Interpreting changes in FeNO results for better outcomes
FeNO is a great asthma management tool and, to optimise treatment, it’s helpful to understand the clinical context for each patient so they can reach the right FeNO level for them. The American Thoracic Society (ATS) defined...
What is a “normal” FeNO value?
Measuring FeNO is straightforward and gives results at the point-of-care. The American Thoracic Society sets out clear cut points defining low, normal and high FeNO. But where do you begin?
