Ultrasound of chest muscles to measure breathing effort
Part of Lungs & breathing clinical trials.
This study uses a special ultrasound (like a painless sound wave test) on the muscles between your ribs to see how hard your breathing muscles work. It aims to find a simpler way to check breathing effort in people with COPD and in healthy volunteers.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be either a healthy adult or have moderate-to-severe COPD (stages 3-4).
- You cannot have a BMI over 35.
- You cannot be pregnant or breastfeeding.
- You must not have had a recent COPD flare-up in the last 6 weeks.
- You cannot use more than 2 liters of extra oxygen per minute during activity.
- You must not have certain chest or muscle conditions or recent surgeries that might affect the test area.

Other trials that look related to this one.
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 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 compares breathing tests, ultrasound of the diaphragm, and muscle mass in healthy people and people with stable COPD. It aims to better understand how COPD affects the diaphragm and overall muscle health.
This study compares a lung ultrasound method (shear-wave elastography) with breathing function tests to see how well they match. It may help researchers better understand how to measure lung health using imaging versus breathing tests.
This study uses ultrasound to measure how stiff your diaphragm muscle is while you breathe. It aims to find out if this ultrasound measurement relates to the pressure your diaphragm generates, which could help understand breathing muscle function.
This study uses an ultrasound to measure how well a chest muscle moves when you try to breathe on your own. It may help doctors decide if you are ready to come off the breathing machine.
