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. 

Main Function of O2Ring


1. Continuously tracking oxygen levels and heart rate up to 16 hours.


2. Alarming for abnormalities by silent vibration.


3. Records of oxygen drops, average oxygen levels, and heart rate provide oxygen scores and trends over time.


4. Provides detailed sleep reports as PDF/SCV/Binary, easily print and share.

What makes O2 Ring stand out?

O2Ring is designed to provide accurate insights without disrupting your life. With precise sensors, O2ring packs Blood Oxygen Level(Spo2), Pulse Rate, Body Motions, and sleep monitoring technology into a lightweight, soft-wearable ring.

1. Continuous monitoring


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


O2Ring makes difference, with a built-in memory design, it could continuously take records every second and store up to 4 groups of 10-hour data.


The continuous data provides detailed insights into your health, and your historical data reveals how your body performs dynamically over certain periods of time.


Access to continuous data is critical for many patients with sleep or breathing problems, such as Sleep Apnea, COPD, or other chronic diseases.

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.

  • What is the meaning, “Beyond the threshold”?
    What does one have to do for readjustment?

    Heinz
  • I am not able to set the pulse rate threshold. this is externally important to have this feature ASSP

    Annette
  • I am suddenly experiencing the same issues. Constantly alarming pulse, unable to set/reset oxygen and pulse alarm thresholds. Need help.

    Pat K
  • Since the update no longer able to set HR threshold but alarm constantly going off. It is imperative that this is working as it is being used for heat condition. Please advise. Thank you.

  • Device not let me set the pulse rate or PR upper or lower level limit. Constantly alarms now. Did not do that previously. There must be a bug in the software. Tried to reinstall the software on my iPhone and it’s still doing it. I tried resetting device and it’s still doing I’ve done a reset of everything that I can do, but it’s still not retain pulse rate warning level, especially the upper threshold but both seem to be a problem. Please contact me when you have a fix as this is essential for an elderly parent. Otherwise the device is quite useless.
