Elasticity Properties of Lung Parenchyma Derived from Experimental Distortion Data

Distortion data for dog lungs obtained experimentally by Hoppin et al. (1975) are used to arrive at a general mathematical model (strain energy function) which describes finite deformation of lung parenchyma. The strain energy function is correlated with average alveolus model proposed by Frankus and Lee (1974). The latter predicts parenchyma distortion properties from uniformly ventilated pressure-volume data only
