Different inhalation volumes in COPD bronchodilator test
Part of Injuries & trauma, Lungs & breathing clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are older than 40.
- You have a smoking history of at least 10 pack-years (for example, one pack a day for 10 years).
- Your lung function (measured by a test called FEV1) is 70% or less of normal after using a bronchodilator.
- Your doctor has said you need a bronchodilator test — a test that checks how well your airways open after using an inhaler.
- You do not have asthma or other chronic lung diseases like pulmonary fibrosis.
- You do not have uncontrolled heart problems, are not pregnant, can perform breathing tests, and are not allergic to the study drug (salbutamol).

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 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.
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 looks at different lung immune cell patterns and how they work in smokers who are not yet diagnosed with COPD or asthma. It may help researchers understand why some people are more likely to develop COPD, which could guide future prevention or early treatments.
This study looks at lung function in people with early COPD (chronic obstructive pulmonary disease) to understand what happens over time. If you meet the lung test and health requirements, you may be able to help researchers learn how to better track and manage early COPD.
This trial tests a portable device that delivers gentle air pressure to help you breathe easier. It is for people with severe COPD (chronic obstructive pulmonary disease) who want to see if this device can improve their breathing and daily life.
