Nitric oxide (NO) is a molecule that performs many functions in the human body. The entire respiratory tract can produce NO, but the highest production occurs in the upper respiratory tract, in the paranasal sinuses in particular. The aim of the present study was to assess a new nasal NO (nNO) measurement method using the Niox MINO Nasal® device (Aerocrine AB, Solna, Sweden) and a special procedure, in order to compare the nNO values obtained in 32 healthy subjects with the values found in the international literature. The measured normal nNO values were equal to 426.76±143.27 ppb, with a 95% confidence interval [160.22-733.30]. Males had an average nNO value equal to 446.76±133.63 [178.64 – 714.02], whereas in females the average value was 403.80±154.90 [94.00-713.60]. This study allows us to confirm that we have been able to establish the normal range of nitric oxide quantity produced in the nasal/sinus cavities of healthy individuals using the Niox MINO Nasal® device and tidal-breathing with velum-closure manoeuvre.

Abstract

Nitric oxide (NO) is a molecule that performs many functions in the human body. The entire respiratory tract can produce NO, but the highest production occurs in the upper respiratory tract, in the paranasal sinuses in particular. The aim of the present study was to assess a new nasal NO (nNO) measurement method using the Niox MINO Nasal® device (Aerocrine AB, Solna, Sweden) and a special procedure, in order to compare the nNO values obtained in 32 healthy subjects with the values found in the international literature. The measured normal nNO values were equal to 426.76±143.27 ppb, with a 95% confidence interval [160.22-733.30]. Males had an average nNO value equal to 446.76±133.63 [178.64 – 714.02], whereas in females the average value was 403.80±154.90 [94.00-713.60]. This study allows us to confirm that we have been able to establish the normal range of nitric oxide quantity produced in the nasal/sinus cavities of healthy individuals using the Niox MINO Nasal® device and tidal-breathing with velum-closure manoeuvre.
