@lorifilipek Thank you for your summary of the article, It was a very confusing article.
Re the nebuliser, I use a Pari EFlow and it is fantastic, no tubes to clean and its fast, so easy to use and easy to take anywhere, It is more expensive than others but the convenience factor was important to me, you will also need a sterilizer to clean your nebuliser. I tried using the Aerobika but it did not work for me like the saline, but I know others that it has helped. Heather
