Does the Oura Ring track oxygen levels?

The Oura Ring, which is designed primarily as a sleep and activity tracker, does not track oxygen levels. While it monitors various parameters such as heart rate, heart rate variability, body temperature variation, and movement during sleep, it does not measure blood oxygen saturation (SpO2). Devices that do track oxygen levels are typically known as pulse oximeters, which can be standalone devices or integrated into certain smartwatches and fitness trackers. However, as of the current generation of the Oura Ring, this feature is not included among its capabilities.
