Can the Fitbit Versa 4 track blood oxygen levels continuously

To access this data, you need to wear your Fitbit Versa 4 to bed and then check the Fitbit app in the morning. The app will display your average blood oxygen saturation levels for the night, along with any variations that might indicate breathing disturbances during sleep[6][7]. These variations can be important for detecting potential health issues like sleep apnea[4][7].

While Fitbit does not offer real-time or continuous blood oxygen monitoring during activities, some other brands like Garmin provide a "test my SpO2 now" feature, which allows for on-demand measurements, though not continuously during exercise[3]. Therefore, if continuous blood oxygen monitoring is a priority, you might consider devices from other manufacturers that offer this capability. However, for sleep-related monitoring, the Fitbit Versa 4 is effective and provides valuable insights into your overnight oxygen saturation levels.
