  • Impact of leaks in sulfur hexafluoride and nitrogen multiple

    Oct 19, 2018 · The study is relevant for a specific N 2 MBW system, but the authors mention that sulfur hexafluoride (SF 6) MBW measurements are prone to similar leaks. This is correct, but the impact of inspiratory leaks in SF 6 MBW systems is entirely different because SF 6 is washed out with air.

  • Simultaneous sulfur hexafluoride and nitrogen multiple-breath

    Multiple-breath washout (MBW) can be performed with different gases (sulfur hexafluoride (SF 6­) and nitrogen (N 2 )) and different devices, all of which give discrepant results. This study aimed to confirm previously reported differences and explore factors influencing discrepant results; equipment factors or the physical properties of gases used. Methods Healthy controls (HCs) and participants with cystic fibrosis (CF) completed MBW trials on two commercially available devices (Exhalyzer
