The deflation pressure-volume curves of the lungs of a wide range of mammalian species [cat, dog, fruit-bat, goat, hamster and human] were studied to compare their mechanical properties. A monoexponential mathematical function of the form V = Vmax-(Vmax-Vo)e-kP was fitted to the deflation data. The bulk stiffness index k (approximately 0.12 cm H2O-1) varied little over the 105-fold range of animal body weight. This range of k was far smaller than found in man in the presence of pulmonary parenchymal disease. The intrinsic stiffness characteristics of most mammalian lungs are similar.
