FAQS
What is O2 Score?
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.

Why I get different readings by Oxygen Monitors of Wellue and other manufacturers?
Please be assured that all Wellue products provide medically accurately measurement.
Different manufacturers utilize algorithms with different average SpO2 times, which is a significant element when calculating the reading. The shorter the collecting duration, the more sensitive the result, the fast the response. Oxygen monitor with too long assessment time is not the best choice for oxygen saturation detection, especially during sleep. Wellue’s intelligent averaging algorithm collects data quickly and identifies the precise SpO2 value.
Therefore, it is not rigorous to compare oxygen monitors that utilize different averaging algorithms.The comparing result will be much more accurate if obtained by an arterial blood gas.
Could I log my data in the Apple Health?
Sadly, not now. The Apple Health log data in one-hour interval, while ViHealth app is 4-seconds, we think recording data in 1 hour won’t be very useful. When the Apple Health changes the recording interval to one minute or shorter, we would make it happen soon.

I have a question about the display of the graphic. If I go into detail (magnifying glass), the green line on the pulse display changes to green dots. Not long, sometimes 1-2 minutes when recording.
Does the line broken by dots mean that I have cardiac arrhythmias during this time ???
I would be very happy to receive a prompt reply.
Greetings Peter Grawert
Ich hätte da mal eine Frage zur Anzeige der Grafik. Wenn ich ins Detail gehe (Lupe) wechselt bei der Pulsanzeige die grüne Linie in grüne Punkte. Nicht lange, bei der Aufzeichnung manchmal 1-2 Minuten.
Bedeutet die durch Punkte unterbrochene Linie, dass ich in dieser Zeit Herzrhytmusstörungen habe ???
Über eine zeitnahe Antwort würde ich mich sehr freuen.

What does it mean when the pulse display changes from a green line to green dots in the ViHealth app, and does this indicate cardiac arrhythmia?
The change from a solid green line to green dots in the ViHealth app's detailed view (magnifying glass) typically indicates a change in data density or signal quality rather than a specific medical diagnosis like cardiac arrhythmia.
If you are concerned about heart rhythm irregularities, you should share the recorded data report with a healthcare professional. You can export these reports as a PDF or CSV from the app to show your doctor for a proper clinical evaluation.

Before purchasing the O2 Ring, the Customer Support Team at Wellue confirmed in writing that the 3.7 Vdc lithium-polymer battery was user replaceable. Now that I’ve had the unit for a bit and very happy with it, I reached out to them for instructions and a part number to order to replace it. Now they are telling me it’s not recommended for users to replace the battery and they don’t sell replacement batteries. Very disappointed in this. So what’s the story? Can a technically oriented person source and replace this battery or not?
Thanks.
Thanks.
Is the 3.7 Vdc lithium-polymer battery in the Wellue O2Ring user-replaceable, and can a technically oriented person source a replacement?
According to the official product documentation and current manufacturer policy, the battery in the Wellue O2Ring (Model PO2) is not user-replaceable. The device is designed as a sealed unit to maintain its structural integrity and sensor accuracy.
While the device uses a standard 3.7 Vdc lithium-polymer battery, there are several factors to consider regarding manual replacement:
If your device is no longer holding a charge and is under warranty, it is best to insist on a warranty claim based on your prior written correspondence with their support team.

Why can't I download or view data graphics in the ViHealth app even though the device shows records, and how do I fix the 'disconnected' status during sync?
Based on the manual and common troubleshooting for the ViHealth app, here are the steps to resolve data synchronization and 'disconnected' errors:
Note: As your device is 2 years old, ensure the battery is sufficiently charged before starting a sync, as low power can cause Bluetooth drops during data transfer.

I have a question about the beep that goes off. I’m wondering if it has a different beep if it freezes or is low on battery.?Last night I woke up to a beep that seemed different and I couldn’t get my O2 or my heart rate to change until I turned it off and turned it back on.
What do the different beep sounds mean on the Wellue SPO2 Monitoring Ring, and how do I troubleshoot a device freeze?
The Wellue O2Ring (PO2) primarily uses beeps or vibrations as reminders for low oxygen levels or abnormal heart rates, rather than specific diagnostic codes for system errors. Here is how to interpret and address the issues you described:
If the device continues to freeze or produce unexplained beeps, it is recommended to check for firmware updates within the ViHealth app or contact Viatom support at

When I connect my device to my laptop, it connects, but 1) all my previous reports are missing and 2) when I select download, I get a “create file error”. It appears all the other “functions” work such as configure, etc. I’ve detached the device and reattached (yes, I’m using the USB cable provided with the device), but no luck on reports. What do I do??
Why are my previous reports missing and why am I getting a 'create file error' when downloading data to my laptop?
The "create file error" and missing reports when connecting to a laptop usually indicate a permissions issue or a conflict with the PC software (O2 Insight Pro). Please try the following steps to resolve this:
If the device connects and allows configuration but won't transfer data, the internal memory may need to be cleared. Try syncing any available data to the ViHealth mobile app via Bluetooth first to see if the records appear there, as this can sometimes "nudge" the device's file system into responding.

