Modelling of Spirometry. Diagnostic Usefulness of Model Parameters

The respiratory system functioning is based on the ventilation mechanism. The quality of lung depends on the quality of lung ventilation. The spirometry assesses the efficiency of the pulmonary ventilation. In this paper, a new model of spirometry is presented. The model parameter estimates are obtained on the basis of spirometry measurements. The model parameters allow us to obtain the new information concerning breathing conditions. The parameters allow us to distinguish between healthy and diseased subjects. The experimental verification revealed the diagnostic usefulness of model parameters obtained on the basis of spirometry measurements.
