A Quick, Easy Way to Measure Airway Inflammation for Better Asthma Treatment
When you have asthma, your airways become inflamed, making it hard to breathe. There are different types of asthma and there are many diseases that have the same symptoms as asthma.
Knowing if your airways are inflamed can help your doctor make the right diagnosis, find the best management plan and monitor your asthma better. One way they can do this is with a FeNO test.
FeNO stands for fractional exhaled nitric oxide. When you breathe out, your breath can show if you have inflamed airways. A FeNO test measures the amount of nitric oxide in your breath. This test helps doctors tell if and how much inflammation you have in your airways.
