Testing a breathing device to diagnose asthma
Part of Lungs & breathing clinical trials.
This study tests a portable handheld device that measures airway function to help diagnose asthma. Researchers want to see if this device can accurately identify asthma in people with breathing symptoms like wheezing and shortness of breath.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old
- You have had asthma-like symptoms (wheezing, shortness of breath, chest tightness, or cough) for at least 2 months
- You have not had a respiratory infection (like pneumonia, bronchitis, flu, or COVID-19) in the past 3 months
- You are not a current smoker and have not smoked within the past 6 months (or smoked less than 10 packs total in your lifetime)
- You do not have other chronic lung diseases like tuberculosis or interstitial lung disease
- You have not taken inhaled corticosteroid asthma medications in the past 3 months

This trial is studying people with chronic lung conditions, like COPD or asthma, to find treatable traits. It also includes healthy volunteers for comparison, to better understand what makes these diseases different and how to personalize treatment.
This study tests a new portable device that measures how well your lungs work by having you breathe into a mouthpiece. Researchers want to see if this device can accurately identify different chronic lung conditions like COPD, asthma, bronchiectasis, and others.
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.
This study compares a new breathing device to standard tests for diagnosing asthma and COPD. If you have been referred for breathing tests because your doctor suspects asthma or COPD, you may be able to join.
This study tests if a small, low-power device placed on the skin can help diagnose asthma. It is looking for adults who are comfortable using a mobile app.
This study is testing a device called AeviceMD that listens for wheezing—a whistling sound when breathing—to help doctors quickly spot asthma attacks. If you or your child is in the emergency room with a sudden asthma flare-up, you may be able to join.
