FeNO

FeNO (Fractional Exhaled Nitric Oxide):

FeNO is a simple breath test that measures the level of nitric oxide in a patient's exhaled breath.

This measurement is a direct indicator of eosinophilic inflammation in the airways, especially relevant in asthma.

Educating patients about their FeNO level helps them understand the biological basis of their asthma symptoms.

A high FeNO suggests active airway inflammation, even if symptoms are mild.

This helps patients see the "invisible" inflammation within their lungs.

It's crucial for tailoring anti-inflammatory medication, like inhaled corticosteroids.

Patients can learn to associate changes in their FeNO levels with the effectiveness of their treatment.

It reinforces the importance of consistent medication use, even when feeling well.

FeNO can also help identify poor adherence to inhaled steroids if levels remain high.

It aids in differentiating asthma from other respiratory conditions that don't involve this type of inflammation.

Patients understand that FeNO provides a personalized biomarker for their asthma management.

This objective measure empowers them to actively participate in optimizing their asthma control.
