Yesterday was a very long day — not only was it Daylight Savings Time, so we “lost” an hour… but I was up until 1 am on the phone with Medtronic’s 24/7 help line. (That is something I do love about them – their customer service rocks.) I decided to put my CGM (continuous glucose monitor) back on around 10 pm – later than I would usually do it but it was a busy weekend. When I first put on the sensor (the part that is inserted under my skin), I wait 20 minutes, and then attach the transmittor (looks like a flat mushroom – it’s the part that transmits the data to my pump.) Then once the transmittor is attached, I wait 2 hours and it’ll beep at me, prompting me to calibrate my blood sugars – I have to test with my meter, then put that number into my pump, and it gives it a starting point. From there, the CGM will read my blood sugars 24/7 and I can look down at any point and see not only what my sugar is, but a graph of the trends. I have to calibrate it 2-3 times a day (you can do it any time of the day, but it’s best to do it before meals, because it needs to be a steady number – not on its way up or down.)
So I put in the sensor and wait the 2 hours. It beeps at me, so I get up, assuming I need to calibrate. I look at the pump to turn off the alarm and it says “Lost Sensor”. What? It’s right there – can’t you see it? Ugh. So there is an option to “Find Lost Sensor” so I did that (takes 15 minutes to “find” it.) Three times. Finally, around 12:30 am I called the helpline. After doing all kinds of tests (thank goodness the transmittor itself was still functioning properly – those bad boys are not cheap!) we came to the conclusion that it was either not a good sensor, or it was not in a good place under my skin. The nice Medtronic man that was helping me said I needed to take out the sensor and either put another one back in or wait till the morning – uh, I think I’ll wait for the morning, thanks. Don’t want to have to wait another 2 hours to calibrate! 🙂 He agreed. Then I left the house without my goody bag of supplies so it’ll have to wait till tonight. Fingers crossed it’s in a good spot this time. I see my Endo again in 2 weeks and he’ll want to see 2 weeks of numbers so he’ll know if we need to make any adjustments or not to my basals.
