Professor David Price describes the mounting evidence or FeNO testing to improve asthma treatment in both primary and secondary care.
How FeNO fits into the asthma routine for primary and secondary care
What if someone told you it was possible to start reducing asthma exacerbations by up to 50% with a simple desktop device, right there at the patient’s appointment? With FeNO testing, you can. To get an idea...
How FeNO helps stop the overuse of SABA in asthma
Believe it or not, some asthma patients are collecting more than 50 SABA canisters a year. The recommendation is two! We’re looking at the facts about...
Asthma control: The 10-point checklist
This article summarises 10 top tips from the experts at the Royal College of Physicians in London and the American Lung Association.
A sensitive issue: Why FeNO is measured in parts per billion
FeNO levels are measured in parts per billion – think 1 second in 32 years! Why is this so crucial for accuracy? Read our article now.
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?
10 top tips on managing asthma through the September peak
Lots of us are looking forward (or not!) to the long summer holiday when the schools are shut and the general pace of life slows down. The next couple of months is also a good time to...
Controlling asthma in pregnancy

Managing asthma with FeNO testing to improve patient outcomes
Asthma is characterised by chronic airway inflammation. It is one of the main causes of the exacerbations – or asthma attacks – that can have such a debilitating impact on...
Why FeNO and alcohol don’t mix
The ability to test and obtain results at the point-of-care means FeNO (fractional exhaled nitric oxide) is the most convenient biomarker of airway...
Easing the burden of pollution in paediatric asthma
Air pollution has long been linked to asthma in children and known to contribute to worsening symptoms. According to the WHO, 4.2m deaths occur every year from...
The FeNO countdown
Exhaling for 10 seconds for all adult patients is one of the most important steps in FeNO testing. This article looks in detail at why this timing is so...
Understanding Type 2 inflammatory pathways
Interest in precision medicine is growing. For asthma, the challenge lies in differentiating between the various types of the disease to allow physicians...
How FeNO-driven asthma management can save healthcare resources
Since its discovery in the 1990s, FeNO (fractional exhaled nitric oxide) has proved to be a helpful biomarker to guide asthma diagnosis...
Can FeNO testing replace induced sputum and blood eosinophils to support asthma diagnosis?
To date, there is no single test available to diagnose asthma. Alongside traditional methods such as spirometry and peak expiratory flow...
How can FeNO help optimise asthma treatment and improve ICS adherence?
Inhaled corticosteroids (ICS) are the cornerstone of asthma controller therapy. However, patients don’t always adhere to...

A look at what is important when measuring FeNO levels and how the technology behind NIOX VERO® addresses these needs...
Interpreting FeNO test results to enhance asthma management
FeNO values are used to indicate the likelihood that a patient has airway inflammation, a key characteristic of asthma. Knowing a patient's FeNO level can help diagnose asthma more accurately...
Using FeNO to control seasonal asthma
The colder months of the year see many asthmatics experience a worsening in their symptoms as autumn and winter bring a rush of triggers. From cold air outside to central heating within...
New study shows FeNO testing with NIOX VERO® is not an aerosol-generating procedure (AGP)
A new paper has been published demonstrating that FeNO testing is not an aerosol-generating procedure (AGP). Read our overview to find out how FeNO testing with NIOX VERO® can be safely continued.
