How to measure your SpO2 on your smartwatch #WearableWednesday
Measuring your blood oxygen level became a daily routine for many over the past few years. Now wearables have added SpO2 sensors. The Verge has an article on how they work, their limits and how to use them.
If you’ve been hunting for a new smartwatch, you’ve probably come across the terms SpO2 sensors, pulse ox, or blood oxygen levels. SpO2 sensors measure your blood oxygen saturation — or, put more simply, the amount of oxygen you have in your blood. In fact, these sensors and metrics are included in most modern smartwatches and fitness trackers. The only issue is that not every wearables maker uses these sensors in the same way.
