Concordancia entre dos dispositivos de medida de óxido nítrico exhalado

The two analyzers, NIOX-MINO® and NIOX®, were not equivalent. There was good agreement between the FENO values measured with the two devices. Measurement of FENO with the portable electrochemical sensor-based analyzer (NIOX-MINO®) is valid and feasible in children older than 5 years.
