Ultrasound test of breathing muscle function in severe COPD flare
Part of Lungs & breathing clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are being admitted to the hospital mainly for a severe, sudden COPD worsening (exacerbation).
- You have COPD confirmed by standard medical criteria (GOLD)
- Recent lung tests in the last 5 years show airflow limitation (low ratio after bronchodilator and FEV1 under a set level).
- Your blood gas results do not show respiratory acidosis (your blood pH is not too low with high carbon dioxide).
- You do not already have a known diaphragm paralysis, and you can do the ultrasound breathing instructions (or are not on machines that prevent imaging).

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.
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 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.
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 looks at how the diaphragm (the main muscle you use to breathe) works during an emergency for people 75 and older who come in with sudden shortness of breath. It uses a simple ultrasound to check this muscle, which may help doctors understand breathing problems better.
