What is the O2ring?


Wellue O2ring


O2Ring as a health monitor can continuously track oxygen levels and heart rate. It is an FDA-registered product that has medical-grade accuracy.

With O2Ring, you can monitor your sleep all night.

It will silently vibrate to remind you when detecting too low blood oxygen saturation or irregular heartbeats. Of course, you can customize the reminder.

Main Function of O2Ring

  • Continuously tracking oxygen levels and heart rate
  • Alarming for abnormalities by silent vibration
  • Generating sleep reports

Why is O2Ring said to be a star product for overnight oxygen saturation monitoring?



1. Continuous monitoring

Most pulse oximeters in the market have the ability to spot-check but don’t support continuous real-time monitoring.

O2Ring makes difference, with advanced technology, Wellue O2Ring records in 4-second intervals.

The reliability of its recording data has been approved by clinics and users. By the way, many users complained short battery life of O2Ring. There is a reason.

Since this ring-sized O2Ring is used to monitor sleep overnight, its power consumption is not low. Just like your phone, you have to charge it if you use it for a long time. PC software download 

2. Highly durable storage of data 

O2Ring with built-in memory can save readings for 10 hours.

Those saved recordings later can be analyzed to learn about your sleep. Once there is amiss, you can make an instant response.

Connect O2Ring to your phone via Bluetooth, then you can get a sleep report based on synchronized records.

This sleep report shows 8 detailed data with oxygen saturation, pulse rate, and body motions icons.

You can clearly understand your sleep data for all night at your fingertips. If there are any doubts about your sleep, just share this report with your doctor so as to help him know your situation quickly and make an accurate diagnosis, which saves time and money. 

4. Comfortable wearing experience 

Wearing experience is also considered when it comes to O2Ring special ring-shaped design.

The ring of Wellue O2Ring is made with rubbery silicone type of material, which is stretchy so that it can fit fingers in different sizes.(Suitable for all sizes for adult fingers)As we know, it’s terrible to choose rings with inaccurate sizes. O2Ring’s special design helps users make the purchasing decision easier.

Compared with others, how does O2Ring stand out?

A variety of people made a comparison between O2Ring and other brand oxygen monitors. We are proud to say that O2Ring is of great accuracy, though other products have the same function of sleep oxygen monitoring.

1. While general bracelet/watch style oximeters are measured by reflection, O2ring uses a transmissive (clinical measurement method), which is more accurate and more stable.

2. Some of the smart rings can also monitor heart rates and oxygen levels and are widely recommended for fitness.

In the case of sleep monitoring, as O2Ring records in 4-second intervals, its recordings are accurate enough to be generated detailed sleep reports.

Who uses the Wellue O2ring?

who use Wellue O2ring

If you have a night of bad sleep or need to improve your sleep, Wellue O2Ring is a nice tool.

  • Sleep Apnea
  • Snore
  • Pneumonia
  • Asthma
  • COPD
  • Pilots

Without treatment, sleep problems may increase the risk of heart attack, stroke, diabetes, heart failure, irregular heartbeat, obesity, and motor vehicle collisions.

Sleep apnea, also spelled sleep apnoea, is a sleep disorder in which pauses in breathing or periods of shallow breathing during sleep occur more often than normal. Each pause can last for a few seconds to a few minutes and they happen many times a night. In the most common form, this follows loud snoring. There may be a choking or snorting sound as breathing resumes. Because the disorder disrupts normal sleep, those affected may experience sleepiness or feel tired during the day. In children, it may cause hyperactivity or problems in school.

Sleep health is of great importance. It is very dangerous when too low oxygen levels occur during your sleep, so monitoring oxygen levels during sleep is necessary for patients with sleep apnea.

O2ring - Vibrations

Some users have those common questions as follows. If you also encounter these questions, read the following: 

  • Why does O2Ring silently vibrate? I hate being bothered during sleep. 
  • Why should I use O2Ring because the CPAP machine already provides many parameters for sleep apnea? 
  • Why choose O2Ring rather than fingertip pulse oximeter? 
  • Why not just do the sleep study

Question 1: Why does O2Ring silently vibrate?

When sleep apnea occurs, the O2ring vibration is a reminder that it’s time to replenish your oxygen.

The majority of Sleep APNEA, i.e. it occurs mostly, if not entirely when sleeping on your back.

When OSA occurs, O2Ring vibrates to remind you of the need for supplemental oxygen.

We have collected some feedback from real users. Let’s see what they said.

User I.

“I can now report that I have successfully used the O2 Ring to prompt me to turn onto my side, and over time, help train me to sleep on my side.”

User II.

“For me it essential because I go in sleep paralysis then it happens and I need external stimulation to help me to take a breath and wake up and depending what on monitor take medication or call my doctor 911 if needed and I can provide recordings of all events.”

User III.

“It effectively controls my sleep apnea. I set the O2alarm to wake me when O2 drops. I am able to half wake up, take a few quick breaths, and go back to sleep after turning over where I can breathe properly. As time goes on I am better and better at staying on my side or stomach and often sleep through the night with no alarms. Also as time goes on I “raise the bar” in settings so it takes less of an O2 drop to trigger an alarm.No one paid me to say this.”

