Reslink exhaled nitric oxide detector

Fractional exhaled nitric oxide (FeNO) is produced by airway cells, and its concentration is highly correlated with the number of inflammatory cells, which can be used as a biomarker of airway inflammation. Exhaled nitric oxide concentrations can be detected through mouth breath test and nasal breath test. The measurement of exhaled nitric oxide is widely used in the diagnosis and monitoring of respiratory diseases.

Inflammatory factors and drugs affect the concentration of FeNO by acting on iNOS (nitric oxide synthase). The concentration increases during inflammation and decreases during anti-inflammatory process. Therefore, FeNO, as a biomarker of airway inflammation, is widely referred to in the diagnosis and monitoring of bronchial asthma, chronic cough, COPD, etc.

In 2003, the FeNO measurement technology was approved by the US FDA for clinical use; in 2005, the American Thoracic Society and the European Society of Respiratory Diseases published technical guidelines for FeNO detection. Subsequently, the American Thoracic Society clarified the clinical application value, application scope and detection methods of FeNO, and issued the FeNO clinical guidelines in 2011. In 2017, the European Society of Respiratory Diseases developed technical standards for exhaled biomarkers of lung disease, including FeNO. In 2020, China's guidelines for the prevention and treatment of bronchial asthma clarified that FeNO measurement can evaluate the level of airway inflammation and asthma control, and can predict and evaluate the response to inhaled hormone therapy.

Reslink adopts Novlead's new generation of electrochemical sensor system. The product features are as follows:
