Hi Bluesky,
Are you able to open this link from your comp.?
http://www.chestjournal.org/content/109/2/400.full.pdf
I found this many months ago when I was in the hopsital and it talks all about the tests used for people with MG who have breathing difficulties...At the time, I was able to access the full article, but I'm having some comp. issues right now and it wont let me open it...
It mainly talks about people who have upper airway obstruction that might not be easilly detected through the standard testing, and offers better tests to gather info. on true weakness when it comes to respiration...It was very helpful, but I can't open it now! lol...I hope that you're able to open it, and it's helpful!
