This study examines transnasal pressures and airflow measurements for assessing nasal airway patency using rhinomanometry. Calculating resistance from pressure and flow provides a practical index for nasal patency, aiding rhinological information exchange.

Area of Science:

  • Otolaryngology
  • Respiratory Physiology
  • Medical Instrumentation

Background:

  • Nasal airway patency is crucial for respiratory health.
  • Rhinomanometry is a key technique for its assessment.
  • Understanding measurement characteristics and error sources is vital.

Purpose of the Study:

  • To discuss the characteristics and measurement of transnasal pressures and airflow.
  • To review indices of nasal airway patency.
  • To explore components and adjuncts of rhinomanometric systems.

Main Methods:

  • Measurement of transnasal pressures and respiratory airflow.
  • Delineation of error sources (mucovascular fluctuation, face masks, nasal nozzles).
  • Integration of microcomputation and plethysmography as adjuncts.

Main Results:

  • Standardized rhinomanometry provides a practical index of nasal patency.
  • Transducers and microcircuitry offer reliability and economy.
  • Aerodynamic parameters for chronic obstructive nasal symptoms require further determination.

Conclusions:

  • Resistance calculation via transnasal pressure and flow is a practical index of nasal patency.
  • Standardized methods facilitate rhinological information exchange.
  • Continued research is needed to correlate aerodynamic parameters with specific nasal symptoms.
