Secure, stable probe connection for accurate readings
-
Upgraded memory frequency for consistent, high-quality results



Never Miss a Single Drop in Overnight SpO2
The O2Ring S ring pulse oximeter upgrades sampling frequency from 150Hz to 200Hz — reducing the temporal sampling interval from 6.67ms to 5.00ms.
Low perfusion and restless sleep no longer compromise accurate sleep monitoring. The 50 additional data points per second deliver cleaner waveforms and reliable detection of the shortest, most transient overnight desaturation events for confident clinical decisions.

Sleep Apnea Screening/HSAT
No lab beds to prepare and no sleep technicians to equip. Viatom O2Ring S ring pulse oximeter expands sleep tests from stressful lab stays to convenient home sleep apnea testing (HSAT) with a lightweight, comfortable ring worn by the patient.
Embrace meticulous monitoring with zero sleep disruption and artifact-free data for confident sleep apnea diagnosis.


Home Lung / Respiratory Diseases Monitoring
Real-time SpO2 readings actively boost CPAP patient adherence and engagement.
The O2Ring S serves as a reliable CPAP companion who provides long-term monitoring for a virtuous "Identify → Intervene → Improve" cycle. This approach leads directly to fewer exacerbations and superior therapy outcomes.
Remote Long-term Connect
Powerful battery life, automatic data upload, and offline in-device storage ensure Viatom O2Ring S ring pulse oximeter delivers complete, uninterrupted data with no fragmentation.
When an abnormal blood oxygen level occurs, the ring oximeter vibrates instantly. Patients remain sensitive to their condition, and providers stay fully informed.
