How Blood Oxygen Saturation Tracking (SpO2) On Fitbit Luxe Works

The Fitbit Luxe can measure blood oxygen overnight while sleeping, providing useful health tracking information. This feature wasn’t available when the tracker launched in April, but was unlocked in October of 2021 via a software update. However, there are some points to be aware of to ensure it works as intended. This is a useful health metric to track and medical professionals make use of similar data to diagnose sleep apnea.

Blood oxygen saturation (SpO2) is the percentage of the user’s blood that contains oxygen. Oxygen levels and SpO2 readings tend to remain relatively steady, even when exercising or sleeping, but they do vary and a trend of lower numbers might be worth checking with a doctor. The Fitbit Luxe measures SpO2 by shining red and infrared light on the skin, as richly oxygenated blood reflects more red and poorly oxygenated reflects more infrared.

The Fitbit SpO2 app is automatically installed on devices in select countries. However, if it is missing or has been removed, it can be manually added by opening the Today tab on the Fitbit phone app and tapping on the device listed under the user’s profile. From here, the user will need to tap on Apps, locate the SpO2 app and then install it. Fitbit Luxe’s SPO2 data is captured while the wearer sleeps and can be reviewed the next morning. While sleeping, the wearable will need to be worn in a position that keeps the back of the tracker in contact with the skin.

What To Know About SpO2 Recordings

The average resting SpO2 might take about an hour after waking to become ready and can be viewed by swiping up on the clock face and checking the SpO2 tile. SpO2 trends can be found in the Health Metrics of the Fitbit app on a paired smartphone. SpO2 readings are typically above 90-percent but can vary with activity level and overall health. It should be noted that altitude will also affect the measurement since the air thins and there is less oxygen at higher elevations.

With blood oxygen measurements added to the Fitbit Luxe, the fitness tracker gains another health monitoring ability to help the user stay aware of any changes to their overall health. However, Fitbit does note that these readings do not replace medical advice and a medical professional should always be consulted with any concerns.
