  • Inert gas washout: background and application in various lung

    Abstract. Multiple breath inert gas washout (MBW) is a lung function technique to measure ventilation inhomogeneity. The technique was developed more than 60 years ago, but not much used for many decades. Technical improvements, easy protocols and higher sensitivity compared with standard lung function tests in some disease groups have led to a recent renaissance of MBW.

  • WORKSHOP REPORT - ATS Journals

    MBW Testing An old technology that has been recently revisited, the MBW test is a gas washout technique. The technique was introduced by Ward S. Fowler in 1952. He described a method to measure nitrogen clearance curves of single breaths in healthy subjects and those with cardiorespiratory disease to quantifythe “unevennessof gas distribution” (6).
