Conventional methods of testing lung functioning demand a specific respiratory action of the patient. In contrast, the forced oscillation technique (FOT) provides measurements obtained with a minimal cooperation of the subject. The aim of this study is to verify the usefulness of the forced oscillation technique modelling in respiratory system diagnosing. In order to do this two models of FOT measurements have been considered: the four-parameter model (4p) and the six-parameter model (6p). The question is whether the models' parameter estimates can be accepted for diagnostic purposes. To answer the question the parameter estimates and their precision were calculated and the results obtained were confronted with the parameter values in population of healthy patients and for patients with lung diseases. The results obtained showed that the FOT measurements and modelling allow us to achieve such parameter estimates that could be applied for diagnostic purposes. Precision and accuracy of the parameter estimates are sufficiently good for unmistakable distinguishing between healthy and diseased subjects.
