Thanks for your response Sue. I am not very good at finding old discussions (this one began in Jan 2019) so it iots of work for me to find my post and check for replies. I appreciate you finding it and responding.
Until the Oregon study is completed, we won't know for sure if saline actually kills bacteria in the lung as opposed to in a petri dish. I believe they are recruiting so it's really at an early stage. My doctor, and others, have said that it is not a treatment for killing bacteria. However, clearing sputum out of airways is certainly beneficial.
I am very glad that you are doing well. I believe it's a year since you stopped the antibiotics?
