  • Nitrogen Washout an overview ScienceDirect Topics

    The nitrogen washout technique also is based on the principle of conservation of mass of an inert gas—in this case, the nitrogen normally resident within the lungs. The subject breathes on a mouthpiece that, at the end of a relaxed tidal exhalation, is connected to an inspiratory source of oxygen (Figure 94), while the subsequent exhaled gas is directed by oneway valves into a
