Total NO uptake over a 60 seconds time period for pulsed and constant concentration delivery. Plotted with varying (a) tidal volume, (b) inspiratory time fraction, (c) breathing frequency, (d) functional residual capacity (FRC), (e) expiratory time constant, and (f) varying FRC together with tidal volume, where tidal volume is scaled in proportion to FRC. When not the varied parameter, the following values were used: FRC = 3000 ml, DLNO = 150 ml/min/mm Hg, tidal volume = 500 ml, breath frequency = 12 min-1, inspiratory time fraction = 1/3, and expiratory time constant = 0.6 s.
