ResumoIntroduction Multiple-breath nitrogen washout is an established and sensitive technique to assess functional residual capacity and ventilation inhomogeneity in the lung. Indirect calculation of nitrogen concentration requires precise calibration and accurate measurement of gas concentrations. We investigated the accuracy of the carbon dioxide gas concentration used for the indirect calculation of nitrogen concentration in a commercial multiple-breath washout (MBW) device (EasyOne Pro LAB, ndd Medizintechnik AG, Switzerland) as a possible cause of lack of comparability between outcomes of different MBW devices.
