Wear your ring, close your eyes. OxyBridge streams your body's overnight physiology — SpO₂, heart rate, oxygen desaturations, and estimated blood pressure — live to your screen, in a clinical-style bedside display.
Three steps from your ring to a full picture of your overnight physiology.
Connect your Viatom OxyII ring to your Android device over Bluetooth. One-time setup, automatic reconnection after that.
NiteBridge streams your physiology continuously all night — waveform, oxygen levels, heart rate, and estimated blood pressure, updated beat to beat.
In the morning, explore overnight trends: SpO₂ dips, HRV patterns, and blood pressure variability. Your session data automatically syncs to SleepHQ™ and exports for OSCAR — no manual steps needed.
Everything you need to understand what your body does while you sleep.
A real-time plethysmographic waveform scrolls across the screen — the same signal used in hospital pulse oximeters. Motion artifacts are detected and labelled automatically.
Live and session SpO₂, Perfusion Index, Oxygen Desaturation Index at both 3% and 4% thresholds, and T90 — the share of the night spent below 90% SpO₂.
Heart rate, estimated blood pressure, respiratory rate, and a full HRV suite — RMSSD, SDNN, pNN50, MAP, and Rate Pressure Product — all derived live from the PPG waveform.
OxyBridge classifies your overnight BP pattern as normal dipper, non-dipper, or extreme dipper — a clinically meaningful indicator of cardiovascular health that a standard cuff can't capture.
Switch between METRICS, CHARTS, and BOTH views. Trend graphs for SpO₂, heart rate, blood pressure, and HRV RMSSD with time windows from 2 minutes to the full session.
Run calibration sessions with a Viatom BP2W cuff to improve estimated BP accuracy. The model personalises to you over time and grows more accurate with each session.
Your overnight SpO₂ data automatically uploads to SleepHQ™ after each session and exports in a format ready for OSCAR analysis. Your ring data lands in the same tools as your CPAP data — no manual steps required.
All metrics are computed onboard from the ring's PPG signal — no additional hardware required for monitoring.
Your SpO₂ ring data belongs alongside your CPAP data. OxyBridge puts it there automatically.
Overnight SpO₂ and oximetry data exports in a format OSCAR understands. Open it alongside your CPAP sessions for a complete picture of your therapy — breathing and oxygenation together.
Sign into SleepHQ directly from NiteBridge. Your ring session uploads automatically after each night — no zipping, no manual file management. Your sleep physician sees the full picture.
OxyBridge supports two Viatom ring families. OXYII models unlock estimated blood pressure and nocturnal dipping — all models support full SpO₂, ODI, HRV, and waveform monitoring.
Here's what you need to get started.
The blood pressure values displayed by OxyBridge are derived algorithmically from your ring's PPG signal and are not equivalent to a clinically validated cuff measurement. Do not use these readings for medical diagnosis or treatment decisions. Always consult a qualified healthcare professional regarding your cardiovascular health.
Stop sleeping in the dark. Get NiteBridge and watch your overnight physiology come alive.
