Newbie Nullus seeking advice

Change EPR from Ramp Only to Fulltime

Don't look at the lows, they only say to look deeper or not.  Look at the %O2 Durations, your <90% time: 3m:40s  bad enough to say watch it.

Your experiment sounds like a good one. But I wouldn’t describe your O2 as “pretty bad.” You had less than 4 minutes under 90, and the one low spike may well be a momentary loss of contact with the sensor.

Zero under 90 would obviously be better, but don’t worry too much about these readings.

I completely defer to Gideon’s “watch it.”

RE: Newbie Nullus seeking advice
What’s strange to me and why I don’t feel confident in this ring is because shortly after I got my machine I used the ring and this was my reading then.

Nothing has really changed over this short amount of time and my readings aren’t consistently that bad. 

What is the range for bad good better best for <90% time?

I’ve measured my sp02 throughout the whole day as well. I’m averaged 94-97% I would think if I had some underlying disease it would present itself through the day as well. I’m sort of convinced that the nasal mask probably isn’t the best for me. And I’ll try wearing the face mask tonight with the ring.

RE: Newbie Nullus seeking advice
woke up feel pretty good this morning. my mouth was dry so i think ill need to adjust the humidity a bit, but other than that i feel much better.


i changed epr to full time 


in concern of the sp02 levels. i changed the mask last night to the F30i and that alone reduced my numbers pretty significantly. ive aslo been drinking more than usual due to my girlfriends birthday celebrations which i personally believe is helping to attributing to the hypopneas

RE: Newbie Nullus seeking advice
O2 levels are usually lower during sleep than during the day. From a UCSF web site: "Everyone's oxygen levels in the blood are lower during sleep, due to a mildly reduced level of breathing. Also, some alveoli drop out of use during sleep."

Here's some information about O2 levels during sleep:

RE: Newbie Nullus seeking advice
had a hard time last night. little waves of anxiety for some reason, and horrible moisture problems in the tube. so i was getting up and taking the mask off to spin water out of the tube and go back to sleep so as you can see theres a few gaps.


i didnt drink any alcohol last night. and im a little surprised about the Sp02 levels. im going to buy a compatible device that works with oscar. 


my thought process is, if im maintaining 94-97% during the day. and im only getting these drops at night while i sleep without any sort of consistency it could be the ring and contacts.

Do adjust the temperature if you have a heated hose and/or use a fleece hose cover.

RE: Newbie Nullus seeking advice
I have been O2 all day. Your small desaturation is not a problem. I would watch it maybe once every 2 weeks but really you have dips in saturation that are not large but also short in duration.

My pulmonary Dr said lower than 88% for 2 to 3 minutes should be addressed- less not to worry about it. That was his suggestion 10 years ago. When he retired 3 years ago I specifically asked the new Dr and he told me the same thing.
