When my kid went on to the 780g + Guardian 4 (previously was on MDI and Dexcom G6), it all seemed great even though the Guardian 4 needs changing every 7 days versus 10 for the Dexcom.
And the lines on the Guardian 4 graph on the pump looked so smooth.
I now don't know if I can trust Guardian 4 any more, however. Over the past month, we have had ONE sensor run to 7 days, and one week where one sensor failed after less than 24 hours. All other sensors during the month seem to have failed at least 2-3 days prior to the sensor change date.
But the worst part is, we have had multiple occasions where the sensor reading is so far off, it's not even delayed - it's just plain wrong. Example: today my kid felt unwell at school. SG was 12. School decided to finger prick to check (well done school!). She was 24
Two hours later, her sensor says she is 9. Finger prick says she is 17.
And this is not the first time - it has been happening multiple times. If we look at the graph on the pump it all looks nice and even - but the blood glucose tells another story. We've tried massaging the sensor site, calibrating (do that too much and the sensor goes), etc. but the core of it is I'm not sure we can rely on Medtronic's claim that the Guardian 4 doesn't need calibration, or chacking - these days we're now checking 2-3 times a day just because we've lost so much trust in the tech. Any ideas/experience with this? Is it my sense that the Dexcom was just more accurate correct?
