DOI: 10.1152/japplphysiol.00129.2021
Abstract: INTRODUCTION Recent studies indicate limited utility of nitrogen multiple breath washout (N2MBW) in infancy and advocate for using sulphur hexafluoride (SF6)MBW in this age group. Modern N2MBW systems, such as EXHALYZER D® (ECO MEDICS AG,… read more here.

DOI: 10.1152/japplphysiol.00423.2022
Abstract: Sensor errors resulting in elevated values of N2 concentration [N2] in commercial multiple-breath washout (MBW) devices have been shown to prolong the washout and result in erroneously high FRC and LCI values. The errors also… read more here.

DOI: 10.1152/japplphysiol.00524.2017
Abstract: The detrimental effects on breathing pattern during multiple breath inert gas washout (MBW) have been described with different inhaled gases [100% oxygen (O2) and sulfur hexafluoride (SF6)] but detailed comparisons are lacking. N2- and SF6-based… read more here.

DOI: 10.1183/13993003.01832-2015
Abstract: Multiple breath washout (MBW) assesses both lung volume (functional residual capacity (FRC)) and ventilation inhomogeneity (lung clearance index (LCI)). The latter's insight into underlying lung pathology and response to intervention has triggered a recent MBW… read more here.

DOI: 10.1186/s12931-020-01575-x
Abstract: Background Despite demonstrated symptomatic benefit from bronchial thermoplasty (BT), the underlying pathophysiological benefits have been uncertain. The purpose of the present study was to relate clinical benefit after BT to changes in lung physiology, focusing… read more here.

DOI: 10.1186/s12938-018-0442-3
Abstract: BackgroundThe multiple-breath washout (MBW) is able to provide information about the distribution of ventilation-to-volume (v/V) ratios in the lungs. However, the classical, all-parallel model may return skewed results due to the mixing effect of a… read more here.
