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: 10.1186/s12890-017-0543-y
Abstract: BackgroundMultiple breath washout (MBW) became a valuable research tool assessing ventilation heterogeneity. However, routine clinical application still faces several challenges. Deriving MBW parameters from three technically acceptable measurements according to current recommendations prolongs test times.… 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.
