A case study on asthma diagnosis and management using FeNO testing

Carol Stonham MBE, a Medical Advisory Board member, has conducted this study. Carol became a registered nurse in 1986 and transitioned to primary care from acute hospital settings by 1990. Currently, she works at the Gloucestershire ICB and heads the Respiratory Clinical Programme Group, while also co-leading the NHSE South West Respiratory Network.

This case study aims to showcase the value of Fractional exhaled Nitric Oxide (FeNO) testing in asthma care and explore why the NObreath® FeNO device is the ideal choice. The NObreath® performs a non-invasive test that measures nitric oxide levels in exhaled breath. Elevated nitric oxide levels may suggest airway inflammation, a typical characteristic of allergic asthma.

Asthma is a common respiratory condition impacting approximately 5.4 million people in the UK. Tragically, a substantial number of asthma-related deaths occur annually, with a high percentage of these deaths considered preventable. This highlights the value of increasing awareness about FeNO testing and its crucial role in asthma diagnosis and management.

Carol states:

When looking into the different devices, the NObreath® suited what I was looking for. I wanted something that had a really good approval process as I wanted something that would be reliable. I wanted something that was going to be easy for the patients to use but also easy to teach the healthcare professionals to use. The cost always comes into it, this is something we always need to be careful about within the NHS. Finally, it needed to be something that would offer a sustainable service for a long time.

Carol continues, “The thing I like about this device is the ease of use, I like that it is portable, so if you have this in a practice setting you can move it around from A to B simply. In my experience, I’ve had patients as young as 5 and as old as 95 able to do the test. It is an all-age easy-to-use device, it doesn’t take long either, you can do it really quickly in a consultation.”
