A Chinese-based medical company, Wellue, has developed a ring that can be worn on your index finger or thumb to continuously monitor not only blood oxygen levels but heart rate also. This product only weighs a slight 15 grams-which is no heavier than a DVD while its LED screen lights up with just a tap of your finger. The O2Ring displays the heart rate and oxygen saturation which can also be viewed via a smartphone app. This product is used by many with respiratory issues such as sleep apnea, asthma, COPD, and most recently those with Covid pneumonia. Reports can simply be downloaded for review and any necessary treatment. Notifications can be set to alert if levels drop below set levels. The device easily turns itself off once removed to preserve battery life.

REVIEW - Have you ever wanted to check your blood oxygen saturation levels (Sp02) because you have or think you might have sleep apnea or some other health issue. The Wellue O2Ring lets you do that quickly and will let you track oxygen levels and your heart rate while you sleep. Let's take a deep breath and check it out.

What is it?

The Wellue O2Ring is a wearable oximeter that records sp02 levels and heart rate every second, as well as body movements.

What is Sp02? Its oxygen saturation and is a measurement of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The body needs a certain level of oxygen in the blood or it will not function as efficiently. SpO2 (blood oxygen saturation levels) of a healthy person should be between 94% and 100%.

PULSE RATE RANGE - 30 to 250 bpm
MEASURE INTERVAL - 1 second
DISPLAY INTERVAL IN APP DATA CHART - 4 second
BUILT-IN MEMORY - 4 sessions, up to 10 hours for each session

Design and features

You've seen the oximeters at your doctor's office that clip on to the end of your index finger right? Well, the O2Ring does the same function, but it slips on your finger like a ring. A big ring. But don't worry, it has an expanding band so it should fit just about anyone.

The top of the O2Ring has a touch button and a display that toggles between showing the blood oxygen saturation level percentage, heart rate, and time of day.

Inside the band of the O2Ring is the oxygen and heart rate monitor and on one side of the ring is the micro USB charging port.

My thumb is glowing red! I feel like I'm a superhero!

Although the Wellue O2Ring is large, I found it to be comfortable to wear on my thumb all night long. After a minute or two I forgot I was wearing it and it didn't cut off the circulation or make my finger numb. The ring can also be worn on your pinkie or another finger.

The backlit display makes this wearable do double duty as a watch, so it's handy for checking the time in the middle of the night. Note that the display is only on for a few seconds before it automatically turns off. But you can tap the touch button to wake it up again.

The app

The Wellue app which I installed on my iPhone 11 Pro Max has a relatively easy to understand user interface that shows a dated time range for the recorded sessions, along with the O2 score for the session and the number of oxygen level drops. Session data is automatically synced with the app if the app is open and you remove the O2Ring from your finger.

You can see even more info by clicking on the session. From there you can see a graph of the session for Sp02 levels, heart rate, and motion. You can zoom in on the graph and you can even export the data to CSV file that you can share with your doctor.

Another feature of the app gives you a real-time view of your Sp02 level and heart rate.

In the settings section of the app, you can customize various settings like the vibration to notify you if your oxygen level drops too low or an abnormal heart rate is detected. You can also allow the data to be sent to Apple Health.

Battery life

The O2Ring's built-in rechargeable battery has 12-16 hours of battery life. I found that if I charged it before getting ready for bed, the charge would last the entire night and would only last part of the next night. So it's important to charge it each day so it will record your entire sleep session before running out of juice.

What I like

What I'd change

Better battery life would be nice so you don't have to charge it every day

Add sleep tracking

Final thoughts

The Wellue O2Ring is a simple product that will record your Sp02 level, heart rate, and body movements while you are sleeping. From the week or so that I tested this device, I found that it worked as expected and I had no real issues with it other than the fact that it has to be charged every day. For the price, I am a bit disappointed that it doesn't also have sleep tracking features. It does show body movements, but I think it would be easy to also include sleep state analysis too.

Pros for the O2Ring:

-Convenient: Simply slip on thumb or index finger-turns on and off automatically.  May wear for continuous monitoring.

-Professional: Download a report for review or treatment via a smartphone. Used in hospitals.

-Easy to use: Turns on and off upon placing or removing ring on thumb or index finger.

Cons of the O2Ring:

-Battery must be charged every twelve to sixteen hours of use.

-Charges via micro-USB cable vs charging dock

# data[].attributes.body
The O2Ring is a nice product to have for intermittent or continuous wear to monitor oxygen saturation.  Before Covid, only those affected by severe respiratory issues had concern to routinely evaluate oxygen levels.  Now, with almost every household affected by Covid, more people are concerned enough to search for a sure, reliable method to monitor themselves.  The O2Ring is easy to use and meets all needs regarding monitoring of the oxygen level.

