Volume-Pressure Hysteresis of the Lungs

Conference paper


Recoil due to tissue elastic forces and surface tension are the principal mechanisms which counter balance the inflating transpulmonary pressure of the lungs. The stress-strain properties of the elastic elements and surface tension-area relationships of surfactant are not sufficient to describe the mechanical behavior of the lungs because of the complex arrangement of the alveoli and alveolar ducts (Figure 1.).
