1. Garmin Forerunner 255

Exercise is one of the best ways to raise blood oxygen levels. The Garmin Forerunner 255 is the company’s best SpO2 watch, the most reasonably priced running watch suitable for cyclists and swimmers. It has an All-Day Pulse Ox that monitors your oxygen levels every 5 to 15 minutes. Additional features include a spot-check watch face and a sleep-only option.

Your battery life will be reduced if you install the Fitbit SpO2 app and watch face. Your most recent score will appear on the face, and your nightly averages will appear in the app. However, there isn’t a spot-check SpO2 option, and you need Premium to view your nightly SpO2 data going back more than a week.

3. Garmin Venu 2

It provides you with the top-notch Garmin stats and data you’re accustomed to but with a lovely AMOLED display for a more fashionable appearance than the company generally offers. Additionally, just like other Garmin trackers, you can choose to turn SpO2 tracking on the smartwatch oxygen saturation throughout the day or while you sleep. It can withstand the blood oxygen battery hit better than any Fitbit or less expensive Garmin device thanks to the 11-day battery life.

4. Apple Watch Series 8

The class-leading health monitoring of the Apple Watch Series 8 has undergone some substantial improvements from its predecessor.

By pressing your finger on the digital crown, you may quickly and efficiently take an ECG or monitor your blood oxygen levels. Otherwise, you can configure the Blood Oxygen app on your watch to send SpO2 readings while you’re dozing off or immobile. As an interesting side note, a Theater mode option dims the screen and turns off SpO2 readings to prevent distraction from the sensor’s flashing lights.

Conclusion

Beyond the sensor’s actual physical location, however, how the Pulse Ox truly functions on your watch and how the software uses the data are as crucial.
