[Human respiration models and critical observations on respiratory mechanical parameters]

This paper is meant to summarize and compare certain conceptions of modelling human breathing as published by several authors. By means of respiratory mechanics models various definitions of lung mechanics parameters are stated. In lung function diagnostics and artificial ventilation control the generally used parameters are based on different conceptions of models of respiratory processes. For this reason it is necessary to agree on definitions of comparable parameters and to make clear meaning of terms as a base for giving reproductive measurement instructions and obtaining comparable measuring results.
