For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (http://www.cr3diabetes.org), which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

Thank you all for such a warm and welcoming reception. I have added my wife Sally to my profile, as we are working as a team on my new venture with Dexcom.
It has been a great two days.

What are we using to attach to belt? Has anyone tried attaching something like this... http://www.theclip.com/store/product.php?productid=16371&cat=0&...

Some days I just dont have pockets or a purse handy! I also have a spi belt, but that is not ideal for outfits.

Me, personally, I would trust the meter over the dexcom any day of the week. The dexcom is excellent for spotting trends throughout the day, but I would not suggest to dexcom beginners to correct for highs or lows based on the dexcom alone. In fact, my suggestion is for the first few days of starting with the dexcom, just carry, the unit and go about your daily business as if you didn't have it.

As far as it interrupting your sleep, it would help to know what your low alert is set at, what your BG was when it was beeping, and if you have the snooze set. Although not recommended, you could disable the low alert, although if it thinks you're under 55 it will still make noise.

So, say your alert is set to 80, and your BG is at 85 when you go to sleep. An alert will go off once it hits 80 or lower. Another alert will go off a few minutes later if the first wasn't acknowledged. If the fall rate exceeds the set alert limit, it will also beep or vibrate or both. If it keeps going down and hits 55 or less, it will beep and/or vibrate 4 times until acknowledged. At this point, you probably want to check your BG with your meter. If that says you're at an acceptable number, and you feel ok, there is probably an issue with the sensor, transmitter, or receiver. In my experience, if it says I'm below 55, I've NEVER tested above 65... but moving on, once the BG level starts to rise, and it hits 56 or above, it will send another alert that you are below 80 (again, or still, I don't know why)

So, if you hit 55 throughout the nights, at a minimum you would have received at least 3 alerts at different times.

The alarms on the Dex, although not as customizable as I would like, can be changed - there is a snooze setting and you can make it more than every 5 minutes - so that as long as you acknowledge the low it will then wait until the next snooze time to let you know you are still low. I don't know if the low low setting (below 55) is the same though.

I think that although meters can be up to 20% off, they aren't usually that far off. The Dex isn't accurate enough to rely on it to treat lows or correct highs anyway - so I've never really worried about it. We use it to warn us of highs and lows and to detect trends (what always happens during and after basketball, what does pizza really do, etc.) After a couple of days is when the Dex is the most accurate, which is probably partially due to the fact that it's been callibrated more times so the error becomes less.

I just watched the dex video on this page, for the second time after viewing it a few months ago. I finally know enough to ask a couple questions. When I did the 1 week trial some months ago, I had two consecutive early morning (while sleeping) alarms. I treated myself both times with sugar pkts I had at bedside. Both times the darned thing kept beeping every few minutes because we know it takes a while for the BG to rise after treatment. That really interrupted my sleep two days. Does this mean I have to go through the menu and do a "shut off" in order to prevent the 2nd, 3rd, etc alarm beeps? That, too, would awaken me!
Second: we all know that our meters can be up to 20% off +/-. So it seems to me you could be entering a 20% error into the dex when you calibrate it. The dex I had was very much in line with my 1 touch. But it makes me wonder which was wrong during the 10% time the two were off. Was it the dex or the meter?!

I would appreciate thoughts on either of these issues, preferably both.

this silly thing ! it works great and then its off by 100 0r 50 how the heck can i fine tune it so as not to be off so much !when it works its great =-) but when its off ...dexcom said 120 and i tested with my one touch 55!

Just got a replacement receiver... does anyone know how to transfer the data?
Comment by Andrew Tumsuden on June 16, 2011 at 4:22pm
Not likely will work if you get a free one because the sensors are mighty expensive
Comment by Kim3 on June 16, 2011 at 2:28pm
Well Insurance's Suck!!! We soo wanted a Dexacom and my deductible is just too much...I wanted to know if anyone knew of ANYONE not using their Dex anymore? My son is 8 and really wanted to try it! I have an omnipod PDM and one pod to trade...major disappointment!!
