FeNO Detection Method Based on Highly Sensitive Mid-Infrared Absorption Spectroscopy
The fractional exhaled nitric oxide (FeNO) is closely related to lung and respiratory diseases. Authorities such as the US Food and Drug Administration (FDA), European Respiratory Society (ERS), and American Thoracic Society (ATS) have successively identified FeNO as an asthma biomarker and listed FeNO as a routine inspection item for respiratory diseases. In order to meet the needs of high-sensitivity monitoring of FeNO, a mid-infrared wavelength modulation laser absorption spectrometer is developed in this paper. The problem of cross interference of CO2 spectral lines is solved by the method of multiple linear regression, and the detection limit of NO reaches
