I am having a terrible time with my sensors. For the past two months with many sensors, many placement sites, two different pumps and two different transmitters, daily, I receive messages of sensor error, weak signal and reset to warm up. If I am lucky, the cgm system works four or five hours a day only and the readings I do get are more inaccurate than ever. Has anyone had this experience? What did you do to correct it, if anything.
Switched to Dexcom G4. Problem solved.
Dex is amazing sensor. Agree with mary. Switch tomorrow.
How do you receive the signal from the Dexcom?
Is the transmitter charged? Are you inserting the sensor at a 30 degree angle?
Transmitter works just fine. It is fully charged. This has happened to me over two dozen times. I have been inserting at the default 45 degree angle. Called Medtronic today and they suggested that I insert at a 60 degree angle so that the cannula reaches further into my blubber.
Hmmm sorry you are having trouble. The only time I had trouble with the transmitter not sending a signal was when I thought it was charging but the charger needed it's battery changed. After that everything worked like a charm. Hope it works better with the 60 degree angle maybe that will do the trick.
With the Dexcom I got a ridiculous amount of error messages like the "???" which supposedly means you are not getting a signal or the sensor is in a bad spot/not enough interstitial fluid. So I get your frustration with CGM. I have had pretty good success putting my MM CGM on my thighs/arms.
I've been using Medtronic CGMS since they came out with the first one. When I had this problem the Medtronic support desk asked me to perform a transmitter check with the little plastic attachment that comes with the transmitter. I asume you have done this, if not call Medtronic.
I too had to switch to 60 deegree, not because of being overweight, but because of reuse of area (yes I rotate across 3 different areas of my stomach and side, but usually do just one side of my body for the sensor). For me that helped. At one point I had to get a new battery charger (free) and later had to get a new sensor kit because mine was too old (about 3 years).
I saw a good question, of how do you prepare the sensor site? I use alchol pad to wipe, the use IV-3000 clear adhisive cover still in it's paper enclosure waiving to dry off the alchol. You DO USE at least one IV-3000 over the Sensor/transmitter don't you? Sometimes I have to put a second IV-3000 on to keep the sensor in place. Have you checked to see if the sensor seems loose (can move in and out)?
Thanks for the advice Fred, but I have checked both of my transmitters with the test plug and they are fine. Both of the transmitters are pretty new. The second one came with my new revel which I just received on an upgrade. I use Tegaderm instead of the IV-3000 because it holds much better and gives better coverage because it is larger. I will try the steeper angle and see what happens.
