thanks for this info. i did read the article. it makes a lot of sense, but for my particular situation ----after a thousand hours of dialog with my AI docs and my three neurologist-----and numerous physical exams on just about every major organ of my body to include countless blood and even spinal fluid test-----all of us are in general agreement that my particular "type" of what many call sighing dyspnea was initiate by something that we will probably never figure out. but agree it is some form of dysautonomia of my nervous system----more specifically the balance between the sympathetic and parasympathetic systems with particular involvement of the vagus nerve. it is my opinion that so much of the medical advice you see on the internet about signing dyspnea as an issue of the mechanics of their breathing beathing techniques, carbon dioxide intolerance, speech re-training, anxiety reduction---and on and on-----are way off base and represent legacy medical beliefs. may be true for some----or even many-----but miss the mark totally for so many others----like me.
