Using sound waves to collect lung mucus samples in COPD patients
Part of Lungs & breathing clinical trials.
This trial is testing whether a device that uses sound waves can help collect lung mucus samples more easily in people with COPD. It compares two groups: current smokers and ex-smokers, to see if the device works differently for them.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 70 years old and have COPD diagnosed by a breathing test.
- Your lung function is at least 50% of what is expected for your age and size.
- You are either a current smoker (at least 15 cigarettes a day for the past year) or an ex-smoker (stopped smoking at least a year ago).
- You have a BMI between 18 and 38.
- You do not have certain heart conditions, implants, or other health issues that could make the procedure unsafe.
- You have not had certain medications or respiratory infections recently.

This trial is testing a new breathing device that may be as accurate as standard tests for diagnosing asthma and COPD. It could offer a simpler and quicker way to check your lung health.
This study tests two breathing techniques—autogenic drainage and the flutter device—to see if they help people with moderate COPD breathe easier. It compares these methods to find which one works better for clearing mucus and improving lung function.
This study tests a portable device that measures how well your lungs work by sending gentle sound waves or pulses through them. It aims to see if this new device can accurately detect and differentiate various chronic lung conditions, potentially offering a simpler and more accessible way to monitor respiratory health.
This study tests whether wearable medical devices can help monitor your COPD symptoms at home. You will use a smartphone app and a small chest patch to track your breathing, which may help you and your doctor better manage your condition.
This trial compares different vibratory devices that help loosen and clear mucus from the lungs. It may help by showing which device works best and is safest for people who need airway clearance therapy.
