What is the best overnight oximeter for home use? - Wellue O2 Ring Oxygen Monitor review


So, you thought you’re sleeping well and even dreaming about cute, pink unicorns.

You probably are.

But, you may also experience sudden breath stops or oxygen deterioration in the blood. In short, Obstructive Sleep Apnea or OSA.

I doubt that!

Yeah, well, normal people don’t really experience its symptoms and it’s not that easy to detect during the first phase— you only wake up lethargic and feeling sleepy during the day. And you may think, “Oh, I only need some sleep.

Whether or not you have sleep apnea or your partner complains about your loud snoring every night, perhaps it is time to monitor your sleep.

Duh. How do I track it if I’m sleeping?

Two words:

Wellue O2Ring.


This is the tagline of the Wellue O2Ring— a medical-grade ring that monitors and tracks your sleep, silently and immediately vibrating when abnormal heart rate and/or low oxygen levels are detected.

Smart, huh?

Well, check this out:

Wellue O2Ring Features

●       Overnight Tracking: Track your oxygen levels, heart rate, and even body movements every second, continuously. Oxygen Level Range: 70 – 99 percent. Pulse Rate Range: 30 – 250 BPM.

●       Silent Vibration Alarm: When low oxygen levels and abnormal heart rate is detected, the O2 ring has a built-in silent vibrator to wake you up but not your partner. The vibration intensity and threshold can also be adjusted to your preference and needs.

●       Free Monitoring Software & Apps:For full reporting and sleep trend analysis of your heart rate and oxygen saturation, you also have access to free Windows (7/8/10 OS) and macOS(version 10.15.3 or above) software and Android/iOS app (Android 5.0 or above; iOS 9.0 or above; iPad 3/iPhone 4s or above).

●       Detailed & Smart Reporting:It provides you a detailed trend chart with a 4-second interval. Very detailed reporting, it tells you how long your oxygen falls below 90 percent and how many times your O2 drops over 4 percent for the whole night. With the high-resolution chart, you can zoom in and out to see more detailed information and even the exact values when it happens.

●       Export Professional Report: With the free monitoring app and software, you can print and/or export or share CSV/PDF analysis reports with your doctor.

●       Built-in Memory: The small device can also work standalone, monitoring, tracking, and storing data on the device without being connected to the app or software. The ring can store at least 4 sleep sessions, each lasting at least 10 hours, with all of your data syncing to your smartphone or PC once connected.

●       Rechargeable: Of course, it is rechargeable. Its battery can monitor and track your sleep for up to 12 – 16 hours. One charge equals to 2 nights of monitoring.

Frequently Asked Questions

Q: Which finger is recommended?

Q: How to pair Bluetooth?

A: Don’t pair in your phone’s system setting. Just make sure that Bluetooth is enabled on your phone.

A:Remove the device from your finger. The data will be ready for sync after the countdown. Open the App to sync. Or you can also sync while wearing the device. Just open the App while wearing the device to sync data.

Take note: If measurement time is less than 2 minutes, then there will be no data saved.
