Sputum collection with a chest vibration device for COPD
Part of Lungs & breathing clinical trials.
This study tests whether a chest vibration device helps people with COPD produce sputum (phlegm) more easily during a breathing test. It may help researchers collect better samples to understand and treat COPD.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 70 years old.
- You have been diagnosed with COPD (confirmed by a breathing test).
- Your lung function is between 50% and 80% of normal for your age.
- You are either a current smoker (at least 15 cigarettes a day for the past year) or an ex-smoker (quit at least a year ago), with a smoking history of at least 10 pack-years.
- You do not have any heart devices, stents, or other chest implants, and no recent chest surgery or bleeding risks.
- You have not taken certain medications (like steroids, antibiotics, or mucolytics) recently, and you have no recent lung infections.

This trial tests if different types of vibration exercises can help people with COPD (a chronic lung disease). It may be a good fit if you have severe COPD or have had recent flare-ups, are not already exercising regularly, and are willing to try a new therapy.
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 looks at signals from non-invasive home ventilators to better track COPD. It may help understand how to manage the condition using data from your device.
This study collects leftover lung tissue or biopsy samples from surgeries or bronchoscopies to create a biobank for future research. It may help researchers understand lung diseases better, but you won't receive any direct treatment from participating.
This study tests a device that uses gentle vibrations on your chest to help move mucus out of your lungs. It is for hospitalized adults who have trouble coughing up phlegm due to pneumonia or similar infections.
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.
