ABSTRACT
The authors studied the pressure/flow signals generated during active anterior rhinomanometry of 25 subjects, presenting a normal transnasal breathing. By means of a Fourier transformation, the frequency content of these signals was analyzed. This investigation demonstrated clearly that signals with a frequency of more than 50 Hz no longer yield any further information about the transnasal ventilation.
