COPD

Hi. Thank you for posting. Are you referring to your oxygen saturation, which is obtained by a pulse oximeter -- such as is described in this post (https://copd.net/clinical/home-pulse-oximeter-monitoring)? If so, normal oxygen saturation is 98%, although acceptable for you goes all the way down to 90%. And, for some people with COPD, 88% is acceptable -- and learning what is acceptable for you can be determined by talking with your COPD doctor. We have an article on this that I will post here if you are interested (https://copd.net/clinical/interpreting-oxygen-levels). There are also various things that may cause this "oxygen saturatoin" to get lower than 88%. Probably the most common is an inaccurate reading, which may happen in such situations as your fingertips being cold. Before I continue here, is this what you are referring to?

I'm one of those people that John Bottrell spoke of my O2 level is 88%. I have noticed that my O2 levels drop out when I'm active. I find myself having to stop and take a break, when I do my levels come back up to my acceptable level. I also agree with John to read the articles that he suggested, I think they may help.
