Shallow Breathing

MRep,
Don't think it's swelling, but after 2 broken noses, one operation for a deviated septum, and a very narrow right airway, it doesn't take much for the airway to be blocked. So, that may be what's happening. However, it lasts for a given amount of time, say 15-20 minutes and then shows a recovery to a more normal pattern. So, I don't know. Thanks for the suggestion.
