This is not new to any of us, but am losing my mind with frustration. For background, I’ve lived with T1…specifically since the day Spiro Agnew resigned as Vice President…obviously a long time. I’ve grown up with the advances in techniques, treatment regimens, and technology. My frustration is simply this. I’ve used both the Dexcom 6 and mores the Medtronic CGM as part of my 670G. I’m educated, I’m experienced, and I’m also a certified Critical Care Registered Nurse. I understand technology and I am experienced with trouble-shooting as well as following “rules” and understanding “work-arounds.” My experience with both CGM versions is simply that in roughly 3 out of 4 sensors, I experience sensor failure…always due to absolute inability to be accurate with variance of between 50-300%, and often trending the wrong direction within 6-12 hrs of placement. I’ve remarked to my endocrinologist, who I frequently see at work for curbside consulting, that I would not allow this technology to operate in “Auto-Mode” to care for a dead animal let alone a human being.
Okay, I’ve introduced the origin of my frustration. Does anyone have any solutions for the following general scenario…solutions that are not the obvious as presume I have used any obvious solutions already. The General scenario is this…I insert the CGM (assume Medtronic version for this discussion), The link to the pump is flawless, I usually track my BG without calibrating for the first few hours (although I have also experimented with calibrating more after the warmup period without success), I calibrate according to instructions and pump indicators appropriately, and within the 6-12 hr period it is more often than not the SensorG is trending the wrong direction or simply errant by extreme percentages based on actual BloodG measurements. This is of course followed by Calibration error and sensor change instructions and sensor failure. I’ve experimented with starving myself for an entire day to avoid BG spikes etc to create and induced BG regularity for the sensor to learn from but this too is pointless.
Again, can anyone help with anything that is not just typical suggestions…e.g. rotate sights, follow the instructions, etc.?
Thank you in advance for any new help:)!
