# Wellue O2Ring

Ring-style pulse oximeter that records overnight blood oxygen and heart rate with vibration alerts.

The O2Ring is a continuous ring pulse oximeter that records SpO2, pulse rate and motion through the night, with optional vibration alerts when oxygen drops. Many CPAP users pair its data with OSCAR or SleepHQ to see oxygen alongside therapy events. It is an oximeter, not a full sleep test, so share results with your sleep physician.
