Lezhongsheng - Model ZK-NR-100A -Nasal Ventilation Measuring Instrument

The nasal resistance meter offered by Lezhongsheng is an advanced tool utilized within the Otolaryngology Department for the precise measurement and assessment of nasal ventilation. This instrument determines the resistance values of nasal expiration and inspiration, aiding in the diagnosis of nasal patency and obstruction, which can range from normal to severe levels. The device employs cutting-edge technology, such as a gear-type hand-held measurement method, disposable pressure extraction sensors to combat cross-contamination, and advanced digital signal processing to ensure accuracy. These innovations make it suitable for distinguishing nasal obstruction factors, assessing surgical indications, and evaluating allergen-induced nasal responses. As a result, it provides significant clinical value by accurately determining the degree of nasal obstruction and confirming non-nasal factors causing oral respiration.
