COMPUTER SIMULATION OF THE RESPIRATORY SYSTEM IN FORCED EXPIRATION

Barbara Juroszek, Jan Stanislawski

Abstract

The authors present a model of the respiratory system in forced expiration as an answer to the unknown pressure pulse excitation. The model has the form of a voltage divider circuit, where gas flow volume velocity is the current reaction (or the volume is the voltage reaction). The analysis is presented in time domain. The model’s finding is realized in two main stages. In the first stage an RCL net is built. On the basis of this structure the exciting signal is found in the form that the answer to the model is V(t) (or Q(t)), very similar to the real object’s answer, in the minimum mean-square-criterion.
