World Lung Day is an annual occurrence on the 25th September, which aims to promote better lung health. Poor lung health can lead to many conditions, including asthma, a chronic condition of the lungs, causing difficulty in breathing, that affects over 12% of the UK population1. But thanks to technologies like Fractional exhaled Nitric Oxide (FeNO) monitoring with the NObreath®, Healthcare Professionals can offer patients a quick, easy, and non-invasive, method which helps in the diagnosis and monitoring of asthma.
Airway inflammation is a central process in asthma and other lung diseases2. Nitric Oxide (NO) is naturally produced by your body to help combat inflammation and when your airway is inflamed, NO is produced in the lungs and exhaled on the breath3. NO is exhaled in very miniscule particles known as Fractional exhaled Nitric Oxide (FeNO) and is measured in parts per billion (ppb).
A FeNO test can help to differentiate between allergic (eosinophilic) and non-allergic asthma4, identify patients who do/do not require ongoing treatment5, and help predict and prevent asthma attacks6.
To learn more about how FeNO testing can improve asthma care and more, please watch The Role of FeNO in Primary Care Respiratory Diagnostics.
