I am officially hooked up to a Guardian Real Time System. They gave me a whole new setup, so I felt like I was getting it "for real" and that I didn't have to give it back in a month. I am unsure about my feelings of it yet. It is too soon, and I've had too many issues. From the beginning:
One of my biggest fears was wearing and inserting the sensor. I was expecting the insertion of the sensor to hurt like &^*$ because it went in at an angle (angled sites and I have a bad history) and then the nurse offered me ice, saying most everyone used it. After about a minute of sitting there with the ice on my stomach, and getting more nervous by the second, I just went for it. I did not hurt a bit. It takes a little bit of work to get the inserter off of the site, and it is a little nerve wracking. With a pump site, you mess it up, and it's not that big of a deal. With a sensor, it's like flushing twenty dollar bills down the toilet. Overall, a lot easier than I thought. It actually hurt less than my pump sites.
After my training was done, they sent me on my way, with the instruction to do a 2 hour calibration check before the system would actually start working. Not 15 minutes down the road, I got a "sensor error" alert. Not exactly what I wanted to see. After pouring through the manual, I finally found out that one of those alerts is really no big deal, but multiple alerts aren't so great. Ok, I'm good to go. I thought. Until 20 minutes later, when I got the same alert. Soo I called the Minimed people, who had me restart the 2 hour start up period. So 5 hours after my initial appointment, I was finally getting readings. For a few hours, it went pretty well. I checked the number on the screen every 15 minutes or so, just for the joy of it. I felt like it was fairly accurate, until about half an hour ago, when I could feel myself falling. But the graph stayed steady. As I was walking back to my room from a friends house, I became more and more sure that I was dropping. But the Guardian did not agree. I know it takes some time to catch up with rapidly changing numbers, but I felt like I was dropping for a good half an hour. I checked, and my meter said 75. Not exactly an emergency, but not the 188 the Guardian claimed. Here's where I made my first big mistake: I plugged that number into the Guardian. Bad move. It needs calibration numbers that are not rapidly changing. After it thought for a good long while, I got a "cal error." So I'm not getting any data now, and I'm in the waiting game for my blood sugar to even out so I can calibrate it again. I'm hoping it becomes more accurate as time goes on, and I learn how to best take advantage of this technology.
