Sumario:BACKGROUND: Despite the widespread use of fractional exhaled nitric oxide (FE(NO)) as a biomarker of airways inflammation, there are no published papers describing normal FE(NO )values in a large group of healthy adults. OBJECTIVE: The aim of this study was to establish adult FE(NO )reference values according to the international guidelines. METHODS: FE(NO )was measured in 204 healthy, non-smoking adults with normal spirometry values using the on-line single-breath technique, and the results were analysed chemiluminescently. RESULTS: The main result of the study was the significant difference in FE(NO )values between men and women, thus indicating that gender-based reference FE(NO )values are necessary. The FE(NO )levels obtained at expiratory flows of 50 ml/s ranged from 2.6 to 28.8 ppb in men, and from 1.6 to 21.5 ppb in women. CONCLUSION: We propose reference FE(NO )values for healthy adult men and women that could be used for clinical and research purposes.
