An electronic device designed to calculate nasal resistance by measuring nasal airflow and the air pressure producing that flow within a patient's nasal passages, e.g., for the calculation of the nasal patency during ear/nose/throat (ENT) assessment/treatment. It is used to quantify the amount of nasal obstruction/congestion and is a computer-based device with dedicated software for data calculation, presentation (display), and storage purposes. This device will be powered via a connected computer and include or interface with a printer for hard copies of the graphical data presentation.

A line powered (AC- powered), or powered via a connected computer, electronic device designed to allow the internal profile of the nose to be recorded in order to quantify the degree of obstruction/congestion in the nasal cavities and provide monitoring of the consequences of therapy or surgery.A nosepiece conducts a sound pulse produced by an integrated sound generator to the patient's nose and the sound reflections from the nose are detected where changes in cross-sectional areas are encountered. It is a computer-based device with dedicated software for processing the output and return signals to produce plots of cross-sectional areas as a function of distance in the nose.

The VISIONAIR™ system is a software application intended to be used with third-party endoscopic systems in the measurement of the nasal respiratory airway. The VISIONAIR™ system measures the nasal respiratory airway from the endoscopic images taken in the region of the internal nasal valve (INV) and nasal cavum (NC).
