        Interpretation of diffusing capacity values

        DLCO ≥80% and ≥LLNDLCO is normal
        DLCO <80% but ≥LLNDLCO is near lower limit of normal
        DLCO ≥60%, <80%, and <LLNDLCO is mildly reduced
        DLCO ≥40%, <60%, and <LLNDLCO is moderately reduced
        DLCO <40%DLCO is severely reduced
