I have been having some issue with my sensor while I am asleep. Most of the time it goes out of range, or I get the 3 sets of ??? . the dexcom is usually right next to the sensor. Anyone have this issue ever?
Get out of here!!! We've only been using it for a few weeks. We have had this problem since the very beginning. Our first sensor was bad (combination of ??? or out of range all night) for three nights and we took it off. The second one was bad for two nights and then the receiver went bust. Then the next sensor was bad for 4 nights and then ok (not perfect but at least we had some readings) for the next 7. We just started our fourth and the first night was nothing but ???. Last night was the second night and it came to life about 2am although didn't have complete accuracy. That is a vast improvement from 4 nights of nothing but ???.
It works perfectly during the day though. It's like Caleb goes to sleep and so does DexCom. Anyone I asked seemed to think I was absolutely crazy. Although I'm sorry to hear you are having this problem, I'm glad to know we aren't the only one. Tech support has not been able to provide any guidance.
this annoys me because the big reason I have this is to catch an overnight low!!! And then I woke up this morning at 250 (felt kind of crappy also) I went to bed at 98,wonder how long I was over 200, because my dex had no readings for at least 6 hours!!!!
I just toss the received into bed with me. When i roll over it just floats around and magically ends up in the right place. The body is full of water and if you place it between the transmitter and your receiver, a lot of the signal is absorbed. That's what my Dexcom trainer recommended. I've not had aa ??? or out of range reading since i started sleeping with it. I keep an old cell phone case on the night stand and slip dex into it when i get up, pinned to my sleeping shorts.
1. The 7+ definitely has the best range when there is line-of-sight between transmitter and receiver. Currently I wear my sensor on my LEFT love handle straight down from under the arm pit. I noticed some missing data points during the day when I had the receiver in my RIGHT pocket. I solved the problem by moving the receiver to my LEFT pocket. At night I keep the receiver on my night stand. When I turn so that my body is between the transmitter and receiver I lose connection. I toss and turn enough so that I am not out-of-range for hours. If I wake up during the night and the receiver has no readout I turn towards the receiver and within 5 minutes I get a reading. I don't wait out the 5 minutes because the 7+ will alarm me if I am outside my defined bg range. The data points that I see make sense. For example, if the trend is downwards and a few data points are missing the next data point will be lower.
2. Readouts change when physical pressure is applied to the sensor. I read about this on CWD and my observations seem to validate the theory. When this happens the readout looks very erratic. Steady for a while and then a drastic change followed by no data points. With my sensor attached to my side I know that I exert pressure. The line looks like pieces from different graphs that don't belong together. Going forward I will chose spots that I don't lie on.
I've been getting those missing points too during the night. I've been trying to figure out the "spots that I don't lie on," both for comfort and to keep the sensor unsquished. Can't quite figure out where those are! I'm thinking about trying the bottom of the thoracic level, below my back ribs, at the point where my side turns into my back (if that makes any sense). Seems like the lumbar curve might keep the sensor out of trouble.
it happened again last night! This is really getting me mad, because I have been having some issues with my morning BG's. Last night I went to bed 102 and woke up 237 with large ketones!!! It has been a crappy day today because of it. I am now thankfully 94 with no ketones (they went away pretty quickly, kind of suprised they were large). I called tech support and of course they had no solution for me!!!!
Oh my gosh! Are you serious? Could it just be THAT easy??? Perhaps it being on the hard surface of the nightstand like we had it interferes somehow??? How does DexCom NOT KNOW THIS???? I need to create a pillow or something for Caleb because I keep having to swim around for it in the middle of the night. I tucked in into a teddy bear's collar last night - that worked well! :)
