User questions & answers

Question:	Is there a way to turn off the annoying glow
Answer:	No...the light is necessary for the pulse oximetry to collect data. Keep the hand under blanket or sheet. Try putting the hand in a sock to reduce glow.
Question:	How this one is different from Wellue Oxylink? Which one is better
Answer:	This is a tough question to answer as it is so specific to your context. If you are looking for something basic (focused on o2 only) the oxylink is probably your best bet (1 min data resolution). If you want more data and more professional analysis of the data, then the o2 ring is much better (4 second data resolution). When it comes down to it, I think the added battery life on the oxylink makes this preferable for most casual users. Only those that want to have more data and review data daily would probably prefer the o2 ring, which I think costs a bit more. I honestly loved the o2 ring but the battery didn’t even last 12 hours. It is absolutely required to charge it right before you put it on, in my experience).
Question:	Is the battery replaceable
Answer:	No
Question:	How long does the battery last and how long does it take to fully charge it
Answer:	For the first 11 months my battery would last one night but not two so I had to charge it every day, usually not a problem. BUT, DO NOT BUY!!! After 11 months the battery life started quickly decreasing to less than 2 hours per night which is useless since the first 2 hours my O2 level is always great. WELLUE DID NOT HONOR THEIR 1 YEAR WARRANTY. I've argued for a month with them and will change this advice if they ever replace it. It was great when it worked, but unreliable for battery.

User questions & answers

Question:	can it detect if you had a nocturnal seizure
Answer:	I am not really sure. If tracking oxygen levels while you sleep and certain levels can be used to indicate a nocturnal seizure then i would not see why not. This question may be more for a medical professional.
Question:	Can this write blood o2 measurements into Apple health
Answer:	Yes. But the measurements imported from the oximeter by Apple Health are one-minute summaries of the data collected by the oximeter, as I understand it. In other words, the data collected by the oximeter is on a second-by-second basis. It's more "fine-grained" than the minute-by-minute approach that Apple Health allows for, so the oximeter data gets summarized into one-minute chunks for AH.
Question:	Does this unit have an alarm
Answer:	no
Question:	Can this system write my results into the apple health app (healthkit
Answer:	Yes. As noted above, the oximeter collects data second-by-second and gives you its results (via its own app) in those fine-grained increments. Apple Health only allows for data on a minute-by-minute basis, so the oximeter data gets summarized minute-by-minute when sent to Apple Health.

Answer:	I use Oscar to view data from my cpap, and import the data from this oximeter as well. You get a lot more info on Oscar than the app. Oscar is free, just search for oscar cpap and the open source download will show up. Once you have it setup, open your phone app and export the data file to your mac.
