Transfer of oxygen and carbon dioxide over the alveolocapillary membrane is the main function of the lungs and can be measured by the diffusing capacity for carbon monoxide (CO). CO has a high affinity for hemoglobin and is absent in pulmonary capillary blood.

Pulmonary diffusing capacity of athletes
Journal of Applied Physiology, 1963Champion swimmers have been found to have significantly higher steady-state pulmonary diffusing capacities than those measured in normal subjects of comparable age at the same exercise level. Nonactive and moderately active normal subjects, swimmers of average ability, long distance runners, and older ex-athletes were found to show no significant ...

Diffusion Capacity in Heart Transplant Recipients
Chest, 1992Preoperative 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.

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

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.

Physical training and exercise diffusing capacity
Internationale Zeitschrift f�r Angewandte Physiologie Einschlie�lich Arbeitsphysiologie, 1968The 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.

SINGLE-BREATH CARBON MONOXIDE DIFFUSING CAPACITY
Clinics in Chest Medicine, 2001Measurement of DL(CO) remains a clinically useful way to assess transfer of gases across the lung. It is important, however, to be vigilant in controlling the sources of variation and to be aware of those that remain when interpreting the measured values.

Diffusing Capacity Decreases After Heart Transplantation
Chest, 1993We evaluated the following spirometric values: forced vital capacity (FVC), first second expiratory volume (FEV1), FEV1/FVC, the lung volumes, total lung capacity (TLC), residual volume (RV), and single breath diffusing capacity for CO in 22 patients, before and after heart transplant.

Clinical Significance of Elevated Diffusing Capacity
Chest, 2004Single-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.
