Examples of N2 washout and CO2 versus volume curves for the single (hollow square) and four compartment (filled square) physical models. a Inspiratory (black) and expiratory (gray) end-tidal N2 fractions during one washout maneuver of each model. b Expired CO2 versus volume, the dashed line represents the dead space volume as calculated by Fowler’s technique
