FIGURE 1 Pressure-flow curves in mammals. Flow is expressed as vital capacity/second (VC/s). (A): During spontaneous breathing. Data of humans are from Mead and Whittenberger (1953) and guinea pigs from Lamm et al. (1984). (B): During more forceful expiratory effort at 49% (humans) or at 50% (hamsters) VC. Values of humans are from Hyatt and Wilcox (1963) and hamsters from Lucey et al. (1978).
