Abstract

A new method is presented for characterizing the dynamic chemoreceptor response of the human ventilatory system to stimulation by CO₂ using the Laguerre expansion technique (LET). The transfer function of the system relating the inspired CO₂ as the input to the tidal volume as the output is identified by the LET. The identified transfer function shows an underdamped behavior with delay
