DO NOT use O2Ring. Use Iwearpulse
Hi folks
I have been trying everything including Oxygen supplementation as measured by the Getwellue O2 ring in an endeavor to get my oxygen levels to normal inspite using a Bipap. Please check below thread
https://www.apneaboard.com/forums/Thread...e-of-Bipap
After months of buying multiple machines, devices and the works I finally realized that it is the O2 ring that is inaccurate. The reasons are below -
* The O2 ring does not use the ideal portion of the finger and does not cover the entire finger and hence due to escaping light can result in a false reading (low perfusion index) based on your skin tone
* Instead I bought
https://iwearpulse.com/ and now with my Bipap it shows that my oxygen saturation is normal through the night. The wellue ring was misleading and incorrect
* I also bought 5 WatchPAT tests and they also have a oximeter that covers the whole finger offering a better perfusion index on measuring oxygen levels
* Note that the wellue O2 ring does give more accurate results for folks with fair skin that do not move a lot during the night but not for darker skin tones and with folks who move around a bunch
I would STRONGLY recommend everyone in this forum to stop using the O2 ring and instead use an oximeter that covers your fingertip instead of a ring

I am using the wearpulse too, it's a good unit so far.
RE: DO NOT use O2Ring. Use Iwearpulse
To be fair, all SpO
2 recording devices' accuracy are effected by skin pigment. It is logical since it is based on light traveling through the skin to determine a measurement. Here is a report from the NIH on this subject.

Aren't they all coming from the same Chinese Manufacturer?
I stopped using them once I figured out there is no way to turn of the Bluetooth signal when used during the night.
They will constantly emit EMF radiation, even if not connected to a device.
I got a pro grade pulse oximeter / spirometer for sleep analysis from an Italian Medical Device Company :
The MIR Spirodoc, which has a proper sensor and is therefore much more precise. You can view the sleep analysis results directly on screen or export it to a software suite, comparable to "O2 insight Pro".
RE: DO NOT use O2Ring. Use Iwearpulse
I've always been skeptical of the O2 ring as well, because of how how the sensor is designed.
Nobody else does that. Not Nonin, not Massimo, not Contec.
RE: DO NOT use O2Ring. Use Iwearpulse
Fingernail and toenail bed has traditionally been the most effective location. The other locations require an adjusted algorithm and use a reflective measurement not a measurement of the light passing through the evenly perfused nail bed.

In addition, I see so many HUGE security and privacy issues with the O2 ring, I can't vouch for it. In addition to it being inaccurate compared to my two other oximeter devices, your personal data is accessible by the company overseas (for goodness sakes, why?!?), the "custom" USB connector is somewhat concerning, and the company is unprofessional (see people's issues with returning ring in the product review section). I am surprised it's the default device for so many people.
RE: DO NOT use O2Ring. Use Iwearpulse
MVoltaire, looking at the device from MIR, could you tell me how the device actually attaches to you to monitor your O2 at night? I can't tell from the product picture.
RE: DO NOT use O2Ring. Use Iwearpulse
Is Iwearpulse Oscar compatible?
RE: DO NOT use O2Ring. Use Iwearpulse
I copied this gem of information down from a post by Red (Crimson Nape):
The most accurate finger to use for SPO2 is the right middle finger.
2nd best is the right thumb.
The right little finger produces less accurate results from the 2 already mentioned above.
Using the middle finger on the left hand gave the least accurate results.
So, which finger (or thumb) the sensor is placed on; and which hand is chosen can affect the results of SPO2 testing.
Before I had this information, when I performed my own personal SPO2 experiments in the past, I at least kept the sensor on the same finger for all of the tests.
