The ability to reliably measure total respiratory input impedance Z/sup rs/ from 0.25 to 4 Hz has only recently been reported and only in healthy subjects. The real part of Z/sup rs/ decreased substantially with frequency. One explanation is provided by the Otis model, which contains parallel resistance-compliance time-constant inhomogeneities. Several investigators have suggested the use of this model at the level of estimating its parameters by fitting the model to data. Such an approach… CONTINUE READING
