Glossary
Blood oxygen saturation (Sp02) Your blood oxygen saturation level is the percentage of your blood that’s saturated with, or contains, oxygen.
Intended Use
The Fitbit Sp02 feature (“Fitbit Sp02”) is a standalone software general wellness product. It is intended to display to users the average range of their blood oxygen saturation as measured during their most recent period of sleep. This information is displayed to the user on their wrist-worn Fitbit device using a clock face.
Users who have a Fitbit Premium subscription can see past Sp02 values in the Fitbit app on their phones. Fitbit Sp02 is intended for over-the-counter (OTC) use for general wellness purposes. It is not intended for real-time or continuous monitoring of Sp02 values. Fitbit Sp02 is not intended for medical purposes, nor is it intended to diagnose, treat, cure, or prevent any disease or condition.
Product Description
Fitbit Sp02 is a general wellness standalone software product that uses data from a consumer-grade Fitbit device that has photoplethysmography (PPG) sensors. PPG uses red and infrared LEDs to shine light into the skin. The reflected light is measured and provides PPG data. These sensors are commonly used for general wellness purposes such as heart-rate measurements, sleep tracking, and other general wellness features found on fitness trackers/smartwatches.
The Fitbit Sp02 software is a standalone software product that uses data derived from PPG sensors to estimate blood oxygen concentration during periods of sleep. Fitbit Sp02 uses the sensors in compatible wrist-worn Fitbit devices to estimate your Sp02 average and range while you sleep. Install the clock face and wear your compatible device to sleep. After you wake up and sync your device, your Sp02 average and range are displayed on the clock face. If you have a Fitbit Premium subscription, you can see your Sp02 trends in the Fitbit app on your phone. For more information, including a list of compatible Fitbit devices, see help.fitbit.com.

Additional Information
What is Sp02?
Your blood oxygen saturation (Sp02) is the percentage of your blood that’s saturated with, or contains, oxygen. The oxygen levels in your blood tend to remain relatively constant. even during exercise and sleep.
How is Sp02 measured?
When the clock face is installed, your Fitbit device measures your Sp02 while you sleep. Your Fitbit device tracks your Sp02 while you sleep using red nnd infrnrflc:1 sensors on t.he b,xk of t.hfl devices. The sensors shine red and infrared light onto your skin and blood vessels. and use the reflected light that bounces back to estimate how much oxygen is in your blood:
- Richly oxygenated blood reflects more red light than infrared light.
- Poorly oxygenated blood reflects more infrared ligl1t than red light.
Note that you might see the red and infrared sensors continue to blink for around 30 minutes after you wake up.
What should I know about Sp02 values?
Sp02 values naturally vary, and nigh-lime Sp02 is usually lower than Lhan day line Sp02 due to the fact that your breathing rate is usually slower during sleep. In general, Sp02 values during sleep are typically above 90%. The Sp02 values presented are,;,n estimate. and in general can be influenced by your activity, altitude, and overall health.
Why did I receive a low Sp02 value?
When using Fitbit Sp02, you may notice an Sp02 value that seems expected. This can be due to:
- Your arm position and movement
- The position and fit of your Fitbit device
- Limited blood flow to the surface of the skin
- Differences in anatomical body structures can also impact the accuracy of your Fitbit device’s sensors.
Several factors can affect your body’s ability to maintain blood oxygen levels. These include, but are not limited to, the following:
- There must be enough oxygen in the air you are breathing.
- Your lungs must be able to inhale air containing oxygen and exhale carbon dioxide.
- Your bloodstream must be able to carry oxygen throughout your body.
An issue with any of these factors could impact your Sp02 values. For example, in high altitudes, the air is less dense and therefore contains less oxygen. If you experience low Sp02 values while at high altitudes you may want to consider descending to a lower altitude.
Certain health problems can also impact the body’s ability to take in oxygen. These factors can be compounded under more extreme circumstances such as during intensive exercise.
You should not use or rely on Fitbit Sp02 for any medical purposes. If you have concerns about your health, you should consult your healthcare provider.
