Sensor not reporting properly after inserting new sensor and waiting for 2 hours. Readings are bad until at least another 3 hours. This has repeated on each new sensor.This is very common, and has a widely-used solution among Dex users on this board: Shoot in your "new, replacement" Sensor many hours BEFORE you make your switch. Several people do this overnight, and then execute the "Sensor Stop" - "Swap Transmitter into the New One" - "Sensor Start" sequence the following morning. Have you tried this already?
I have had unit receiver unit swapped out by dexcom and second unit works worse.You and I agree that Dexcom should replace it. Did you warn them that you will send an additional, future letter of complaint to the FDA if they don't agree to send you a functional unit, accepting the failed unit for analysis under your failing conditions (i.e., warm room)?
Receiver Unit overheats inside and flatlines. Chilling it back down stops that and unit recovers.... FDA says get a 3rd unit dexcom receiver and try. Did request weeks ago - no success. Dexcom not sent requested 3rd unit. FDA could care less.
Unit misses faster cycles of BG due to pancreas activity and over smoothes data.The way you wrote this statement hurts your credibility (if written to someone like me, or to the FDA). Unless you have both the microcode source AND an adequate set of raw datastream versus "true" bG values, you can't analyze whether they're "over-smoothing" or not. (Report what you know: the "missed" changes versus properly performed fingerstick measurements. Don't make a mess of your letter by gooping it up with unqualified guesses.)
Sitting in Condo - many times receiver has wondered off track with 20 to 30 points off - requiring loading cal BG's frequently. This unit was supposed to reduce finger pricks and costs - not so, I am constantly cross checking this flake product.I'm with Jim Devlin on this one: If you're expecting to be within 20 points when you're watching TV, or otherwise "hanging around" (without the kind of SC blood flow you have while walking around), you need to poke for it. You can NEVER trust a current-technology CGMS to replace fingersticks, and all the documentation says so.
I have contacted FDA without any success or assistance. I do not know who these folks are protecting? Not me and not the 13 folks killed on a PQQ technology BG handheld meter and strips in hospital setting.PQQ is irrelevant to CGMS. Avandia is irrelevant to CGMS. If you want to see improvements in this technology, then you probably should not pour a bunch non-relevant disasters into a big tar-bucket, and then associate CGMS with those mistakes.
