What is it about?

Exhaled Nitric Oxide measurement (FeNO) is a simple test that has been used for many years in asthma management. It´s not clear yet if FeNO could be of value in COPD. This study is aimed to evaluate if FeNO could detect COPD patients at a higher risk of exacerbations

Why is it important?

For the first time, we demonstrate that COPD patients with persistent high FeNO levels are at a higher risk of moderate and severe COPD exacerbations.

Perspectives

FeNO could be used to target therapy (ICS) in COPD patients when aiming to prevent exacerbations
