Diaphragm dysfunction

This trial tests whether a newer ventilation method, called flow-controlled ventilation, keeps the lungs and diaphragm in better shape than the standard pressure-controlled method during elective heart bypass surgery. About 154 adults scheduled for on-pump coronary artery bypass …

This study looks at whether a special breathing exercise (threshold inspiratory muscle training) can make the diaphragm thicker and move better in people with stable COPD. Fifteen participants aged 40-59 with moderate COPD will do the training. The goal is to see if this exercise…

Researchers at Radboud University Medical Center are studying whether the diaphragm, the main breathing muscle, enters a hibernation-like state in ICU patients who need a breathing machine. The study follows 112 adults on invasive mechanical ventilation for at least three days. S…

This study checks if a special ultrasound technique (shear-wave elastography) can accurately measure diaphragm pressure without needles or tubes. Twelve healthy adults will perform breathing exercises while researchers compare ultrasound readings to standard pressure measurements…
