Comparision of early warning systems that are available.

There are also a lot of studies and research links at the bottom of the page.

These were initially developed for parents with a diabetic child who was too low to say they are low…
But with hypoglycemic unawareness ever present, I think it is useful for adults as well. I bought a dex com for my 10 and 19 yr old boys, but it's so clunky.

What do you think?
Are any of you in the community using early warning systems?

I dislike both the medtronic and dexcom systems. I trialed them both and neither was accurate enough to warrant buying and using them. Within 4 days of the dexcom I had ripped off the sensor and packed up the system due to the low and high alarms going off throughout the night when my blood sugar was not low or high. The worst being when it read 42 but my blood sugar was 109. If you have to turn off every alarm and only end up with the hard wired "55" one, it's not very good. One time during the time I wore it was it within 10 points of my tested blood sugar, the rest (about 5 times per day) were 20-60 points off and generally didn't give a very accurate pattern to track.

Plus, the receivers from both systems look and feel like they would be right at home in 1985. For companies that say they are on the cutting edge of technology the actual user piece is about as behind as you can possibly get. If Verizon (or whoever) can cell a smart phone with an HD color touch screen, and allt the other features for free-$200 then you should expect a lot more for the prices that medtronic and dexcom are selling for.

I'll try either again once they have released 2 more versions but right now I don;t see any point in either unless you are extremely hypo unaware and don't mind false alarms.

I just got desitronic sensor…its amazingly accurate. I had the medtronic sensor for a while…talk about an amazing suck factor. The only part about wearing a sensor i dont dig is that i have to wear other stuff on my body. Dont like feeling like the million dollar man…and for me its hard to get tape to stick. Mastisol does nothing for me.

Wow! I have had the Medtronic sensor for three years now and LOVE it! It has saved my lilfe more than once. I love Medtronic becuz every time I have contacted them they have replied positively and once even stayed on the phone for an hour when they figured I was in insulin shock becuz I wasn't making any sense;I was alone in the Sandia Mountains. Yes, sometimes it sucks to have to have two things inserted into my body but now I am over it. Also, the Medtronic sensor isn't always as correct as checking my BG but, hey, it makes me check it. That is definitely not a suck factor.

Thanks for sharing your opinion. I love our minimed pump, and wanted to go with the sensor, but our endo was very against it. I haven't been able to talk to someone who actually uses the minimed sensor.

He said it was great for sensing highs, but was up to 40 points off on detecting lows. Since I was purchasing for my son for night time hypoglycemia, he said he didn't like them. I don't think he was operating on old information though. I have always preferred Minimed products. The one we did get is so bulky- my son won't wear it. I would rather have it all in one place..

That's awesome. I've heard medtronic is bad. I hope they come out with one unit soon. Two insertions is too much.

Kate, I had discovered these devices (CGM’s) myself recently and thought how useful these would have been to me (even at that cost) during my “discovery” phase in showing me in reasonably real time what foods did to me at meals. I did more research into them and started a thread (before you came on board I think) which got mixed reviews, some showing wild inaccuracies as well. On another site I found one entry that showed the CGM reading 40, but the actual meter test was 80. Several here have or are using them (put “CGM” in the search box, but you already know that) check out their responses.
I am surprised that with current technology, a permanent wireless sensor implant is not available for diabetics considering a frequency has already been dedicated to wireless medical devices.

Yeah, I get what you're saying about the inaccuracies. Our Endo advised us to go with the sensor that errored on the high side instead of the low. It's not a big deal to be off 40 points when you're over 200, but it's a huge deal when you're under 70. I'm excited to see the technology come together in the closed loop system. I hate putting two needle sets in my son. Minimed finished a very promising trial recently with their robotic pancreas. I can't wait till it's cleared for sale. Thanks for the link!

I was being taken to the ER numerously from work due to hypoglycemic unawareness. Once I got the sensor things changed drastically. I am now warned in enuf time for myself to deal with the lows rather than depending on someone else. Of course, after a while the alarm gets quite annoying and I ignore it. Could be the burnout talking here. But, I love it!

Definately a life saver for the hypoglycemic. There is already work on a transplantable drug delivery microchip - Remote Intelligent Drug Delivery System (RIDDS), so the robotic pancreas can't be far behind. I'm a bit leary of wireless technology with all the stuff in the airwaves now - imagine being able to "hack" a human being - but I figure soon we'll have BG levels delivered to your Iphone or tablet. Personally, I hope Islet transplantaion pans out (but sorry, I've already promised mine to dietcherry).

When they make somethinng that doesn't require blood and has an accuracy close to that of a lab and is relaible and not in the way all the time… or am I dreaming…

Not dreaming! I recently was thinking about how they can measure alcohol on our breath and thought why not sugar? Did a little research and someone had already thought of it. They are doing research at a university in CA. They have a ways to go. So far they can get high readings, but not normal or lows. I think it has great potential. Can't wait. How great to blow into a tester instead?!?

GabbyPA 2012-04-23 10:19:31 -0500 Report

That sounds so neat. I guess because there is not an abundant amount of sugar in our bodies when we swing low and that is what triggers it. We are so close!
