Official title
A Randomized, Multi-Center, Single-Visit, Clinical Investigation to Assess the Degree of Agreement and Feasibility of Measuring Exhaled Nitric Oxide in Children, Aged 4-6 Years Old, With the NIOX VERO Using the 6 Second Exhalation Mode as Compared With the 10 Second Exhalation Mode
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 \<12 years and \> 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.
