Multiple breath nitrogen washout: a feasible alternative to

Background: The lung clearance index (LCI), measured by multiple breath washout (MBW), reflects global ventilation inhomogeneity and is a sensitive marker of early cystic fibrosis (CF) lung disease. Current evidence is based on a customized mass spectrometry system that uses sulfur hexafluoride (Sulfr hexafluoride) as a tracer gas, which is not widely available. Nitrogen (N2) washout may be better suited for clinical use and multi-center trials.Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Multiple Breath Nitrogen Washout: A Feasible Alternative to

Feb 15, 2013 · Therefore, the current customized system is neither suitable for multi-center clinical research nor clinical practice. Multiple breath nitrogen washout (MBW N2) offers a possible alternative to mass spectrometry based SF 6 washout (MBW Sulfr hexafluoride). N 2 is a resident gas and permeates even poorly ventilated lung units, which may not be the case during MBW Sulfr hexafluoride. Thus, the physiological attributes of the respective tracer gases may lead to differences in measurements obtained with the two systems.Get price
