Multiple breath washout (MBW) testing using sulfur

Background Multiple breath washout (MBW) using sulfur hexafluoride (sf 6) has the potential to reveal ventilation heterogeneity which is frequent in patients with obstructive lung disease and associated small airway dysfunction. However, reference data are scarce for this technique and mostly restricted to younger cohorts. We therefore set out to evaluate the influence of anthropometric
