The electropneumatic gyrator as a tool for physical modeling of lungs

Unlike classical physical lung models, the model presented in the paper makes it possible to realize any input impedance of lungs representing their complex mechanical structure. The crucial element of the model is the electropneumatic gyrator converting the input impedance of the electrical network, connected to electrical ports of the gyrator, into the inversely proportional pneumatic impedance obtained in its pneumatic channel. The gyrator is built up as a cross-connection of electrically controlled flow and current sources. Experimental investigations demontrated a very good static and dynamic accuracy of the gyratory conversion. The characteristic pressure and flow courses illustrating dynamical behavior of the gyratory model of lungs are also included.
