Pulmonary diffusing capacity after maximal exercise
Journal of Applied Physiology, 1993To determine the effect of maximal exercise on alveolocapillary membrane diffusing capacity (Dm), 12 professional handball players aged 23.4 +/- 3.3 (SD) yr were studied before and during early recovery from a progressive maximal exercise [immediately (t0), 15 min, and 30 min (t30) after exercise]. Lung capillary blood volume and Dm were determined in

Pulmonary Diffusing Capacity in Left Ventricular Dysfunction
Chest, 1990The purpose of this study was to determine whether there are any consistent spirometric or Dsb findings in patients with LV dysfunction characterized by a clinical diagnosis of CHF and an EF less than 40 percent. We performed spirometry and Dsb in 34 patients, and found that EF correlated only with Dsb.

Effect of uneven ventilation on pulmonary diffusing capacity
Journal of Applied Physiology, 1961In four normal subjects measurements of steady state diffusing capacity for CO (DLCO) by an alveolar sample technique and of the degree of uneven ventilation by nitrogen washout were made simultaneously followed by measurement of DLCO by rebreathing. A methacholine-histamine aerosol was then given.

Pulmonary Diffusing Capacity during Exercise in Women
Chest, 1973Steady state exercise diffusing capacities at three different levels of work have been measured in 46 women, aged 20 to 59. All the subjects had normal resting pulmonary function tests and normal chest radiographs. There was an age dependent decline in the exercise diffusing capacity of the lung at all work levels, which became more marked after the ...

Pulmonary diffusing capacity in the presence of ventilation inhomogeneity
Journal of Applied Physiology, 1987A model has been developed to quantify the effectiveness of alveolar-capillary transport in the presence of ventilation inhomogeneity. The exhalation dynamics of carbon monoxide (CO), argon (Ar), and lung volume from a single-breath experiment are analyzed simultaneously.

Gas chromatography in determination of pulmonary diffusing capacity
Journal of Applied Physiology, 1964Measurements of pulmonary diffusing capacity (Dco) were made using gas chromatography. The standard breath-holding technic was employed with the modification of using neon instead of helium for the dilution-reference gas. The two basic columns, silica gel, and 13 x molecular sieves were arranged in series on a dual-column chromatograph.

Pulmonary transit time and diffusing capacity in mammals
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1984Allometry is used as a tool to explain the apparent mismatch of oxygen consumption and diffusing capacity in the mammalian lung. By combining equations for pulmonary capillary volume and cardiac output, it is apparent that erythrocyte transit time through the lung must scale disproportionately to body mass. This inequality is a consequence of physical

Pulmonary Diffusing Capacity and Alveolar-Capillary Equilibration
1988In this short overview, theoretical and experimental work by the author and his co-workers pertaining to alveolar-capillary equilibration in mammalian lungs is summarized. The report is subdivided into four sections, each dealing with a different aspect of the topic: I. Diffusing capacity and diffusion/perfusion model. II.
