Certain gases in human breath are known to be indicators of the presence of diseases. These gases have been identified as biomarkers using different instruments, mainly based on chemical methods, e.g. gas chromatography or chemiluminescence. The article describes an application one of the most sensitive optoelectronic method – Cavity Enhanced Absorption Spectroscopy (CEAS) to investigation of fractional exhaled nitric oxide (FeNO). Measurement of FeNO concentration is a quantitative, non-invasive, simple, and safe method of respiratory...
