@spider109 Hi! I can't speak for what any pulmonary nurse says but I have a feeling the nurses sent out to train us on our SmartVest may not have much experience with bronchiectasis. My training nurse was great getting me started but also said the vest could replace other tools in a few weeks. Definitely do not try to make it replace saline nebulizing!
Everyone is different but I found the vest helped get up for phlegm right away. I experimented and ended up with the most helpful routine being to nebulizer saline while using the vest and huff coughing on the vest breaks. I did stop the aerobika which had been doing nothing for me. I did run this by my doctors who approved.
