Optimal sample frequency in computerized rhinomanometry. Development and method

F Versnick et al. Rhinology. 1991 Dec.

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.
