[Air pressure and flow in the nose6 represented in a double-logarithmic system (author's transl)].

The x-y-recording system is developed from rhinorheomanometry in written polygraph tracings sharing a common time base. Furthermore, using tracing in a double-logarithmic diagram, the pressure-versus-flow diagram can easily be expressed with a straight line. Using fractional numbers as exponents, a precision is achieved that has previously not been posisible. The pressure-versus-flow diagram of the whole nose can easily be described, by calculation and by tracing, as the diagram of the right and left nasal cavities. The physiological-medical use of the system is shown. In order for the system to be routinely employed, a direct writing apparatus would be necessary.
