" Not sure I understand the question but I have heard....the air that we breathe is actually a mixture of different gases.78% of air is Nitrogen while oxygen is about 21%. The other minor gases form only 1% of air. The ratio of oxygen in the air is actually good for us because anything above that would make the air more prone to oxidation. "

" I am thinking she is asking what your meter would read while on oxygen, and if you were not on oxygen what would the oximeter read just from room air.

That would probably depend on what your air quality is (smoking, dusty, ect) and your lung health, right?????

My best O2 reading while on oxygen goes from 98-99 and if I am just sitting and take off the cannula and check later, it might be 94-95. Both at rest, with no excessive activity like walking, exercising, ect...just sitting.
Hope this helps...

" Maddie, If I am just sitting on my butt quietly going about my business here on the computer, using 2.5 liters, my O2 level is 97-98.

If I amp up my level of activity to something other than just sitting on my butt, my level will drop as low as 89-90 depending on my level of activity.

If I am not wise and try to do any activities not using my oxygen support my level drops to the low 80s quickly

I have been advised many times that you are pretty safe (using your word) if you keep your O2 level at least at the 90 pct range, anything below that you are beginning to seek trouble.

Please keep this in mind, and really talk to your Dr or health care provider, they will give you the best input as to where you should be.

Take care, Bill "

" I usually sit at 3.5 LPM and have an O2 reading at 94-95. Any activity drives it down. On room air I'm in the mid to low 80's.
Pure oxygen in and of itself is a corrosive. That being said the best you are going to get out of an average concentrator is an additional 4% per LPM. So in a perfect world (like using TTO) the oxygen mix would be 41.5%. Mixing using the nasal cannula as most of us do I'd guess 35% at best. My $0.02...

" After years of jamming knuckles and crunching fingers working construction, my readings vary up to 4% depending on what finger I use for the pulseox. I don't use an O2 concentrator and get 98% percent while at rest and 99% if I do some pursed lip breathing. Worst case when I'm doing anything strenuous has been 94% and very short of breath. "

" I'm not on oxygen yet, but just sitting around relaxing I'm at 95-97. If I get up to do anything it drops to 90. If I do anything strenuous like carrying in groceries or carrying a load of clothes, it drops to around 85. "

" IMHO if your SPO2 drops below 90%, you should be on O2. Fact is if it drops below 88%, you are harming yourself, damaging your organs...
