WebDiffusing Capacity. The diffusing capacity is a measurement of the rate of transfer of gas from the alveolus to hemoglobin within a capillary, measured in relation to the driving pressure of the gas across the alveolar-capillary membrane. Small concentrations of carbon monoxide are generally used for this purpose.
