I've been on the fence about switching to the latest pump and sensor from Medtronic because of what I've been reading here. I know this system has been use in Europe from some time before it was approved for use here. So I guess my question is, has this sensor always been a problem?
great question. I switched from dexcom ( which I loved) on advice of my endo and CDE. Gave dex to friend. I have made peace with the MM system, but it is no where as reliable as dex. I actually test more often, than with no sensor. at times , it is right on, but cannot be trusted.
I used Medtronic CGM for several months, stopped for maybe a month, decided to give it another try for another month or two. It's cumbersome (but not impossible) to calibrate, somewhat painful or at best uncomfortable, expensive and inaccurate, and, takes up valuable real estate on my belly that I hope to use for infusion sets for years to come. I never did fewer finger sticks while I used CGM so it ended up being hard to justify to myself why I was using it. People claim that the most important thing they get from CGM is data on trending highs or lows. Maybe, but I never, ever trusted the accuracy of the readings so why would I care what it said about trends, based on spotty data? Some people like it but it wasn't for me. Been off CGM for a year and don't miss it. I would, however, love, love, love to use a system that actually worked.
Hi. I tried the CGM with my Minimed 723 pump a few years back and did not like it at all. I also did not find that the benefits outweighed the painful insertion and same amount of finger sticks. At the time, though my A1C was much better and I really didn't find the CGM helped me. In the last year or so I have become "sensitive" or brittle as some people put it to any changes to my body and have dropped dangerously low a few times. I checked into the new 530G system and new CGM sensor that Medtronic is offering right now to see if I wanted to upgrade. They assured me that the new sensor insertion is much easier now with less bleeding, shorter needle and a straight insertion instead of the old 45 degree angle which was hard to get. I'm still debating the cost of upgrading and having to also pay for the sensors in addition to my infusion sets. Hope this helps you a little. I'd also be interested to hear if anyone has tried the new system. Good luck to you!
Not having that 45 degree would be really great but if it's not accurate or has problems more so than what I am using I hesitate to switch. I'm also am considered brittle and most of my lows are at night and I can sleep through an earthquake so having the threshold would be a big benefit.
I am using the new 530G with the CGM. I can honestly say, it is a major improvement as far as comfort is concerned. And the insertion is much better than the harpoon version was. It does take a few times to master the application process. I highly recommend a short training session with minimed.
Now accuracy, although still not fully perfected, has improved. I have run the shut off feature and have had a few instances where it has alarmed and shut off. I have been running it for about a month. Most of the time it has gone off during the day and I have had a few overnight. The alarm is loud enough to get my attention. Most have been triggered by real lows but a few were calibration error.
That is my experience so far.
My big problem is with the sensor bending. I teach yoga and the stomach area does not work. Lying on it also makes it bend, so the side body does not work. Tried my quads and it bended when I slept. I have managed only 3 days at a time because of this. any ideas?
Are you referring to the wire inserted under the skin bending? I thought it was the scar tissue under the skin that causes the bending. I assume that you have low body fat. For me, I am 26 percent body fat so I have no issue with using my abdomen. I have heard of other people using their thighs or upper arms.
thanks Chris. I will try my thighs again. Upper arm may be difficult to maneuver.
