This study tests whether using a breathing muscle training device, along with standard physical therapy, helps people recover more quickly after a lung transplant. About 90 adults waiting for a lung transplant will take part. The goal is to see if this training improves breathing…

This study looks at how changing the pressure inside a breathing machine affects lung function in 20 patients with obstructive airway diseases who are on full ventilator support. Researchers will test different pressure levels to see how they impact gas exchange and how the lungs…

This study is testing whether a breathing test called the lung clearance index (LCI) can detect small airways disease in adults with chronic lung conditions like asthma or fibrosis. Researchers will compare results from 300 patients with lung disease to 300 healthy volunteers. Th…

This study aims to see if a simple, non-invasive breathing test can accurately measure the acidity (pH) in the airways, which is often abnormal in lung diseases. Researchers will compare results from this breath test with standard methods in 150 healthy volunteers and people with…

This study watches 200 people with lung, gut, or hormone diseases over time using special brain scans (PET). It aims to see how these diseases change brain activity and whether those changes can predict tumor return, spread, or survival. No new treatment is tested—just observatio…
