A FeNO level greater than 40 parts per billion – or ppb – means asthma is seven times more likely, making FeNO a useful biomarker in suspected cases. But why is FeNO higher in asthma patients? This episode looks at the science.

Over-reliance on short-acting β2-agonists, known as SABA, may indicate poor asthma control. Some people are collecting more than 50 canisters a year when the recommendation is one or two! In this episode, we look at the facts and...

In this episode, we’re looking at what is important when measuring FeNO levels and how the technology behind NIOX VERO® addresses these needs.

One part per billion. It’s difficult to picture it but this microscopic measure is an intrinsic element of the technology behind FeNO testing and its practical application in asthma care.

As many people know, FeNO stands for fractional exhaled nitric oxide. Changes in individual FeNO levels provide vital clues to how asthma treatment is working. Interpreting the variations is quite straightforward. This episode looks in detail at using FeNO testing to achieve everyone’s personal best.

Measuring FeNO is straightforward and gives results at the point-of-care. The American Thoracic Society – known as the ATS – sets out clear cut-off points defining low, normal and high FeNO. But where do you begin?

FeNO testing has really gained traction over the last five years and thousands of physicians use it every day to improve patient outcomes. Most national and international societies recognise the value of FeNO testing to help achieve more accurate diagnosis and better asthma management, and now include FeNO in their recommendations.

Symptoms worsen for around a third of pregnant woman with asthma yet many are reluctant to take medication...

What has the chemical formula KMnO4, is purplish-black when solid and intense pink-purple in solution? It’s potassium permanganate – and it’s a vital part of FeNO testing! But it’s no mixer. This episode looks inside the NIOX VERO® and examines why alcohol is off-limits for FeNO.

All exhalations are not the same when it comes to testing fractional exhaled nitric oxide (FeNO). Exhaling for 10 seconds for all adult patients is one of the most important steps. This article looks in detail at why this timing is so central to success.
