Significats de diffuse capacity en anglès

All had severe reductions in diffusing capacity out of proportion to their lung volumes and spirometry.

Patients with this entity have relatively preserved lung volumes and spirometry but marked reductions in diffusing capacity on pulmonary function testing.

Diffusing capacity for carbon monoxide was low in only one case, and oxygen exchange during exercise was normal in six of nine subjects studied.

Subjects were interviewed for respiratory symptoms and occupational history, underwent plethysmographic measurements of lung volume and airflow, and performed a single breath diffusing capacity procedure.

Rationale: American Thoracic Society guidelines state that a 10% or greater intersession change in diffusing capacity of the lung (DL(CO)) should be considered clinically significant.
