Cost-Effectiveness of Fractional Exhaled Nitric Oxide Suppression Testing as an Adherence Screening Tool Among Patients With Difficult-to-Control Asthma

Ultrasensitive Online NO Sensor Based on a Distributed Parallel Self-Regulating Neural Network and Ultraviolet Differential Optical Absorption Spectroscopy for Exhaled Breath Diagnosis

“…Fractional exhaled nitric oxide (FeNO) is an important biomarker gas used to identify airway diseases in the medical field because its concentration is strongly associated with a variety of respiratory diseases. − Currently, FeNO testing is widely used as an aid in the diagnosis of asthma, allergic rhinitis, and chronic obstructive pulmonary disease, − thus providing an effective way to monitor and adjust treatment plans. In addition to the medical field, measuring the concentration of NO in the atmosphere can help assess and monitor air quality − and, more specifically, assess safety hazards in the workplace. , Therefore, there is an increasing demand for the realization of high-precision online NO concentration detection at the ppb level.…”
