I'm a huge fan of my Medtronic Paradigm 723 insulin pump, I love the CGM and everything that the pump has to offer. When my cellphone, Facebook and Twitter pages all started going nuts because of the new Medtronic insulin pump I couldn't help but be excited. Everyday diabetes technology is changing and with the blink of an eye we are getting closer and closer to the much anticipated "artificial pancreas" To read all that the new 530G insulin pump has to offer please click here.
The new pump is able to temporarily stop insulin delivery once sensor levels fall below a predetermined level. For example, if my low alarm is set for 70 once my CGM reads 70 or below my insulin pump will automatically suspended This is great news for many but I believe this is not the major insulin pump revolution that many imagine.
I suspend my insulin pump at least once a day while I'm at work. I will see or feel that my blood sugar is falling, I also know that I will be active for the next two to three hours. I need to nip that low in the butt, I want to keep working, I don't want to take ten minutes to fix a low blood sugar of 50. If I can suspend sip juice and eat a little while still working I'm happy. Does that mean the new 530G is perfect for me?? No, the new insulin pump suspends once you hit a certain number, lets say I set my alarm for 75. Having it set for 75 means that I'm probably at 60 if I was to test using my glucose meter, the CGM is giving me my blood sugar anywhere from five to ten minutes before. The simple fix is to set my low alarm for 100 which it is currently at, the problem with that and the new pump would be what if I'm sitting watching TV for the day. Can I cancel the suspension? I'm sure that I can with no problems but I have yet to see that information anywhere.
On to my biggest problem with the automatic insulin delivery suspension feature. What about the insuiln that it is already in my body? I have been told that using the suspend feature on my current pump is to only be used if I'm suspending for more than an hour. Fast acting insulin takes anywhere from forty-five minutes to an hour and a half to start working. My problem with the new pump is that it does what I was told not to do by many doctors. If my blood sugar is at 80 and falling at 7:15pm after eating dinner and taking a meal time bolus of five units at 5:50pm the suspension of the insulin pump wouldn't touch my meal time bolus. That insulin is already in my body and has already started working, the suspension of the insulin pump would stop my evening basal rate, not the insulin that caused the low.
As alaways I need to state that I'm just expressing my feelings and views. I have done my share of research and have not seen any information that covers what I just wrote about. Diabetes technology is going in the right direction and I'm very excited for the future but I believe that the new Medtronic 530G is not the future, it is current technology with a small new feature. I group this new pump with the new Iphone color, it is the same device with something that does nothing to better how the device performs
