O2 Score is a measure of oxygen shortage during whole sleep. It combines frequency, duration, and depth of oxygen drops. A higher score means oxygen is richer. If it's yellow or red, please ask your doctor for advice.

What Professionals Are Saying
Dr. Adam J. Story, DC
"You can use this to show your doctor how you're sleeping at night. That's the real benefit of this. This could actually in theory save your life, because if you don't know if you're losing oxygen in the middle of the night, you may be totally unaware that you may have sleep apnea. And this type of product can alert you to consult your own physician and find out if you actually have a problem."
Review on Mar.27.2022
Cajun Koi Academy
"Another reason why the alarm is so useful is that some people who sleep on their back or get into really deep snoring, especially if you have sleep apnea can drop their oxygen levels low, and so you can set the ring to vibrate and wake you up to remind you to re-adjust your position in your sleep. You can re-adjust and then slip right back into sleep and hopefully not wake up your partner as well."

What Our Customers Are Saying
Steven Griff
Highly recommended
"After spending 3 weeks in the hospital with Covid, after release and home on O2 ring has proven to be a great asset sleeping at night the downloaded graph in the morning provides me with a wealth of information. Now it will wake me when or if my oxygen level drops below a preset warning."
Pankaj Srivastava
The One Gadget that you need today
"I am Pankaj Srivastava, a fitness and health enthusiast for which I was suggested by the doctors of Clinicspots before going on the trek to Kedarnath and while traveling to high altitude regions; to use O2ring wearable pulse oximeter by Wellue for keeping track of my blood oxygen levels, through the monitor in my device which was portable everywhere, and the ring which is very comfortable to wear even at my office and during my exercise. It has helped me not only in tracking my levels but also help me storing the data on my devices and also helped me to know when my oxygen levels have fallen or are high. I would highly recommend this oximeter if you are traveling too because of its battery life and comfort. It can also be used by the elderly which can help you to track their blood oxygen levels, heart rate, and body movements. Wonderful Initiative by Wellue especially for people like me."
Ron G.
Exactly what I wanted
"I'm a pilot and wanted to get an oximeter to replace my aging finger clip-style oximeter. A couple of features I really like are the vibrating alarm, which I set to high when flying to alert me before hypoxia sets in. And then also - no more batteries to replace. My old unit required a CR2 battery, but this unit lasts longer than I can fly in a day, and then some. I noted that it tracks my oxygen well as I climb to altitude in my unpressurized airplane and had a little fun experimenting with adjusting my oxygen bottle feed at 12,500' MSL from 90% to 98% blood O2 level.
It appears to be very good quality and does exactly what I need it to. Compared to my old unit, my O2 readings are identical, so either they're both off or both accurate, but the readings seem reasonable and consistent and the heart rate sensor matches my Polaris HR belt, so that checks..."
Benjie
So happy to have bought one
"As part of my COVID-19 recovery, I need to monitor my O2 & PR as much as possible. O2Ring gave me that option plus some. The Reports were a big plus to my needs. As well as the alarm feature. I just wished it could be used in the shower and also use it while charging so I could gather a complete 24hrs stat of my system. I recommend this product for post-Covid patients still having O2 stability concerns and for Sleep Apnea patients to learn more about their illness."
Kenechi Munonyedi
A very handy and informative gadget, very useful
"Post- COVID and in the recovery phase, I needed to keep an eye on Oxygen Saturation levels and Heart Rate. That's where the O2 ring comes in. It's very useful to know how these levels change with different tasks and the mobile and desktop apps provide a lot of information and trends. Customer Service has been responsive and helpful. I would highly recommend it."
Barb
Amazing device, better than expected!
"I sleep on my back because of other medical issues and I snore, so my results weren't quite as good as I'd hoped but they are improving. The app report for each use is very informative, detailed, and visually well done. The graphs are very easy to expand and view even for short time periods. The pdf reports are also well done, easy to make notations on, and a wonderful record of my O2 status each night and over time.
The ring is very comfortable to wear. I wear it on my index finger and haven't had any issues with it catching on the sheets or any other problems.
The O2Ring was a little more than I was initially looking for, but I am very happy that I bought it because it provides a lot more information about my health status when sleeping. All pros and no cons after nearly a month of nightly use."
Mark Secord
Great product--and the company stands behind it.
"We bought an O2 ring about 8 months ago and have used it frequently to monitor my wife's SO2 levels--day and night. Having the graphs showing results over time is very helpful. She has been prescribed oxygen at night but it's inconvenient often and we wanted to get data on how much SO2 levels drop. The ring provides perfect data for assessing this, as well as how she does when she exerts herself during exercise during the day. We've shared data with her pulmonologist and he's impressed.
Several weeks ago the display on the device went dark. Wellue responded to my email inquiry promptly and had me do some interventions. When these failed to work they sent me a new O2 ring. Minimal hassle.
I don't give 5-star ratings easily but this one was easy."

"So the great thing about this product is you can now see it on your phone and record this. You can see now my oxygen saturation is 97 my pulse is 53. And so you can use this to show your doctor how you're sleeping at night. That's the real benefit of this. This could actually in theory save your life, because if you don't know if you're losing oxygen in the middle of the night, you may be totally unaware that you may have sleep apnea.

