Yes - something like that.
We live in the mid-west - and maybe its been around for awhile - all I know is that most of the Physicians I run into have never heard of it and Dexcom said they just introduced it within the past year. As a matter of fact, Dexcom said I was only the 10th customer they had in the Kansas City area with their CGM - who knows - maybe it was a sales tactic - all I know is that it works well for me.
It just does not show you what your glucose reading is - it puts it on a trend map and you can see the trend of your readings for the past 3-hours, push a button and you can see the trend for the past 6-hours - 12-hours and 24-hours.
Then you can plug it in your computer and print this info out as wells as the last week-month-3 month intervals.
I simply print this info out and you can clearly see a trend develop: Here is and example, by looking at my trends, I noticed that at around 2pm to 5pm my glucose readings were consisting running low on the week-ends - especially in the warner month - Bingo, I am usually outside working on Sat, therefore easy up on the Humalog on Sat. Lunch
Or my readings were running consistanly high on Thursdays after lunch - Bingo, that is Rotary Club meeting day and they do not have very many diabetic lunch options.
But like i said the best thing is the beeping when its low (below 60) or high (above 200) - it makes me correct the problem right then and there.
My lows are not as low and my highs are not as high.
I live in a rural area nad the last thing I want is to be in the midle of nowhere with a low glucose reading that I can not recover from. This thing will beep with plenty of time to correct the problem.
