Interested in all the discussion about oxygen as I spent half today in A&E after going from SATs 92 at rest but 82/3 after minimal activity. I was asked about oxygen and when I said I had never had it suggested the dr said she would write to my GP about sorting something out. I had lots of tests but no acute problem found just the usual chronic problems. I hope something comes of it but now feel I have information to push for help. Having just moved house I am still trying to find the best doctor to see. So far 1 locum, nice but no authority and one very inexperienced one who couldn't interpret an ECG. Not encouraging!
