Breathing device study for lung expansion and clearance
Part of Lungs & breathing clinical trials.
This study tests two breathing devices—one that uses positive pressure and one that uses high-frequency vibrations—to see which helps open up clogged or collapsed parts of the lung better. Electrical impedance tomography (EIT) is used to scan your lungs like a video while you breathe, to measure the results.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need to have a condition that requires help opening up your lungs or clearing mucus out of your airways, as decided by your doctor.
- You must agree to join the study and sign a consent form.
- Your blood oxygen level must be low—specifically, the ratio of oxygen in your blood to the amount of oxygen you breathe in should be less than 200.
- You need a score on the Airway Care Score (a measure of breathing problems) that is less than 7.
- You must be 18 years or older.
- You cannot have a pacemaker or defibrillator because the lung scanner (EIT) can't be used with them.
- If you are unstable—meaning your blood pressure is too low (systolic below 90 or mean below 60)—you cannot take part.

Other trials that look related to this one.
This study uses two lung imaging tests—CT scan and EIT (a non-invasive electrical test)—to find the best ventilator pressure for people with sudden breathing failure. The goal is to tailor settings to your lungs and potentially improve breathing support.
This trial tests a new airway clearance device in ICU patients with pneumonia. It may help clear mucus from your lungs and improve breathing without needing a breathing tube.
This study tests a way to set breathing machine pressures using electrical imaging of the lungs. It aims to find the best settings for patients with lung injury after trauma or major surgery, helping them breathe better with less damage.
This trial tests whether using electrical impedance tomography (EIT), a safe and non-invasive monitoring technique, helps doctors set the ventilator better for patients with low oxygen levels. It may improve your breathing support during mechanical ventilation.
This trial uses a special imaging technique (electrical impedance tomography) to find the best ventilator settings for patients with acute breathing failure. It may help doctors tailor treatment to improve lung function.
This study tests a new way to measure pressure in your lungs while you receive high-flow oxygen therapy. It may help doctors better understand how to use this treatment in people with heart failure who need extra breathing support.
