Hi again, sharonr - great question! Are you being considered for this procedure? It's only natural to want to know more about it! Fortunately, we do have some material published, right here on COPD.net, which focuses on the endobronchial procedure. In fact, some of our community members have spoken about the procedure from their own personal experience.
For your convenience, here is a link to several of these articles: https://copd.net/search?s=endobronchial%20valve%20Zephyr. I do hope you find them to be helpful in a practical way.
Wishing you well,
