I think this is an important subject that hasn't been picked up because it was started on another thread with a different subject ( viewtopic.php?t=838)
According to http://www.sleepnet.com/apnea/bestof/113.html supplemental oxygen is given to people whose Oxygen Saturation is 88-90% at rest.
They state:
Pulse Oximetry- a non-invasive measure of one's oxygen saturation; that is the amount of oxygen saturated in the hemoglobin in terms of percentage. This is not as accurate as the values obtained from an arterial blood gases (ABG) test and should only be used as a gauge of oxygenation. Normal ranges are between 95-100%. Supplemental oxygen is not generally instituted unless Sa02 is less that 88-90% at rest.
I am not exactly sure if "at rest" means simply awake and resting or if that includes while asleep.
I am curious what the experiences of CPAPTALK readers has been with regards to receiving supplemental Oxygen along with their CPAP treatment.
Anybody here using it ?
Why did your Dr. prescribe it ?
Did you find CPAP treatment was not effective until the oxygen was added ?
Thanks

Oxygen Levels
Hugh,
The tech. who oversaw my sleep study came in just over an hour after I "fell asleep" and said my oxygen level dropped to 82%. She said that I had OSA and didn't want my oxygen level to get a lower so she put me on the CPAP to find my pressure. She kept bumping up the pressure until my oxygen level returned. I am at 14 but snore in my FF mask sometimes and am more tired than before I started treatment 2 1/2 months ago. There was never any mention about adding O2.

Re: Did your Oxygen Saturation go below 88% / Oxygen Users
My sat's were consistenly in the 70's% so that's no joke. Nothing ever mentioned about O2 supplementing. I'm going to buy the software for my 420E. I asked for it, but the DME/RT is coming on Fri. If she doesnt have it, CPAP.com, you'll have an order PDQ.
My sat's were back up in the 90's% for the titration study. So that proved the CPAP titr. study helped. I'm still tired. I can wait to see if this makes me energized, dragging thru day now.
sleep is a joke, fragmented all nigh long.

oxygen level
During my sleep study, my oxygen level dropped to 55% without the bipap. However, when I used the bipap, my oxygen level rose to 92%, making supplemental O2 unnecessary.
Problem is, I do not tolerate the bipap for long at night so my g.p. prescribed oxygen for when I'm sleeping without the bipap. I haven't used the oxygen though, because I can't afford it ($350 / month rental on that machine). I believe a "passive" oxygen supply would be a waste of money. considering the fact that I average 115 episodes of apnea per hour.

I started on O2 just at night with my CPAP.
My O2 sats dropped to 77 during the night.
Now I am on O2 all the time. It has made a dramatic difference in my life.
I have to thank my MIL for my being on O2 and feeling so much better.
She lives with us and is also on O2. Our O2 provider (Lincare) was here
over time and noticed how short of breath I was. She told me to get this checked out.
It is expensive but it makes a HUGE difference in my life!

My O2 level dropped to 59% during the sleep study but my baseline "awake" O2 was 98% -- in other words I'm fine when I'm awake. I don't know what my figures were when on CPAP, but my doctor didn't prescribe O2, so the CPAP must have been enough to bring the levels up.

Hi Hugh,
I think what they are referring to as far as oxygen level at rest is:
the constant oxygen saturation level that you normally have when not performing any physical activity. I think it refers to a constant level of oxygen saturation as opposed to the temporary decrease in oxygen saturation that you get when you are apneic. I think supplemental oxygen is added when oxygen saturation does not go above 88-90% when a cpap is being used properly or if a person has an underlying need for oxygen such as emphysema or pneumonia or something of that nature.
I'll bet that's as clear as mud!
Hope this helps

o2?
in my sleep tests, my oxygen was down to 59, but went no higher than 90, at anytime during the night. on cpap, i was told things were much improved, dont know how much though, but will certainly ask when i go back for my review. i've learnt a lot reading these posts on here, enough to have the confidence to ask when i go back, & understand a little more about whats going on, & why. jean
