within the normal range. In the first postoperative year, Kco showed a significant mean decrease of 12 percent (p less than 0.004). Lung function (TLC, VC, FEV1) tended to normalize after heart transplantation.

The Single-Breath Carbon Monoxide Diffusing Capacity

, 2015
Measurements of the single-breath carbon monoxide diffusing capacity (Dl) were obtained on a randomly selected sample representative of the white non-Mexican-American population of Tucson, Arizona. Methods of measurement followed the guidelines set forth

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 ...

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.

Diffusing capacity and forced vital capacity in 5,003 asbestos-exposed workers: relationships to interstitial fibrosis (ILO profusion score) and pleural thickening.

American Journal of Industrial Medicine, 2013
BACKGROUND Asbestosis is an interstitial lung disease whose radiographic severity has long been graded by the International Labour Office (ILO) profusion score. Its effect on pulmonary function is further impacted by asbestos related pleural thickening.

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.

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.

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 ...
