Medtronic's Paradigm Veo Wireless Insulin Pump Helps Prevent Hypoglycemia

The problem with that design is that the CGMS portion is unreliable (more so for some patients than others) so that when one is sleeping, chances are high that the CGMS will falsely report a low and shut off the flow of insulin, when in actuality the person's blood glucose is either normal or high. Been there, done that with the MM CGMS using the 522 that doesn't have the shut off feature, thank god.

My wife uses the CGMS and generally has decent results, but it will falsely report lows for her too, just not as often as it did for me. Be forewarned, folks, you DON'T WANT YOUR PUMP TO STOP DELIVERING INSULIN due to a flaw in the CGMS readings!!

It is not clear whether "just me" is fully aware of the algorithms that drive this device. I would not presume anything before speaking to a doctor.

"Dr. Green" you really don't get it: the fact is that the CGMS sensors aren't accurate enough to rely upon. All the algorithms in the world won't change that. IF you really are a doctor, I worry about your patients, because you aren't understanding the most basic issue here of sensor problems. Nothing within the pump can override the bad data coming from current MM CGMS sensors.

I agree that the sensors can be inaccurate. I often find myself testing every couple of hours just to make sure that the sensor readings are accurate. At night, I can be running in the mid-80s and it is reporting mid-50's. That was a common enough occurrence that I shut off the low glucose alarm because it was pretty much worthless.

When the sensor starts to get to the end of its life, it tends to "flat-line" at around 90 or so, no matter what my sugars do. You're not supposed to chase the numbers, but to watch the trends. But it soon becomes a question of how can I trust the trends if I can't trust the numbers the trends are based on.

When this current batch of sensors is gone, I won't being buying anymore. I might try the next generation and to be honest, the CGMS has helped me get my patterns better. I guess I would say that it would be good for occasional check of your trends, but for valid day-in-day-out information, it is just too unreliable.

I agree with the other posters concerns in regards to the accuracy of the CGMS. I too have the same problems with mine. Finger stick test 12 times/day because I can't trust the data coming from my CGMS.

Not only do I get false low's, I often get false highs. Or the CGMS will completely miss an extreme low. Very rarely is the CGMS accurate with my finger stick readings. It has helped in some regard to change my patterns but as Scott said for day-in-day-out data it's pretty much useless and extremely frustrating.

I have had both very accurate and inaccurate readings from my MM CGMS; it all depends on the user and how well they calibrate the pump, as well as how well they remember that the readings aren't real-time, they're about 20mins behind. If you keep those things in mind, it's a good representative of your bgl trends.

If you calibrate during an up or down trend instead of a flat, yes, your readings will be off at least until the next calibration.

I'm all for TEMPORARY insulin delivery suspension. The ends justify the means. Yes, hyperglycemia is bad over time, but hypoglycemia can kill or seriously injure in minutes.

first time user kind of scared of it !!