You can also adjust the vibration strength anywhere from very low to very strong. I love this feature because you can set it so that I'll barely wake you up. You can re-adjust and then slip right back into sleep and hopefully not wake up your partner as well."
Review on Jan.4.2020
Chigz Tech Reviews
"This product is FDA listed so that means it's medical grade, and uses the same transmissive oxymetry technology which is trusted by hospitals and clinics. This ring will benefit those with asthma, pneumonia, COPD, snoring and sleep apnea. Now once you're sleeping if there is any abnormalities detected in your breathing or heart rate, you will immediately be alerted with a silent vibration alarm allowing you to then change your sleeping position, so effectively improving your sleep quality and helping you with these sleep associated disorders."

What Professionals Are Saying
Dr. Adam J. Story, DC
"You can use this to show your doctor how you're sleeping at night. That's the real benefit of this. This could actually in theory save your life, because if you don't know if you're losing oxygen in the middle of the night, you may be totally unaware that you may have sleep apnea. And this type of product can alert you to consult your own physician and find out if you actually have a problem."

"Another reason why the alarm is so useful is that some people who sleep on their back or get into really deep snoring, especially if you have sleep apnea can drop their oxygen levels low, and so you can set the ring to vibrate and wake you up to remind you to re-adjust your position in your sleep. You can re-adjust and then slip right back into sleep and hopefully not wake up your partner as well. "

What Our Customers Are Saying
Steven Griff
Highly recommended
"After spending 3 weeks in the hospital with Covid, after release and home on O2 ring has proven to be a great asset sleeping at night the downloaded graph in the morning provides me with a wealth of information. Now it will wake me when or if my oxygen level drops below a preset warning."
Pankaj Srivastava
The One Gadget that you need today
"I am Pankaj Srivastava, a fitness and health enthusiast for which I was suggested by the doctors of Clinicspots before going on the trek to Kedarnath and while traveling to high altitude regions; to use O2ring wearable pulse oximeter by Wellue for keeping track of my blood oxygen levels, through the monitor in my device which was portable everywhere, and the ring which is very comfortable to wear even at my office and during my exercise. It has helped me not only in tracking my levels but also help me storing the data on my devices and also helped me to know when my oxygen levels have fallen or are high. I would highly recommend this oximeter if you are traveling too because of its battery life and comfort. It can also be used by the elderly which can help you to track their blood oxygen levels, heart rate, and body movements. Wonderful Initiative by Wellue especially for people like me."
Ron G.
Exactly what I wanted
"I'm a pilot and wanted to get an oximeter to replace my aging finger clip-style oximeter. A couple of features I really like are the vibrating alarm, which I set to high when flying to alert me before hypoxia sets in. And then also - no more batteries to replace. My old unit required a CR2 battery, but this unit lasts longer than I can fly in a day, and then some. I noted that it tracks my oxygen well as I climb to altitude in my unpressurized airplane and had a little fun experimenting with adjusting my oxygen bottle feed at 12,500' MSL from 90% to 98% blood O2 level.
It appears to be very good quality and does exactly what I need it to. Compared to my old unit, my O2 readings are identical, so either they're both off or both accurate, but the readings seem reasonable and consistent and the heart rate sensor matches my Polaris HR belt, so that checks..."
Benjie
So happy to have bought one
"As part of my COVID-19 recovery, I need to monitor my O2 & PR as much as possible. O2Ring gave me that option plus some. The Reports were a big plus to my needs. As well as the alarm feature. I just wished it could be used in the shower and also use it while charging so I could gather a complete 24hrs stat of my system. I recommend this product for post-Covid patients still having O2 stability concerns and for Sleep Apnea patients to learn more about their illness."
Kenechi Munonyedi
A very handy and informative gadget, very useful
"Post- COVID and in the recovery phase, I needed to keep an eye on Oxygen Saturation levels and Heart Rate. That's where the O2 ring comes in. It's very useful to know how these levels change with different tasks and the mobile and desktop apps provide a lot of information and trends. Customer Service has been responsive and helpful. I would highly recommend it."
Barb
Amazing device, better than expected!
"I sleep on my back because of other medical issues and I snore, so my results weren't quite as good as I'd hoped but they are improving. The app report for each use is very informative, detailed, and visually well done. The graphs are very easy to expand and view even for short time periods. The pdf reports are also well done, easy to make notations on, and a wonderful record of my O2 status each night and over time.
The ring is very comfortable to wear. I wear it on my index finger and haven't had any issues with it catching on the sheets or any other problems.
The O2Ring was a little more than I was initially looking for, but I am very happy that I bought it because it provides a lot more information about my health status when sleeping. All pros and no cons after nearly a month of nightly use."
Mark Secord
Great product--and the company stands behind it.
"We bought an O2 ring about 8 months ago and have used it frequently to monitor my wife's SO2 levels--day and night. Having the graphs showing results over time is very helpful. She has been prescribed oxygen at night but it's inconvenient often and we wanted to get data on how much SO2 levels drop. The ring provides perfect data for assessing this, as well as how she does when she exerts herself during exercise during the day. We've shared data with her pulmonologist and he's impressed.
Several weeks ago the display on the device went dark. Wellue responded to my email inquiry promptly and had me do some interventions. When these failed to work they sent me a new O2 ring. Minimal hassle.
I don't give 5-star ratings easily but this one was easy."
