> The technique had a technical name, “glossopharyngeal breathing”. You trap air in your mouth and throat cavity by flattening the tongue and opening the throat, as if you’re saying “ahh” for the doctor. With your mouth closed, the throat muscle pushes the air down past the vocal cords and into the lungs. Paul called it “frog-breathing”. So, to state it in computing terms, this wasn't a fix for not being able to breathe, it was a workaround. But it seems to have worked really well: at 40, he was "able to spend most of his day outside the machine that still kept him alive".
