Blood Oxygen Saturation (SpO2)
SpO2 (Oxygen Saturation) is a measurement of your blood oxygen level. The Fitbit devices use body sensors to record the percentage, average, as well as the minimum and maximum levels of oxygen circulating in your blood while you’re asleep. This allows you to better monitor your vitals and general health throughout the day.
Developers can use the following API endpoints when integrating the SpO2 data type:
- Get SpO2 Summary by Date returns single date summary data.
- Get SpO2 Summary by Interval returns interval summary data for a specified date range.
If your application has been granted intraday access, the following endpoints can be used. See Intraday.
