Figure 3.
Summary of typical recruitment events for modest variability in airway cross-sectional area d = 0.2 and fixed tidal volume VT = 10 ml kg−1. Modest collapse: (a) time-trace of airway pressure during airway recruitment for C = 0.5; (b) time-trace of the number of recruited airways. No collapse: (c) time-trace of airway pressure during airway recruitment for C = 1.0; (d) time-trace of the number of recruited airways for C = 1.0. Shaded areas in (a–d) correspond to 1 s.d. from the mean for 100 repeated simulations of the model. Other parameters are chosen as in table 1.
