Hello, I am a 64 yr. old male in stage 3 COPD. I have been evaluated for zephyr valves but I was told that I do not qualify because I have " lateral Ventilation " which means that my bronchia's leak and zephyr valves would not close off the air to my bad lobes so there is no sense in doing the procedure. I was also told that this lateral ventilation may heal and therefore I may qualify at a later time. My question is if this lateral ventilation can heal how long would this take and also is the statement in fact true.
