I diligently calibrate my Medtronic 670G EVERY night before I go to bed. My pump keeps waking me up 4 to 5 times a week alerting me that it must be calibrated at 2 or 3 or 4 AM. I ignore it because I want to sleep! It then shuts off automode. (Sometimes it is because my BG is low. In that case I understand why it wants to be calibrated.)
When my BG is 150 in the middle of the night can someone please explain to me the algorithm. WHY does it need to be calibrated in the middle of my sleep? It makes no sense.
When my BG is 150 in middle of night, and I ignore the alert, does the Algorithm keep track of that info and request a BG night after night? The reason I ask this is because I was told by a Medtronic educator that if I do a finger stick during the day and ACCEPT it on my pump the algorithm remembers this and will request a BG at about the same time the next day. Who would write an algorithm like that? She told me to not validate my BG’s unless the pump asks for a BG or calibration. Only exception to the rule is I always validate my BG and calibrate at bed time.
Does anyone else have the middle of the night request for calibration after calibrating before bed? Maybe I need to shut off auto mode for a week and “reset” the algorithm. Any thoughts?
I have had T1D for 54 years and have been on Medtronic pumps for almost 29 years.
