@cressida92 I don’t know if officially classified as therapeutic but from personal experience, during my bronchoscopies they have pulled out mucus plugs. The procedure itself, unless you are doing something more like a biopsy is only about 5-10 minutes. I’ve had quite a few done and for me not had any issues other than the residual typical side effects the day of (sore throat, possible headache depending on how well you tolerate anesthesia and chills). For me the worst part is waiting on the results as the cultures take a long time to grow.
