  • SO2 Measurement in SF6 - MBW Calibration AG

    40 secs readSO 2 Measurement in SF 6 Sulphur Dioxide is the most common decomposition by-product measured during SF 6 gas quality analysis. Unlike most other decomposition products, it is relatively unreactive once formed, so its concentration remains stable over time, so measurement results are more dependable as a condition assessment parameter.

  • Difference between SF 6 and N 2 Multiple Breath Washout

    Background: Measurement of Lung Clearance Index (LCI) by Multiple Breath Washout (MBW) is a sensitive method for monitoring of lung disease in Cystic Fibrosis (CF). To compare N 2 MBW and SF 6 MBW, we connected these two gas analysis systems in series to obtain truly simultaneous measurements, with no differences other than the gas used.

  • Multiple breath washout (MBW) testing using sulfur

    Feb 15, 2021For both tracer gases, several adaptions to the measurement protocols have been proposed, including reduction of total measurements or earlier cut-offs for terminating the washout.44–47 Moreover, closed-circuit SF 6-MBW was shown to effectively reduce wash-in times.15 We therefore calculated reference values for an earlier 5% stopping point reducing washout times

  • Comparison of a new nitrogen multiple breath washout

    Background:The lung clearance index (LCI) obtained from SF6 multiple breath washout (MBW) is a sensitive index of peripheral airway dysfunction in cystic fibrosis (CF) [1]. SF6 LCI values are lower and show stronger agreement between laboratories than historical N2 LCI using conventional N2 analyzers [1]. Formal comparison between the two types of MBW systems has not been performed to date.

  • Multiple breath washout cannot be used for tidal breath

    Background: Multiple breath washout (MBW) testing with SF6 gas mixture is routinely used to assess ventilation distribution in infants. It is currently unknown whether SF6 changes tidal breathing parameters during MBW in infants. We investigated if SF6 does change tidal breathing parameters in infants and whether a separate tidal breathing trace prior to MBW testing is necessary.

  • Consensus statement for inert gas washout measurement

    Inert gas washout tests, performed using the single- or multiple-breath washout technique, were first described over 60 years ago. As measures of ventilation distribution inhomogeneity, they offer complementary information to standard lung function tests, such as spirometry, as well as improved feasibility across wider age ranges and improved sensitivity in the detection of early lung damage.
