Quote:You seem to do things very methodically. Would you mind letting us know your conclusion about the best oximeter for OSCAR? I want to upgrade my one, but I do not have the time to read all the comments about the different models.
You might want to consider that the precision of the ring type is not the best. The clip on your nail must be considered for a realistic reading, though the ring type is okay for the tendencies.
FYI I purchased and received a Wellue O2Ring yesterday. I decided to stick w/ Wellue b/c it's compatible w/ Oscar, I believe it's compatible with SleepImage analysis (which my dentist uses and is a proprietary analysis of the data to produce Sleep Fragmentation data), and b/c some other users on the forum supported this brand. The SleepU doesn't alarm on heart rate, so that was out. (Actually, I mistakenly thought it didn't even track heart rate, but checking just now, it clearly does.) And, it was a toss-up between O2Ring and CheckMe. The CheckMe costs more and is bigger. So, I figured I'd go with convenience and price between the two.
I have not yet tried importing the data. I will do that later today or later this week. I'll let you know how that goes. I may have some difficulties here b/c I'm in daylight time (but my CPAP doesn't track that), so all my Oscar data is 1 hour off. I know others have had sync issues with this, but I'll find out soon enough.
Any questions, let me know.
RE: Help with treatment, questions, approach, understanding
Thanks for the update. I am waiting for your experience, and if it is positive, I will follow your lead.
RE: Help with treatment, questions, approach, understanding
G Szabo,
Here's an update regarding the O2Ring.
- The ring is easy to take on & off, so I find that convenient.
- It uses micro-USB instead of USB-C, and that just annoys me.
- It took a bit of time to figure out the best way to transfer files to my computer. Once I got my system down, it's easy.
- The O2Ring starts recording data exactly 2 minutes after putting it on. This is important.
- For me, the easiest way to sync the data is to:
- 1. Put the ring on at the same time that I start the CPAP
- 2. Manually rename the O2Ring binary file to 2 minutes after the CPAP start time
- 3. Note the CPAP start time is likely a bit off from real time. My CPAP is 5 minutes and 26 seconds in the future.
- Having done all this, I don't know if the data is useful! Yes, I see some drops, but none of them are currently serious. (I'm also on 1 lpm of O2.) If I had more serious drops, that would be important to know.
- I see some of the drops coincide with events but most don't.
- The ring has an optional alarm which you can set to go off if your O2 drops too low. I may play with this in the future.
- Right now, I don't see how the ring helps me change any of my behavior at this time. So, it's a neat toy but not particularly useful at the moment.
Any questions?

Thanks, UsuallyTired, for all the details,
I trust they will help others as well.
I hope you are doing better with your treatment. I believe the ring is a safety beacon to ensure everything is in order.
RE: Help with treatment, questions, approach, understanding
Thanks and you're welcome.
I'm writing the following partially b/c I want to share it but more so just get it off my chest and help process all the avenues I'm pursuing.
I continue to struggle with treatment, but I am making progress. Lately I've been trying a slew of masks and settings to see what works and doesn't.
I simply can't get pillows to work for me at anything above 6 pressure. I vent orally (with or without tape), and it wakes me up.
Over-the-nose FFMs don't work b/c I have to wear them relatively tight, and they tear up the bridge of my big nose. I've tried the AirTouch in two different sizes.
I'm working with the under-the-nose FFMs F30i and F40 currently. I particularly like how the F40 fits. However, both have had leak problems, but I think I'm making progress on good fits. I also have some oral venting at times which, though much better than with a nasal cushion, is still a bit uncomfortable.
I've been playing around with using a cervical collar, and I think that makes a huge difference.
Next I need to try some RemZsss liners to see if they help.
I also have a couple interesting doctors appointments coming up. One will give the results of a different home sleep study which, I was told, might give insight into UARS. We'll see. I seemed just like a normal study, but I'll await the interpretation of the doctor. I'm hoping he's more knowledgable than my current sleep doctor.
I am seeing a TMJ/jaw/airway specialist soon, and he will do a CBCT scan. He comes highly recommended, and I'm expecting his expert opinion on my airways -- both nasal and throat -- to see if that sheds light on treatment options.
From a previous opinion, I don't expect to need palatal expansion. But, I'm curious if this specialist recommends turbinate reduction (which an ENT has already recommended) or MMA (jaw advancement) or something else. I *hope* he doesn't recommend MMA. That is not something I want to go through or would be able to go through for a couple years.
Anyway... that's what's been going on.
RE: Help with treatment, questions, approach, understanding
Hi all,
I've been working on different settings of the past few weeks. My impression is that the higher pressure I go, the worse my charts look and more pressure is indicated. What is going on? This all seems to be working backwards.
Here is last night's chart, and I feel like absolute trash today.
At the beginning of all this, I was at CPAP 5 (EPR 0) and had better numbers.
Thanks
RE: Help with treatment, questions, approach, understanding
Looking through your posted APAP results, it is striking that the higher the EPR setting, the higher the flow limitations are, contrary to the general wisdom. Higher EPR usually reduces the flow limit if the pressure is correct.
The second thing is clear: according to the instrument APAP algorithm, you need higher pressure than your CPAP 5 cm pressure because you hit the 10 cm ceiling on June 25, the 9 cm ceiling on June 20, and the 12 cm ceiling on August 17.
I can think of the following alternatives.
1) Some people do not tolerate APAP. In such cases, you want to find the optimal CPAP pressure by manually setting the constant pressures and finding the best setting.
2) You should stay on EPR=0 or EPR=1 with APAP (and with CPAP, for that matter)
3) Your condition is changing and becoming worse.
I would suggest testing alternative 3) and using the CPAP setting of July 19. If its outcome is similar to the previous result, then you should not use APAP, and you should find your optimum CPAP pressure, which gives you the lowest flow limits at the EPR=0 condition. Once found, you can increase the EPR setting to reduce your flow limit further.
