Diaphragm breathing test to find air trapping on a ventilator
This study looks at a new way to check if air is getting trapped in your lungs while on a ventilator, using ultrasound of your diaphragm. If it works, doctors could adjust your ventilator settings more precisely to help you breathe easier and come off the machine sooner.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older
- You are currently on a breathing machine (ventilator) in a 'pressure support' mode
- You are at risk of air trapping in the lungs or having trouble coming off the ventilator
- You already have a small tube with a balloon in your food pipe to measure pressures
- You are not pregnant, have no esophageal diseases (like varices or narrowing), and are not too unstable
- You consent to the study

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 study compares two ways to measure how well a baby’s diaphragm (main breathing muscle) works in babies and children who need breathing support. It may help doctors choose the best test to guide safe breathing changes, like when to remove the breathing tube or support.
This study tests a way to train the diaphragm (the main breathing muscle) using ultrasound guidance to help people on breathing machines get stronger. It may help patients who are on a ventilator recover their breathing ability more effectively.
This study uses ultrasound to look at how well your diaphragm (the main breathing muscle) is working while you are on a breathing machine. The goal is to see if this can help doctors predict when you can safely breathe on your own and leave the ventilator sooner.
This trial tests a personalized pacing device that uses ultrasound to help your diaphragm muscle work better while you are on a breathing machine. It may help you breathe on your own sooner and improve your recovery.
