Testing in the 90s. On exertion or even walking if I feel slightly stressed low 80s. I stop and relax my breath as soon as I can then onward I go.

Thank you everyone. I wish I knew how to use this site better.

carl 2: You don't have to believe me; I was giving you answers based on my personal experience. My O2 sat levels, like everyone else's, depend on what I'm doing. When I'm at rest, without O2 in my chair, my sats are usually in the 95 range, assuming that I'm not sick. If I'm sick they can range anywhere from 80 to 95. If I'm up and moving, without O2, my sats can fall into the 70s if I maintain the activity. For people without lung disease, the differences aren't as great, but O2 saturation levels vary according to the level of effort.

it depends. If you have no lung disease, 97 to 99 would be normal. If you have lung disease, all bets are off. People have resting O2 levels from the 60s on up. At 60 you're probably pretty sick, but there are many many people with resting O2 saturations of less than 88 and most of them aren't even aware of it.

86-88%
