Have you had bronchoscopic lung volume reduction?

I have severe COPD for about 8 years. I use O2 at night. I still work my job of over 10 hours a day. I am running out of air so much of the day. My pulmonologist is having me do blood gas this week and check if I would be eligible for bronchoscopic lung volume reduction. What was your experience with this? Was it successful? How much down time did you have? Was it worth it to do it|? If it was worth it, how long ago did you do it and how is it now? Do you still use O2 at all? Any info is much appreciated!
