It's been about 5 weeks since Emma started on the MM real-time sensors, and I just wanted to share how things have been going!

So far we're getting between 6-9 days from every sensor. Today is day 9 on the current one and it's still giving fabulous readings, but I'm sure it could "die" anytime. The site looks good, so I'm going to push it a little longer and see what happens.
The accuracy has been far better than I ever expected. It's much better than we ever got with the Guardian RT. Within 10% during stable numbers and usually within 20% during a rise or fall. I get many readings that are within a couple of points of the meter. Pretty amazing!
I've learned that soaking in a warm bath can skew results and shorten sensor life, (it's the temp, not so much the water). Jumping on the trampoline can cause a calibration error, (I'd bet any really jarring activity will). Laying directly on the sensor for many hours can cause a false low.

Basal adjustments are super easy because the trend is so clear, you really know when and where to make adjustments.
Her standard deviation is now 55 points which is great!
The graph on the pump shows not only the trend arrows to help you see whats coming, but also makes a note of every time you give insulin right on the graph, so you can estimate when it will peak very easily.

Overall I couldn't be happier! I really hope everyone gets to use this technology very soon!!!

Here are graphs of the past few days. The blue line is the sensor data, and the black dots are from her meter. (the round ones are used to calibrate, the square ones are not)

The error here is a result of Emma laying directly on the sensor site for several hours. This has happened twice in the middle of the night. As soon as she moves it corrects its self, no re-calibration needed.

Here's the pump screen w/ graph and current blood sugar. The grid lines show where I have the high and low alarms set, (it's adjustable). The little mark on the bottom of the screen is an insulin bolus. Very useful!

Amy,

I'm writing this while i have not yet even fully read your post.
Congratulations.
From the buttom of my broken heart.
It's fantastic.

Alright, lemme see...

There's this "diabetescgms" YahooGroup. Not one of those over-trafficed ones. Maybe even quite cozy to some extent. Have a look.

I believe you already know that http://www.insulinpumpforums.com also has a separate messageboard about MMRT.

warmwater, trampoline and laying... thanks for the tips.

SD... John Walsh recommends an SD of <60, Someothyer place i read that SD should be less than 50% of meter average, but we didnt get a good hang of the SD thing until we calculated it ourselves using one of these scientific calculators. Turns out even BIG variations in BG may not be 'shown' in SD i.e. one may have an SD of 30 WITH one or two 70 point variations in the day. We concluded that a good SD is ~25 or less.

These are what i've decided to do when we get ours (hopefully a month from now):
. Testing/adjusting/verifying Basals
. Testing/adjusting/verifying Carb Factors
. Testing/adjusting/verifying Correction Factors
. Testing/adjusting/verifying DIA
. Assessing the effects of excersise
. Finding the best dual/combo match for each and every food we usually have.

I'm VERY happy for you.

Congratulations Emma's mom!

We are also using Minimed's CGMS, and i agree with all you've said. We are finding it very accurate also. We try for 12 days with each sensor, but have had 3 now die about day 8-9. We love it!

Great! Very happy for you. I hope the A1C will improve in line with the standard div. Keep us posted. (I am dreaming of a CGM.)

BTW, is it only me that I cannot see the charts?

Thanks.

----------------- Ooops, I just noticed that this was an old post from EmmasMom. How is the CGM 10 weeks on?

Thanks! I know this is an old post, but I fixed the pictures. I didn't realize they were gone...:o I did a 3.5 month update too.:)
