Ultrasound for diaphragm in COPD flare-ups
Part of Lungs & breathing clinical trials.
This study uses ultrasound to measure how well your diaphragm muscle works during a COPD flare-up. The goal is to see if this measurement can help predict how you will recover.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are hospitalized mainly because of a severe flare-up of your COPD (breathing trouble getting much worse than usual).
- You have had a lung function test (spirometry) within the last 5 years showing certain numbers: the ratio of FEV1 to FVC is below 0.70 and your FEV1 is less than 80% of what is expected for your age and height.
- You have smoked at least 10 pack-years (for example, one pack a day for 10 years, or two packs a day for 5 years).
- You do not have diagnosed diaphragm paralysis, and you can have an ultrasound (you are not on a breathing machine and can follow simple instructions).
- You are able and willing to give written permission (informed consent) and are not pregnant.

This trial studies how well your diaphragm (the main breathing muscle) works during a severe COPD flare, using an ultrasound scan. It may help doctors better assess breathing muscle performance when COPD symptoms suddenly worsen.
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.
This study looks at how COPD affects your breathing muscles and overall muscle health. It uses simple tests like breathing tests and ultrasound to see how your diaphragm (the main breathing muscle) is working, which may help doctors better understand and manage COPD.
This study uses a special ultrasound technique to look at how the diaphragm moves and works. It aims to see if this method can measure diaphragm strength in healthy adults, which might help doctors understand breathing issues better.
This trial uses ultrasound (a non-painful scanning method) to measure how well the diaphragm works around the time of surgery. It aims to learn whether diaphragm changes during surgery relate to breathing problems, especially in people undergoing abdominal, pelvic, or vascular operations.
This study tests whether using ultrasound (sound waves) to look at your diaphragm (the muscle that helps you breathe) can help doctors decide the right time to take you off a breathing machine. If you have COPD and are on a ventilator, this could help you get off the machine sooner and more safely.
