Measuring breathing and shortness of breath relief in asthma and COPD
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study looks at how different breathing tests (spirometry and impulse oscillometry) and a simple shortness-of-breath scale relate to how well you respond to a quick-relief inhaler (bronchodilator). It aims to improve how we measure treatment effectiveness in people with asthma or COPD.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a doctor’s diagnosis of asthma or COPD.
- You have had a lung function test (spirometry) showing a low ratio of air you can blow out in one second compared to total lung capacity.
- You have felt significant shortness of breath (scoring at least 10 out of 100 on a scale).
- For COPD: you have smoked at least 10 pack-years (e.g., one pack a day for 10 years). For asthma: you have smoked less than 10 pack-years in total.
- You can use breathing tests and answer questionnaires, and you have no other major health issues that affect breathing (like severe heart disease, lung damage, or active cancer) or severe obesity (BMI of 40 or higher).

This study tests whether a new approach can help relieve severe shortness of breath in people with COPD who are already on standard inhaler therapy. It may help you breathe easier and improve your daily life.
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 tests how a bronchodilator (a medicine that opens airways) affects breathing and exercise in people with COPD. It aims to understand if it helps you breathe easier during physical activity.
This study looks at how the volume of air you breathe in during a bronchodilator test affects response and lung airflow distribution in people with COPD. It may help improve how this routine test is done.
This study tests a new, low-power device worn on the body that may help diagnose asthma. It is for adults who are comfortable using mobile apps.
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