The purpose of the O2Ring is to provide intermittent or continuous monitoring of blood oxygen levels while having the ability to download via a smartphone app. Reports can be viewed and saved when needed. Alarms are used if levels drop below set ranges to gently wake the wearer.

We have all been living through a life-altering pandemic. As a result, words such as "oxygenation" and "pulse oximetry" have become mainstream and the general public has increased the use of pulse oximeters. This should come as no surprise since hypoxia (i.e., low blood oxygen level) is one of the hallmarks of COVID-19 pneumonia. Today, there are many affordable personal pulse oximeters on the market. Traditional clip-on designs have several limitations. For example, they do not allow continuous monitoring, which may be indicated for some individuals. Thus, Wellue, a Chinese-based medical devices company, has introduced O2Ring.

O2Ring is a finger ring-shaped pulse oximeter that will continuously monitor the user's peripheral oxygen saturation (SpO2) on the thumb. At Medgadget we were given the chance to try O2Ring for the past few weeks. Below is our review of the product.

Design and Fit

Wellue's O2Ring is made of flexible medical silicone and weighs only fifteen grams. It has a sleek, low-profile design. However, since its face incorporates a small LED screen, it is slightly bulkier than comparable devices on the market, such as the Oura Ring or SLEEPON's Go2Sleep ring.

O2Ring comes only in one size. The manufacturer recommends wearing it on the thumb or index finger. It is very comfortable to wear and stays securely in place throughout the day and while sleeping. One of the advantages of having a ring as opposed to a clip-on, at least for some people, is that the device can be used without the need to remove fingernail polish.

Usability

O2Ring is simple to use. It automatically switches on when you slip it on your finger and powers off a few seconds after taking it off. By tapping on it, the LED screen will illuminate and show your SpO2 and heart rate in real time. You can also view these readings via the smartphone app.

O2Ring uses vibrotactile feedback to alert the user if the SpO2 level drops below a preset level or the heart rate is out of a certain range. The intensity of the vibration can be adjusted.

The device is charged via a micro-USB cable. This is a drawback to the more convenient charging dock that its competitor, the Go2Sleep ring, offers. O2Ring has a battery life of twelve to sixteen hours and takes two to three hours to fully charge.

Software

Wellue offers a free app for iOS and Android smartphones. The O2Ring itself has a built-in memory that can store up to 4 sessions or 40 hours of data. Each session ends when the ring is taken off. When the app is launched, the data is transmitted to your smartphone, as long as the ring is within Bluetooth range.

Overall, the app is easy to use. Each session is reported separately with a simple overview of the data. It highlights the average SpO2 and heart rate, lowest SpO2 reading, the number of drops in oxygen level, as well as the time spent below a certain level. The report can be shared with loved ones or healthcare providers via email or text message. According to Wellue, the device has been validated for accuracy through multiple clinical studies.

Conclusion

We found O2Ring to be a convenient, easy-to-use pulse oximeter. It is a particularly appealing option for medical conditions that require prolonged monitoring of blood oxygen levels, such as sleep apnea, chronic lung disease, and more recently, COVID-19 pneumonia.

O2Ring can be purchased from Wellue's official website and Amazon. It retails for $165, which is slightly above the price point of other comparable products. Nevertheless, the device may offer peace of mind to both users and their loved ones.

According to the Clifton Strengths Finder, my top five strengths include input, achiever, responsibility, consistency, and harmony.

I would be an asset as a team member as reflected by input being my first strength. I like to learn, gather information, and store information in an orderly manner.  This would help to gather data as needed.  Second, I am an achiever.  I enjoy setting and reaching goals.  This would help a team by ensuring completion of projects.  Third, is responsibility.  Being responsible is a must for every person in a team.  Next is consistency.  I like to follow rules and standards I set for myself, and this is required when working with a group.  Confusion arises if one is not consistent.  Lastly, harmony is a listed strength for me.  I like everyone to get along and work well together.  This is needed when a team effort is required.  All of these strengths combined make me a good teammate.

# data[].attributes.body
When choosing teammates, I would choose teammates whose strengths would edify my strengths and I would theirs.

I would choose Carter who is a good communicator.  He is able to bring about ideas as well as present them.  Next, I would choose Daisy who is a developer.  She would be an effective teammate because she would pull ideas from others and help to build on them. She would encourage and help improve on their ideas and thoughts.  I would also choose Pablo.  He is a welcome member to the team due to his energy, and desire to see projects through.  He encourages others and makes them want to be like him.  Negativity even in one person can hurt the team so Pablo would be essential.  I would also choose Matthew who desires personal as well as group excellence.  He will maximize all our efforts to be the best at all we do.  Lastly, I would choose William with his strength to woo.  He would balance our team by helping to meet new people and connect with them.  This will help when providing information about products to influence a person's thoughts and ideas in a positive way.

I feel our team will be successful in bringing about information on the O2Ring and will effectively provide all the information needed to make it a popular item.
