Abstract

The main purpose of this paper is presenting the new hybrid (pneumo-numerical) model of lungs as well as some results of its successful experimental examinations. This kind of models enables simulation of different lung properties including rheological and nonlinear features and may be also applied to develop different lungs mechanics measuring systems. The presented model design approach is based on the linear impedance transformation from the numerical to pneumatic signal environments.<br />Some metrological aspects of the model design and function are considered e.g. statical and dynamical accuracy of the impedance transformation.<br />The hybrid lungs model was experimentally verified in the typical respiration-model set-up evidencing its good dynamical and statical properties.
