The modelling of spirometry - the application for diagnostic purposes

The spirometry measurements assess the efficiency of the pulmonary ventilation. The respiratory system functioning is based on the ventilation mechanism. The basic degradation of the patient’s breathing condition are obstructive, restrictive and mixed pulmonary diseases. In this paper, a new model of the spirometry measurement 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. They also allow us to distinguish between healthy and diseased subjects. The verification, based on the disease simulation, revealed the diagnostic usefulness of the model parameters acquired on the basis of spirometry measurements.
