Ultrasound might reveal hidden lung damage in COPD

This study is testing whether a simple lung ultrasound can tell the difference between a sudden COPD flare-up and stable disease. It will compare ultrasound images, breathing tests, and exercise ability in about 60 people—those with an acute exacerbation, those with stable COPD, and healthy controls. The goal is to see if ultrasound findings, like B-lines and consolidations, relate to how breathless patients feel and how well they can move. If it works, lung ultrasound could become a quick, non-invasive way to check disease severity at the bedside.
