Measurement of FeNO in Young Children With the NIOX VERO

FeNO measurements provide the physician with means of evaluating an asthma patient's response to anti-inflammatory therapy, as an adjunct to the established clinical and laboratory assessments in asthma. Interpretation of FeNO profiles is based on the nitric oxide plateau. To achieve plateau, the duration of exhalation must be sufficient (at least 4 seconds for children \ 6 seconds for children \> 12 years (ATS/ERS, 2005). Measurement of FeNO using the 6-sec mode may provide a viable alternative in children as young as age 4 years who may have difficulty maintaining exhalation for a full 10 seconds.
