Device to Monitor Asthma by Measuring Nitric Oxide in Breath
Part of Immune system & allergy, Lungs & breathing clinical trials.
This trial tests a handheld device that measures nitric oxide in your breath to see if it can help monitor asthma. You may qualify if you have uncontrolled asthma and can use the device at home.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 5 years or older.
- You must have a diagnosis of asthma.
- For the uncontrolled asthma group: you must have had asthma symptoms on at least 2 days in the last week.
- Your FeNO level (a measure of airway inflammation) must be at least 30 parts per billion (or 25 if you're under 18).
- You cannot have used certain asthma medications recently, like inhaled steroids (within 2 weeks) or steroids by mouth (within 4 weeks).
- You cannot be a heavy smoker (10 pack-years or more) or have smoked in the last 6 months.

Other trials that look related to this one.
This trial is testing whether a simple breath test called FeNO can help doctors diagnose asthma more accurately. It's for people who have symptoms that might be asthma, but haven't been diagnosed yet.
This study looks at how certain markers of inflammation (called T2) affect asthma. By joining, you'll help doctors understand the burden of this type of inflammation, which could lead to better treatments for people like you.
This study tests a new way of measuring lung function (called impulse oscillometry) during routine asthma check-ups. It looks at whether this helps doctors decide when to change asthma medicines.
This trial uses a simple inflammation test (inflammometry) to help diagnose asthma more accurately in people aged 6 and older who have been sent by their primary care doctor for standard breathing tests. It aims to improve the diagnosis process and reduce delays.
This trial studies new technologies to help doctors diagnose asthma and better understand airway inflammation. It may help you (or healthy volunteers, if eligible) by allowing your breathing tests and inflammation markers to be measured with newer diagnostic tools.
This study compares simple breathing tests (oscillometry and FeNO) used by your primary care doctor against a specialist's diagnosis to see if they can accurately tell if you have asthma or COPD. If you have symptoms like wheezing, cough, or shortness of breath but haven't been diagnosed yet, this trial may help improve how these conditions are found.
