Sorry for my annoying spelling, you may be aware I'm operating on limited sleep!
She has the nose one right now, only one night. She doesn't, as near as I can tell, have sleep apnea though. She had one issue all night on the study and I've never heard her have breathing problems. The bigger issue is her O2 sat drops and I don't think a sleep clinic is really the right place to deal with that issue, but I'm humouring this one... Anyway, it's all very complicated(you could write a medical journal on her issues) so we are trying this thing for now but I suspect a better solution would be sleeping with O2. Unfortunately their is very little research for her, so it'll be another round of specialists, I imagine.
