[The application of multiple breath nitrogen washout in chronic obstructive pulmonary disease].
We investigated ventilation inhomogeneity indices (Sacin, Scond) in patients with chronic obstructive pulmonary disease (COPD) using the multiple breath nitrogen washout test (MBNW) and determined the correlation between the 2 indices ( Scond and Sacin, as a measure of ventilation inhomogeneity in conductive and acinar zones of the lungs, respectively) and lung function to investigate the significance of assessing the COPD severity with ventilation inhomogeneity indices. ⋯ Sacin and Scond in COPD patients increased significantly, which was significantly correlated with lung function. COPD has ventilation inhomogeneity in conductive and acinar zones and ventilation inhomogeneity indices can be used to evaluate the severity of COPD.
