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 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 trial is testing how well a simple ultrasound can measure diaphragm (breathing muscle) function in people with COPD who are using a breathing mask (non-invasive ventilation). The goal is to see if this measurement can predict how well someone will recover from a COPD flare-up.
This trial uses ultrasound to check how your diaphragm (the muscle that helps you breathe) is working while you are on a ventilator. The goal is to help doctors set the breathing machine more accurately to make it easier for you to breathe on your own.
This trial tests if using an ultrasound to look at the diaphragm can help doctors decide when to take COPD patients off a breathing machine. It may help make weaning safer and more successful.
