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).
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 typically be line-powered (AC-powered) or powered via a connected computer and include or interface with a printer for hard copies of the graphical data presentation.
