  • Multiple breath washout cannot be used for tidal breath

    There are differences in tidal breathing parameters during MBW testing with SF6 in infants. It is, therefore, important to measure a separate tidal breathing trace in room air, prior to MBW testing to ensure rigour of tidal breath indices derived from analysis.Cited by: 6

  • Multiple breath washout (MBW) testing using sulfur

    Feb 16, 2021Abstract 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.
