Abstract
This chapter treats the basic principles of estimating the respiratory impedance from measurements performed with the forced oscillation lung function test. First, the non-parametric identification of the respiratory impedance is presented by means of spectral analysis. Next, a comparison with most representative parametric models from the literature for assessing respiratory input impedance shows that FO models are more efficient than integer-order models. It is also shown that the FO model in four parameters available from the literature is limited to the low frequency range of estimated impedance, whereas a model in two FO terms is more efficient at mid-range frequencies.
