Ultrasound to check diaphragm muscle during breathing trials
Part of Lungs & breathing clinical trials.
This study uses ultrasound to look at how your diaphragm (the main breathing muscle) moves while you are being taken off the breathing machine. The goal is to see if ultrasound can predict if you are ready to breathe on your own.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older
- You are currently on a breathing machine or have a trach tube to help you breathe
- Your doctor has decided you are ready to try breathing without the machine (called a 'spontaneous breathing trial')
- You cannot have known nerve damage to the diaphragm, a pre-existing muscle or nerve disease, or a spinal injury above the neck level
- You cannot have had muscle relaxants (paralytics) in the last 24 hours
- Your body mass index (BMI) must be 40 or lower, and you cannot be pregnant or breastfeeding

This study uses a special ultrasound technique to look at how your diaphragm (the main breathing muscle) moves while you try breathing on your own. It may help doctors better understand when patients are ready to come off the breathing machine.
This study uses an ultrasound to measure how well your diaphragm (the main breathing muscle) moves during a breathing test, to see if it can predict whether you will be able to breathe on your own without the ventilator. This could help doctors decide the best time to take you off the breathing machine.
This trial measures how your breathing muscles work while we try taking you off the breathing machine. The results could help doctors predict when you're ready to breathe on your own.
This trial tests if using ultrasound to monitor your heart during a breathing test can help predict if you will need the breathing tube again. It is for people on a ventilator for at least 24 hours who are at higher risk of needing the tube reinserted.
This study uses ultrasound to measure how well the diaphragm moves in patients who are breathing with or without a breathing tube. It may help doctors better understand breathing function and guide treatment.
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.
