Abstract

The study deals with design and implementation of a mathematical model of the human respiratory system according to its anatomical structure. The model is designed in order to simulate distribution of important intrapulmonary parameters along the bronchial tree such as pressure amplitude, tidal volume and regional mechanical lung properties. The model is based on the lung morphology and electro-acoustic analogy is used to design the model. The model allows changing the mechanical parameters of the airways and alveolar compliance. conducted simulations suggest that efficiency of artificial lung ventilation is significantly dependent on the mechanical properties of lungs.
