Fractional Exhaled Nitric Oxide – FeNO

Fractional exhaled nitric oxide – FeNO or Nobreath is a good marker for eosinophilic airway inflammation, and is considered to be a good indicator of corticosteroid response.

The production of nitric oxide is often found to be higher in inflammatory conditions such as asthma and therefore FeNO monitoring can be used for the detection and management of such conditions2, but also to differentiate between COPD, ACOS and other interstitial lung diseases that are not assessed by other means, such as lung function.
Nitric oxide measurement is not intended as a stand-alone method for diagnosis and should be used in conjunction with other evaluation methods and tests4. Fractional exhaled nitric oxide measurement is a simple, rapid, highly reproducible, and non-invasive method of airway inflammation assessment, which until now, has been an expensive test to deliver in everyday practice.

Benefits of performing FeNO tests:

• Non-invasive, quick and easy to perform.
• Aids in asthma management, assisting the correct prescription and making monitored adjustments
• Shows patient adherance to treatment.
• Aids in identifying good and poor adherence to corticosteroid treatment.
• Good indicator of corticosteroid response.
• Shown to be superior to the majority of conventional tests of lung function, such as peak flow recording and spirometry.
• Aids in differentiating between allergic (eosinophilic) and non-allergic asthma.