I bought O2 Ring and I must say it’s a very good at tracking my Sp02 during sleep. I have sleep apnea and my oxygen level sometimes go dangerously low. I set the threshold at 88% and the moment it touches it wakes me up with gentle nudge. So even when there’s a drop and by waking me up it doesn’t go down further.
I am facing a few issues with the ring. The first one Elastic Band snapped in two month’s time. Since I was travelling abroad for a long the forgot about getting a replacement. After lapse of warranty time line the company offered me a new replacement ring for $105. The new ring developed some issue after 2 months of use. It fails to connect to my I phone app when I touch the round key on front display. I tried reinstalling the app, but it still doesn’t connect. It has now become useless to my cause.
I tried getting in touch with the office but no one cares to respond. The after sales service of very poor quality.
Now I find Walmart Canada is selling the Wellue O2 Ring. At least with Walmart I will have better service.
My suggestion to the buyers if you can locally get this product then go for it. It is far better than getting some faulty product shipped from China and engage yourself in useless and time consuming communication.

I have a Wellue SPO2 Monitoring Ring. the video shows a linker but there was no linker in the box. How do I sync it to my phone
How do I sync the Wellue SPO2 Monitoring Ring to my phone, and why is the 'linker' shown in the video missing from my box?
It appears there is some confusion regarding the hardware. The "linker" you saw in the video is likely for the Wellue Oxylink model, which uses a Wi-Fi hub. The Wellue O2Ring (SPO2 Monitoring Ring) does not require a linker; it connects directly to your phone via Bluetooth.
To sync your ring to your phone, please follow these steps:
If you are using an Android phone, ensure that Location Services are enabled for the ViHealth app, as this is required for Bluetooth functionality on Android devices.

How can I connect my O2 Wellue ring to my Airsense 11 cpap machine? Resmed has added an oximetery option to their machine menu but have given no instruction. Can you help?
How do I connect my Wellue O2 ring to a ResMed AirSense 11 CPAP machine?
Based on the manual for the Wellue SPO2 Monitoring Ring, there is no native or direct Bluetooth connection between the ring and a ResMed AirSense 11 CPAP machine. The Wellue ring is designed to connect to the ViHealth app (iOS/Android) or PC software (O2 Insight Pro) for data synchronization.
While ResMed may have added oximetry options to their menu, these typically require ResMed-specific proprietary accessories (such as the ResMed Oximetry Adapter and a compatible Nonin sensor) to integrate data directly into the CPAP's report. To use your Wellue ring alongside your CPAP therapy, you should:
If you are looking for a direct wireless link, please note that the Wellue ring does not currently support the proprietary Bluetooth protocols used by ResMed machines.

Why can I only see 15 minutes of history on the dashboard screen? The device is continuing to measure O2 and pulse but the display on shows the previous 15 minutes.
Why does the dashboard screen only show 15 minutes of history while the device is still measuring?
The 15-minute view you are seeing on the dashboard is typically the real-time monitoring mode. When the device is actively connected to the ViHealth app via Bluetooth, the dashboard provides a high-resolution live feed, but this view is often limited to a short rolling window (such as the last 15 minutes) to maintain app performance.
To view your full history and long-term recordings, please follow these steps:
Note: If a measurement session is less than 2 minutes, the device will not save the data for syncing.

The ring was excellent. I bought it late July on Amazon. Yesterday, 2 months after purchase, it just stopped working. Very upsetting. Not sure how to repair, if it can be repaired.
How can I repair my Wellue SPO2 Monitoring Ring if it has stopped working after two months?
If your Wellue O2Ring has stopped working after two months, please try the following troubleshooting steps before seeking a repair:
Warranty and Support: Since your device is only two months old, it should still be covered under the manufacturer's warranty. Wellue products typically come with a 1-year warranty. You should contact the seller (Amazon) or the manufacturer directly for a replacement or repair. You can reach the developer support at viatomtechnology@gmail.com or wangjiang@lepucloud.com.
Note: There are no user-serviceable parts inside the ring; attempting to open the device yourself may void your warranty.
