Feature Request: Display "Low" and "High" for out-of-range glucose values #503
Description
Feature Request: Display "Low" and "High" for out-of-range glucose values
Context :
My 6-year-old son’s school caregiver uses LoopFollow. Recently, my son’s pod was ripped off, and his blood glucose (BG) rose to 22.3 mmol/L. Because the app continued to display "22.3" every five minutes, the caregiver assumed the system was working normally and did not realize the value was "out of range" or that the sensor had capped out.
The Dexcom Follow app uses "Low" and "High" labels to signal that a value is dangerously out of range and that the sensor can no longer provide an exact numerical measurement. Implementing this in LoopFollow would help non-technical caregivers immediately recognize when action is needed.
It became evident to me while I was at the school replacing the POD and trying to explain how I determined remotely that something wrong was happen.
Thanks.

The colour of the BG reading should change if the values are out of range - yellow if high and red if low.
I agree that a warning label would be useful, but the page is pretty busy already so would need to be careful. In the short term, can the caregiver setup alarms for high and low values so they get warned?
(On a separate note, we gave our daughters school a care management plan which includes actions to take at certain BG levels - happy to share with you if it could be helpful)

Sorry if I was unclear. By 'Low' and 'High,' I am referring to values below 2.2 mmol/L and above 22.3 mmol/L (40 mg/dL and 400 mg/dL). On the Dexcom Follow app, when these thresholds are reached, the app stops showing numerical values and displays 'Low' or 'High' instead. I believe LoopFollow should do the same to signal that the sensor can no longer provide a specific measurement.
Regarding the caregiver management plan, thank you for the suggestion. We already have a plan in place and have provided a two hours training, but I might add a one-page summary for quick reference.

Ah - I see what you mean. We are still on Libre 3+, waiting for the supply to run out before switching to Dexcom.
Would make sense to signify in some way that the reading is out of the sensors range so potentially in a worse scenario than suggested.
