Hi All. I've been using Medtronic pumps for almost 25 years. I tried the Medtronic CGM about 4 years ago, but I hated all the alarms constantly. I have just gotten a new CGM and have a appt with the Medtronic rep in mid-December to give it another try. One of the things that concerns me is that I will be spending so much time making sure everything is working. I'm so used to just living my life, testing my blood (7-9X/day) and keeping in relatively good control. But reading all the info on setting up the CGM, calibrating, etc., etc., I'm concerned that I'll be at work and that darn alarm will go off to remind me to calibrate, or something else. The beauty of the pump has been that I don't have to worry what time it is or if I need to eat because it's lunchtime. I can skip meals if I so choose. Someone please tell me that I'm going to appreciate the CGM once I get it going. Thanks.
You test often enough that the pump will never have to tell you to test. MIssing meals is a lot easier with the sensor because you don't just have a reading to go by, you can see what your sugars have been trending since your last test. I find the sensors very inaccurate when compared to finger stick testing, but I love the ability to see the trends. More importantly, despite many false alarms in the middle of the night, I have been awakened quite a few times by the pump signalling me (accurately) that I am having a hypoglycemic episode. Those occasions, where the pump and sensor have saved me from some very dire consequences, make me very happy to be using the cgm indeed.
Our experience exactly!
Agreed. I'm hypo and hyper unaware, too, and I NEED that CGM to tell me when I'm in trouble. And you're right about brand preferences too -- the Medtronic works better for some, and the Dexcom for others. Which is why I would advise anyone considering a CGM to see if they can get a loaner first, to see how it works for them. The Medtronic's information is better, in the sense that you can backtrack to see what your numbers were, and the sensor information on the pump is good, but if it's not accurate for you, then it's not an important factor. The Dex doesn't tell you anything except what your current BG is, and where you're trending, but those are the most important things to have accuracy on. So I'm hoping that Matchmo gets a chance to make the decision based on info from both sides.
My 12 year old daughter uses it and I don't know what we'd do without it! I'd give up the pump before I'd give up the cgm. We rarely have "meter bg now" alarms because she does test frequently and generally you just need to calibrate every 12 hours...so breakfast and dinner...but she tests for snacks, lunch etc. except occasionally on a weekend when she had a snack at 8:30 pm, didn't need testing the rest of the night and is sleeping in past 8:30 am. Not often! We set her low prediction at 90 which means it does go off when her numbers are good, but she doesn't always feel the lows coming on so this forces her to check. The cgm isn't perfect, but if you give it a chance it is a valuable tool. It sounds like you do a great job without it--and you are used to living without it which I think makes it harder to adapt to the cgm. I wish people could get it close to when they start pumping--adjusting to both at the same time is easier. Good luck!
I got my pump and cgm about 3 months ago and at first I loved my pump but hated the cgm. The alarms were going off so often. I was so fed up and I talked with my rep and she suggested adjust the threshold for my highs and low and calibrating when I wake up, dinner and bed (so it doesn't wake me up). I have to say after doing that, it has been smooth sailing.
The cgm has prevented a lot of lows and it has helped drop my A1C by 1.5% in about 2 months.
Like others have said, it is not completely accurate, but what I look at is not really if the number on my meter and the number that the sensor match up, but where my glucose is going.
I think you should give it another shot. It does take some time, but I think it is a very valuable tool.
So glad you stuck with it!
looks like most issues have been covered here. I often set the alarms to "vibrate" so I don't create a disturbance when they go off. Go to main menu>utilites>alarm>alert type; then set it to whatever choice suits you. It's really quick & easy.
I've cut my finger sticks down to about 3 to 4 per day and am getting used to watching the trends more so than the actual numbers.
In the 9 months I've had it, it has kept me out of the emergency room!
Once the FDA gets thru dragging their heels, the new style sensor should improve things, a lot. That new sensor has been available overseas, for about 3 years already, and users seem to love it.
I used it, also got "CGM burnout" and then stopped for quite a while. Now, I have turned the high setting off completely, as I do not find it useful. I insert the night before, and the calibrate in the AM, and this way I skip the two hour waiting time, which seems to make it more accurate. I only calibrate in the AM, before lunch, and before bed. I also takes some time to get used to not freaking out about the differences between the meter and CGM.....If I give it time, the numbers on the CGM usually catch up, it is just slower to respond. Also, I used to try to get 6 days out of it, and now I give up usually at 5, which is usually when I start to get calculation error readings. Means the sensor is just kaput. Once I get one calculation error reading , I do not try again, as it just continues to give CE readings, no matter what.
Now, I am almost rarelu bother by the alarms. If I am doing something really important, I just turn the alarm settings off.
I find it useful, but also really look forward to the new sensor in the future.
Hope (& everyone else), your comments have really helped me relax about using the CGM. I really like the idea of putting in the sensor before bed then calibrating in the morning. I'm sure I'll also mak use of the vibration alert or simply turning off the high alert. I think I understand the idea of watching it for "trends" rather than comparing the actual readings. Fortunately, I'm still pretty aware of highs and lows, and my husband helps me catch the ones that I don't see right away. Once I start actually using this (December 13), I'll look for more help too, I'm sure. Thank you all. Isn't it fun living with diabetes?! All these new gadgets and gizmos? I just try to keep up so that I can live ANOTHER 40 years with this fun condition! Happy Turkey Day, ya'll.
