How Accurate Is Oura’s Respiratory Rate?

In an analysis that compared Oura’s photoplethysmography (PPG)-derived respiratory rate metric to an electrocardiogram (ECG)-derived method, the Oura Ring was shown to be accurate within 1 breath per minute across the entire night when compared to medical-grade research tools.

UCSF TemPredict Study

UCSF is testing whether physiological data collected by the Oura Ring, combined with responses to daily symptom surveys, can build an algorithm to identify patterns of, onset of, progression of, and recovery from, COVID-19.  

How Accurate Are Oura’s Heart Rate & HRV Measurements?

The Oura ring performed near-perfect for resting heart rate (r² = 0.996) and extremely high for heart rate variability (r² = 0.980) when compared to a medical-grade ECG device.
