Abstract

The last comprehensive publications about the theory and practice of rhinomanometry appeared more than 20 years ago. Since the 1980's, the general progress of sensor techniques, fluid physics and data processing was accompanied by the permanent work of the authors to analyze the errors of rhinomanometry and to create a fundament for a contemporary and practical method that can be used in functional diagnostics of the nasal air stream. In this special document, the objectives and measurement principles, as well as the history of rhinomanometry are described in the first three chapters. It is pointed out, that the key parameters are not only intranasal pressure and flow, but also the factor time. The technical requirements as following from the dynamics of breathing are described. The process of averaging of rhinomanometric data lead to a separate and time-dependent analysis of the changes of pressure and flow and implicated the introduction of the 4 breathing phases (ascending and descending curve part in inspiration and expiration) into rhinomanometry and is therefore called 4-Phase-Rhinomanometry (4PR). Chapter 4 is containing a comprehensive analysis of the practical errors, which may follow neglecting the 4 breathing phases....Continue Reading
