Effect of endobronchial valves on diaphragm movement in COPD patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates how the insertion of endobronchial valves affects diaphragm mobility in patients with chronic obstructive pulmonary disease (COPD) and emphysema. The study aims to determine if diaphragm movement improves post-treatment and whether this improvement correlates with enhanced symptoms, lung function, and physical ability. Additionally, it will explore if immediate ultrasound evaluations can predict clinical outcomes related to diaphragm function and atelectasis development.
