The paper describes a lung model which illustrates the pressure-volume-flow relationships in the lungs. The model includes three airway segments in series; the resistance of one of them is a function of transmural pressure and a constant related to airway compressibility. The model can be used to obtain IVPF curves and flow-volume curves, and various assumptions concerning the distribution of airway resistance, the magnitude of lung elastic recoil; and other factors can be tested with it.
