WebAug 16, 2015 · Carbon monoxide (CO) has an affinity for hemoglobin approximately 220 times greater than oxygen and was the first gas used to measure diffusing capacity (DLCO). DLCO has been a routine test for well over 50 years and has been measured by single-breath, steady-state and rebreathing techniques. 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.
