Hoping to prevent someones exacerbation

I would simply like to alert all COPD patients on oxygen to please be aware that 88- 92% means just that. For years we have been shooting for the highest sat possible, not realizing that in doing so, there is a real risk
of hypercapnia, too much carbon dioxide. The doctors have said nothing, the oxygen people have said nothing, I am so angry. There should be a simple sticker on every oxygen machine. There are so many peo having
mortal ER visits and still they say nada. I am not trying to take the place of anyone's doctor. But we still would not know if we didn't happen to look it up. Look up hypercapnia, the symptoms etc. It could very well save your life .Especially if you are getting an oxygen saturation of over 92% . Waking up in the middle of the night with a diff personality, or disoriented. Waking up in the morning almost having to have an ambulance come out. Just research the dangers of too high oxygen saturation, please. Thanks.
