Read our COPD research guide →This study is testing whether endobronchial valves — small one-way valves placed in your airways during a bronchoscopy — make everyday activities easier by measuring the physical effort your body uses during those activities. Researchers want to understand not just whether you *feel* better after the procedure, but whether your body is actually working less hard when you do things like climbing stairs or getting dressed.
People with severe emphysema struggle with everyday tasks, and while patients report feeling better after this treatment, doctors have never actually measured the physical load your body experiences during these daily activities. This study aims to prove scientifically that the treatment truly makes these activities less exhausting.

You will undergo the standard lung valve procedure as planned. During your regular follow-up visits, you will be asked to perform some everyday activities — like walking or climbing stairs — while wearing a portable device that measures how much oxygen your body is using. These measurements will be taken before your procedure and again 6 months afterward to see if the treatment has reduced the physical effort required for your daily tasks.
