What do the FeNO values mean?
The Vivatmo device shows you whether your measured values are in the green, amber or red range. The trend arrow pointing upwards (∧) indicates a higher value than the previous reading. Conversely, the trend arrow pointing downwards (∨) shows declining values. This allows you to compare how you subjectively feel with measured inflammation values.
Vivatmo me measures what is known as the FeNO value. FeNO stands for “fractional exhaled nitric oxide (NO)”.
