Diffusing capacity for carbon monoxide

D_LCO or T_LCO (diffusing capacity or transfer factor of the lung for carbon monoxide (CO),^[1]) is the extent to which oxygen passes from the air sacs of the lungs into the blood. Commonly, it refers to the test used to determine this parameter. It was introduced in 1909.^[2]
