O2ring Usage Guide

What is the O2ring?

O2Ringcould continuously track oxygen levels and heart rate as a smart home-use health monitor. Transmissive oximetry technology has medical-grade accuracy and is more accurate across all finger sizes.

With 4 groups of 10-hour data storage, it could work independently or together with Vihealth App. The battery could last 12-16 hours after one charge.


Wearing the O2 ring will automatically start to track your overnight blood oxygen saturation, heart rate, and body movement continuously. It will silently vibrate to remind you when detecting too low blood oxygen saturation or irregular heartbeats. Of course, you can customize the reminder.


The device is connected to the APP via Bluetooth, after you take it off, the data will be uploaded to your Vihealth APP automatically. You can also sync the data seamlessly to your PC software, and share detailed personal overnight oximetry reports with your sleep specialist. Your sleep report shows the statistics of oxygen levels and pulse rates, making it an excellent reference for the home sleep study.

2. Accuracy Above All


When you visit your doctor, there’s a reason they measure your pulse from your finger and not the wrist—accuracy. Your finger is the ideal source for reliable, impactful data. We do have studies showing that reflectance oximetry (used in AW7) is not as accurate or stable as transmittance oximetry (used in fingertip pulse oximeters.) Read More. Using an intelligent SOC chip, combined with anti-interference filtering technology, O2Ring provides a more accurate SpO2 level and Pulse Rate measurement in real-time.
