Nevertheless, some technical limitations remain that hamper its widespread use. While most of the MBW data in infants have been acquired via sulfur hexafluoride washout (SF6–MBW), the nitrogen variant (N2–MBW) is recommended by the European Cystic Fibrosis Society Clinical Trial Network (ECFS–CTN) for older children.

  • 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.

  • Simultaneous sulfur hexafluoride and nitrogen

    12 mins readOct 01, 2019LCI is derived from the multiple-breath washout (MBW) test and is calculated by dividing the cumulative expiratory volume over the washout test, by functional residual capacity (FRC). MBW can be performed either with a tracer gas such as sulfur hexafluoride (SF 6), or can use 100% oxygen to wash out resident nitrogen (N 2).Cited by: 5

  • The effect of inert gas choice on multiple breath washout

    Dec 01, 2017Based on these results, SF6 based MBW is the preferred methodology for tests in this age range. NEW NOTEWORTHY Inert gas choice for multiple breath inert gas washout (MBW) in infants has important consequences on both breathing pattern during test performance and the functional residual capacity and lung clearance index values obtained.

  • SF6 Gas Measurement Theory - MBW Calibration AG

    Sulphur hexafluoride, SF 6, is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers as well as in high-voltage cables, transformers, and switchgears.

    We hypothesized that MBW measurements were attainable in infants with bronchiolitis and that LCI was raised and eNO reduced, compared to normal controls. Methods: Infants with acute bronchiolitis were tested with sulfur hexafluoride (SF 6) MBW during hospitalization and compared to controls. Tidal breathing and eNO parameters were obtained.

  • Using the same cut-off for sulfur hexafluoride and

    Recent evidence suggests that results from multiple-breath washout (MBW) using nitrogen (N2) as washout gas are different to those obtained by using sulfur hexafluoride (SF6). Explanations were mainly related to different MBW equipment and gas properties. We aim to mention a new aspect, namely using the same cut-off in both techniques to determine lung clearance index (usually 2.5% of initial

    TO THE EDITOR: Multiple-breath washout (MBW) is commonly used in the diagnosis and monitoring of cystic fibrosis (CF) lung disease and other lung diseases (4, 5). Nitrogen (N 2) and sulfur hexafluoride (SF 6) are tracer gases frequently utilized in MBW and the same 2.5% cut-off concentration point is used for both gases (5).

  • Multiple-Breath Washout as a Lung Function Test in Cystic

    In any washout test, there is a wash-in and a washout phase. For inert extrinsic gases (i.e., sulfur hexafluoride, SF 6; helium, He) or nonresident pulmonary gases, during the wash-in phase the test gas is delivered at a known concentration. Wash-in is complete when the expired gas concentration reaches the delivered gas concentration.

  • Novel methodology to perform sulfur hexafluoride (SF6

    The Exhalyzer D has been used previously to perform sulfur hexafluoride (SF 6) MBW, but based on the mainstream molar mass (MM) signal to calculate FRC and lung clearance index (LCI), and not on the true SF 6 concentration (11, 17). Using the mainstream MM signal is advantageous in that it does not require synchronization with respiratory flow.