But there are still some users that don’t like to be bothered during sleep by its vibration. The vibrating reminder can be shut off of course. We are very happy that our product O2Ring can help so many people and hope they can keep healthy.

Question 2: With CPAP, do I still need to use O2ring?

CPAP is used to treat respiratory problems and O2Ring is used to track and record oxygen levels. Thus using O2Ring to monitor your treatment results is a nice choice. 

User VI.

Your CPAP can work fine and you can still drop to hypoxic levels in your sleep. this can be used to determine if you should talk with your pulmonologist about an oxygen concentrator.

User VII.

I was diagnosed moderate sleep apnea and they wanted me to use a CPAP. I wanted to explore every option and found this. Been wearing it good 2 months now and LOVE it! I’m actually finding the positions in which my oxygen goes down and trying to avoid those positions and retrain myself. This would even be good for non sleep monitoring.

User VIII.

Pairing this ring with the use of a cpap could be useful. Could indicate whether/not cpap should be adjusted, and could be another level of confirmation regarding interruptions while capa is in use.

User IX.

But if this keeps waking you up when your O2 level drops, are you getting restful sleep? This doesn’t correct the problem, just makes you aware you have one. You still need to use a Cpap machine.

User X.

O2ring with CPAP

User XI.

this ring was a great place to start with getting a referral. Just started CPAP. Went from over 60 or so events an hour to less than 1. Look at these pictures. One is wearing the ring before CPAP and the second is with CPAP. Just started a few days ago and I’m so glad I got help.

User Feedback

Question 3: Why choose O2Ring rather than fingertip pulse oximeter?

Fingertip pulse oximeters only have the ability to spot check, but O2Ring can do home continuous check. Continuous monitoring can make your recordings more accurate. Years ago people have to go to the hospital to do continuous oxygen level monitoring. But during the epidemic, crowded people will increase the risk of illness. Thus using O2Ring at home to monitor your oxygen levels is a better choice. User XII.

Question 4: Why not just do the sleep study?

It costs a lot of money and time to go to the hospital. Patients have to wait a long time in the process of making appointments with doctors and getting permission to do the sleep study. It is not good for health as time is life.

One of the most important reports is “History”.

After we have worn it for a period of time, we take the O2ring off and then the app automatically records the data while we are wearing it.

We can click on the report for a certain period of time and then view the details of it.

The following data are included in this report. (Analysis & trend graphs are automatically generated in the data table.)

1. Recording Time

2. <90% Time – How long has your blood oxygen been below 90%

3. Drops over 4% – Number of 4% drop in blood oxygen

4. Drops per Hour – Average number of oxygen levels drops over 4% per hour

5. Average SpO2

6. Lowest SpO2

7. O2 Score – It combines frequency duration and depth of oxygen drops. If O2ring Score turns to yellow or red, please ask your doctor for advice.

8. Average PR – The average number of heartbeats per minute. The chart on the computer looks like this.

How O2ring can protect your health (True Reviews)

Story 1. How O2ring helps with sleep health.


I have been using this for about 6+ months now. Love it! So helpful for monitoring at night and during in home infusions. Its helps to wake up if O2 or HR goes out of normal levels, it vibrate.

And forme it essential because I go in sleep paralysis then it happens and I need external stimulation to help me to take a breath and wake up and depending what on monitor take medication or call my doctor 911 if needed and I can provide recordings of all events.

To me its absolutely essential !

One thing is I wish it would have ability send recordings in differen format, so doctor would be able open in details all 10-12 hours of recording by himself, right now if I want send detailed information with second by second changes it has to be enlarged in that event and it will save it it PDF fime.

As well it would be wonderful and very helpful to provide not only over all O2 and HR information but show hiest in lowest numbers especially in HR as well in O2.

It’s all operated by app, so hopefully if company will make this little additions in app it would be even much better and more helpful!

I am absolutely recommend it to anyone who have any problems with heart or lungs and need monitoring, it’s easy, its light, its comfortable.

It is very simple to setup, it’s transfer data by itself automatically. Definitely best monitor over all I had in the past ! 

Story 2. How O2ring helps pilots.


Here’s the thing when it comes to flying with it.

Number one is that being a ring instead of a fingertip sensor, it doesn’t get in the way of pushing buttons, flipping switches, manipulating touchscreens, or “flying with two fingers” like you’re supposed to.

What I found is that I wasn’t wearing my fingertip one but instead putting it on every 20-30 minutes at fuel tank switch time to check my O2 level.

But as I found out on a recent trip back from TX at 15,500 and on O2, my tank had run out between checks and I had gone from 94% 20 minutes prior to 77%! It was only then I realized my tank was empty, and immediately descended 4,000’.

With the O2 ring, you can set an alert level (at say…88% or 90% for example) and if it detects that level, the ring vibrates to warn you.

Since you’re wearing it the whole time, the time between 02 drop and notification is virtually instantaneous, allowing you precious extra minutes to get back down—especially if you’re up in the flight levels.

Bottom line is I’m very happy with it so far. The secondary bonus for me is the recording for sleep analysis. Good product.
