Quality of life study for DDB with OPEP device
Part of Lungs & breathing clinical trials.
This study looks at how a breathing device called OPEP affects the quality of life of people with DDB (a lung condition that causes widening and damage to the airways). If you or your child has DDB and doesn't already use an OPEP device, this trial may help understand if starting one improves daily life.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be at least 8 years old (children 8–17 or adults 18+ are welcome).
- You have been diagnosed with DDB (a chronic lung condition).
- You do not currently use an oscillating positive expiratory pressure (OPEP) device.
- Your DDB symptoms are stable (not in a sudden flare-up).
- You attend regular follow-up appointments with your doctor.
- You do not have other serious or uncontrolled health issues that would interfere with the study.

This trial tests a home-use device called BiWaze Clear, which helps clear mucus from your lungs. It is for people with bronchiectasis (including those with cystic fibrosis) who have had recent lung infections and can use the device at home.
This study compares two breathing techniques—a set of active cycle of breathing exercises (ACBT) and an Aerobika device—to see which helps people with bronchiectasis clear mucus better and have fewer lung infections. You may be eligible if you have frequent flare-ups and have not used the Aerobika device before.
This study checks how sleep and overall quality of life change for children who use non-invasive breathing support at home. It also uses questionnaires to understand what helps or harms sleep and daily comfort so families and care teams can improve support.
This trial tests a fun interactive game and device to help children with bronchiectasis improve their breathing and lung health. It is designed for children who are stable and have not had recent infections or treatments.
This study looks closely at why children feel short of breath (“dyspnea”) and how breathing symptoms change over time. Your child may help doctors improve understanding and care for breathing problems like asthma or other lung conditions.
This trial tests a device that briefly opens your airways to help release trapped air after exercise. It may reduce shortness of breath and improve your daily life with COPD.
