Welcome to the Fitbit Community forums, @91214ME.  

Thank you for the information provided about this issue you experienced with your Charge 5. 

If you removed the SpO2 app from your device, you can reinstall it with the Fitbit app on your phone:

1. With your Fitbit device nearby, in the Fitbit app, tap the Today tab > your profile picture > your device image.
2. Tap Gallery     Apps tab.
3. In the list of apps, tap SpO2 > Install > Install.

You should be able to see your SpO2 trends in the Health Metrics tile in the Fitbit app on your phone. To get SpO2 information, you need to: 

1. Wear your device for at least a full day, including to sleep at night.
2. In the morning, open the Fitbit app and tap the Health Metrics tile.
3. Swipe up to find the Oxygen Saturation (SpO2) tile.

If you still don't receive your SpO2 information, please follow the steps listed here below: 

1. Verify if your Fitbit profile has the correct location and time zone.
2. Open the Fitbit app, tap your profile icon > Charge 5 > Apps > SpO2.
3. Make sure all the permissions are enabled.
4. Restart your tracker using the charging cable to refresh its performance.
5. Tap Today at the bottom of the Fitbit app and pull down on the screen to force a manual sync.
6. Wear your tracker slightly higher on your wrist to sleep and sync it with the Fitbit app once you're awake to check your details.

Let me know if you continue to experience the same problem afterwards. 

I'll be around.
