    Area of Science:

    • Otolaryngology
    • Medical Instrumentation
    • Respiratory Physiology

    Background:

    • Rhinomanometry is crucial for assessing nasal airway resistance.
    • Manual measurement and calculation can be time-consuming and prone to error.

    Purpose of the Study:

    • To develop and validate an automated rhinomanometer system.
    • To improve the efficiency and accuracy of nasal airway resistance measurements.

    Main Methods:

    • A microprocessor-controlled system was developed for automated calibration and data acquisition.
    • Pressure and flow signals were recorded 200 times per second during breathing.
    • Calculations of nasal airway resistance were performed automatically.

    Main Results:

    • The automated system demonstrated accurate calibration using a standardized test-nose.
    • Pressure-flow curves were displayed in real-time.
    • A close correlation was found between automatically calculated and manually derived nasal airway resistance data.

    Conclusions:

    • The automated rhinomanometer effectively facilitates rhinomanometric procedures.
    • The system provides accurate data on nasal airway resistance.
    • This technology enhances clinical assessment of nasal obstruction.
