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 do not want to turn off the high or low alarms. It would be defeating the purpose of CGM. Turning off the alarm would cause more unaware hypo or hyer. One of the purpose of CGM is to help control DKA, but if you turn off the high alarm, you could go into DKA and never know.
As other’s have said, I’d give up the pump, before giving up CGM. In fact, I didn’t get the pump, till they had CGM. CGM is what makes reasonable control possible (mostly because of all the alarms that seem so anyoing.)
Also, as you indicated, the trending information is what is most important. The only problem is, the effing way they map ISIG numbers coming from the sensor to glucose numbers makes it near impossible to get trending information. Every time you recalibrate, it reverses the trends from reality, trying to get the glucose numbers back in line, so you have to try to guess what the pump is doing, to figure out what the real trending is, it totally suckkkkksss!!
Has anyone been able to figure out the effing algorithm they use for this calibration mapping? And why is it so off all the time – especially with the all important trending information???
Even if you could just see only the uncelebrated ISIG numbers that didn’t require calibration, you could at least see some real trending information. Why the eff can’t you at least do that??
We soooo need to jail break this system.
Well, it's been a while since I've posted, but I wanted to update everyone on the CGM. I sat down the Medtronic rep on December 13 and have been "hooked up" since then. Things are going great! I LOVE being able to watch the trends. One note, we have NOT yet turned on the alarms for highs and lows, since fortunately, determining those are not a huge issue for me. Our main goal is to watch what's happening with my blood sugars 24/7, and then be able to make the appropriate adjustments to my basal and bolus rates on my pump. My only complaint so far has been getting "Weak Signal" alerts, especially at night. Historically, when sleep, my pump goes where it wants. Now I feel the need to keep it hooked to my undies on the same side as my sensor. Since I've done that, no more "weak signal" alerts. I left the first sensor in for 6 days with no issue. It took me a while to insert a new one--just making sure I was doing everything in the proper order! But I remember doing that when I first got my pump 30 years ago too. I know it will become more routine quickly. Oh, and I'm also using the CareLink so that my doc can see my readings from her office from time to time. Life is good. Control will get even better as I go along. Happy Holidays to you all!
Glad it is going well. I have noted the same thing. At night I clip the pump to my PJ bottoms, on the same side as the sensor or else I get low sensor signals.
How do you avoid the 2 hour waiting time by inserting at night?
I don't think you can. If you are concerned about this, count the days from your placing the sensor and replace it before it usually conks out.
It means not using it one night, the night that you insert. I insert a new sensor, attach the CGM, and then go to sleep. I press "start new sensor" first thing in the AM, and it asks for a reading almost immediately, usually within 1-3 minutes.
(my first comment ever... here it comes:) I have been on CGM for almost half a year now, and I consider it, generally speaking, a great experience. of course it's not a perfect technology, but as you get to know it - it really rocks.
Understanding when and how to calibrate is one of the most important thing. I used to Calibrate when the pump told me, but then I realized there are better times - Mostly, you should always consider the ISIG number and the way it flatulence... I found out that after sitting for a while/sleeping or having the sensor covered by a blanket and so, it's less stable. ---
Sometimes when my BG ain't good I prefect not to calibrate at all and be a few overs with out sensor, until I have the chance to calibrate it correctly (80-180).
BTW, I've been using the ENLITE, which is much better from the previous generation...and I've heard some rumors about the next one ;)
Hope it helped a bit.
The enlite sensors are for the new pump which, together with the sensors, are due to be through FDA approval by the end of 2013. I do not know if they will work with the paradigm pumps.
Good to know! Thanks Alon
I am new to the pump. I just started in the begining of Nov. I started the CGMS the first of Dec. I really do like it. At first I would freak out when I seen the differeneces on my pump and my tester and I would really freak when I would see down arrows but I kept it together and went by would the blood tester told me and all was well. I kept the first sensor in for six days and it worked great but I quickly learned that I can only make the sensor last about half way through the 5th day which isn't too bad. On the 5th day I start getting crazy numbers that aren't even close to the blood tester. So I have been changeing my sensor on day 5 now. The biggest issue I have is some bleeding and getting the dang needle back out after I insert. I have been using a 60 degree angle as instructed by my pump rep. Last time a changed I went through two sensors due to bleeding had a terrible time getting the needle back out, it hurt really bad. I tried the 45 degree angle the third time and it seemed to be better for me, so that is what I am going to try again. The only thing about changeing it I dread is pulling the needle back out cause I have a really hard time with it and it often hurts really bad when it pulls out. I also love it cause I am testing less often about 4-5 times instead of 10 or more. Saves me money on the strips and I am doing so much better with my anxiety about lows. I am excited for the new sensor my dr is going to try to get it for me when it comes out. I am excited about how easy the pump rep said it is to insert!:)
