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!
