I don’t know where I’m at with this.
The Medtronic customer service is phenomenal. Mostly phenomenal.* The Medtronic trainer has followed up with me and checked out my Carelink updates, giving me suggestions to improve my experience. The StartRight representative has been helpful.
My graphs and reports are, frankly, abysmal. My weight is up three pounds (and as an individual with food/weight issues, you know that doesn’t make me happy) and my A1C rose 0.2%, which may not be much, but I wanted it to go in the other direction. My CDE’s comment to me when she walked into my appointment was: “What is going on? These can’t be your numbers!”
Here’s the thing I like about the Medtronic MiniMed 530G system with Enlite: Threshold Suspend. It does work.
Except when it doesn’t for me.
There have been nights that the Threshold Suspend feature is activated. My blood sugar is 104 mg/dl when I check. I shut off the suspension and restart my basal. It alarms again. By this time, I’m up, out of bed, trying not to wake John, and angry that the pump is waking me up for no reason.
Twice in the past month, it has legitimately suspended and I’ve treated, thankful that it woke me. I’ve yet to sleep through an alarm. (Man, that alarm is loud.)
But I’m finding, for me, that the noise from the alarms compete with the noise in my head over my blood sugars. I’m questioning constantly whether the numbers I see on my MiniMed 530G insulin pump are accurate. When they are, I breathe a sigh of relief. When they’re not, I breathe a sigh of frustration.
That’s a lot of sighs.
I love my Medtronic MiniMed Revel. I’ve said that before. Medtronic has been very responsive with every issue I’ve had with the Medtronic 530G with Enlite system. (The CareLink issue? That’s another story. Quick side note: I’m hearing from others that I’m not alone in my frustration with CareLink.)
My goal with diabetes management is to keep blood glucose levels within my prescribed range while minimizing the intrusion of diabetes into my daily life. (It’s a Hurculean task some days, but others…) The technology I choose to use is meant to help minimize the intrusion.
The Medtronic 530G with Enlite is designed to help minimize the severe hypoglycemic episodes with Threshold Suspend – and it does when the accuracy of the Enlite sensor is working correctly. I’ve had meter readings of 45 and my Enlite sensor is telling my 530G pump that I’m 82 (and the arrow is not trending down). I’ve had meter readings of 64 and my Enlite sensor is telling my 530G that I’m 64.
It’s Me. But is it?
The rise in my A1C is because I’m over treating when I go low. I know this now. I didn’t over treat quite as frequently before I began the trial, because I could see the fall easily on the CGM transmitter of my Dexcom. It’s not as easy to see that on the screen of the 530G pump.
I’ve had to turn off the predictor high and low alarms and the high and low range limit alarms for my sanity. That, for me, lessens the ability of this technology to minimize the intrusion of diabetes into my daily life.
Others are not having these issues and perhaps it’s because their diabetes management is better controlled or their own diabetes is not marred by delayed gastric emptying or quirky days. I’m still not giving up on getting this MiniMed 530G with Enlite system to work for me.
Anyone have suggestions?
*The customer service issue I had? I called in on a weekend to get a few sensors replaced due to sensor errors. I spoke with technical support, who made some less than supportive remarks regarding how I was trained by my trainer. Not cool.
I was also told that when the pump tells me to “BG NOW” to calibrate, I should wait 10 minutes if I’m not stable… which to me says that the pump shouldn’t say “BG NOW”… and if you’re not trained properly or don’t know better, your readings are going to be inaccurate. But when you get a BG NOW for the first time during the wetting period, after two hours, if your blood sugars are fluctuating slightly up or down, how are you to know? These questions have me up at night…
