摘要

After introducing the averaging procedure, described in chapter 4, which resulted in the observation of loops as the common form of the rhinomanometrical xy-curve, it became evident that it was necessary to reconsider the existing physical and mathematical concepts of rhinomanometry and the underlying flow phenomena within the nose.The diagnostic intention of rhinomanometry is to obtain an impartial measure of the energy expended or the work performed during breathing to generate the flow of air through the nose as it is conditioned for the lungs. Except for the region of the anatomic structures of the "nasal valve", nasal breathing is about alternating ventilation of air in both directions through an irregular cavity with a narrowing at both ends. Rhinomanometry ostensibly measures changes in the physical parameters transnasal pressure and transnasal flow during the ventilation of the entire nasal cavity. The fluid-dynamics interpretation of several parts of this cavity by comparing it with streamed cavities within the technology becomes interesting only if one attempts to interpret an at first sight unexpected rhinomanometrical result anatomically. Previous comparisons of the nose with flow-bodies and using technical terminology that does not consider the alternate breathing through the nose may be of limited practical value.
