Back in May I upgraded to the new Medtronic 530G insulin pump and Enlite sensor. I started the new pump right away but I waited until I used up some of my old sensors (since Medtronic wouldn’t take back the ones I had bought with the old sensor after upgrading to the new sensor) and finally switched over to the Enlite two weeks ago.
It’s essentially the same as my old pump. It does have the threshold suspend feature in place but I don’t have it activated because it still concerns me how it handles my blood sugars. Being pregnant, there is a fine line between “low” and “too low”. Technically, I should be starting pre-meals as low as 60mg/dl but then if I’m in the 50’s I feel really low and drop quickly to 40’s. If I were to use the threshold suspend feature, I’m not sure what I would set it to, so for the time being, I’m not using the feature.
One thing I LOVE about the new pump is the pink color. In the past ten years or so I’ve basically stuck with the grey/clear insulin pump because it was more “professional” looking and I didn’t want to draw a lot of attention to it. Now that I’m older and don’t care as much and I also work from home, I thought it was time for a change so I changed the color to PINK!
One negative I have noticed about the pump is the battery life. I never wrote down concrete data but I’m pretty sure my old pump would only need a new battery every month or two. My husband bought a big pack of batteries for me and I didn’t go through them very fast. Now on the new pump, I probably go through a new battery at least once per week! One time I changed my battery and 36 hours later I needed to change it again. It could have been the battery but since they were from the same pack, I’m thinking it had more to do with the pump than the battery.
Overall, not much change between this pump and my old Medtronic pump. The battery life is a nuisance but I love my pink color. Note: I’ve been a Medtronic insulin pump user for 17+ years and I have been happy with them throughout-They have great customer service; I love the Silhouette infusion sets,; I love the buttons on the pump so I don’t need to look when bolusing or responding to an alert (with the aid of the sounds from the pump). I’ve contemplated switching pumps but I’m overall very happy with the pump-I wish it was compatible to an iPhone and had colors on the screen but otherwise I love it.
Eek, where to start with this one. I’ll start with the pros:
Pro: The insertion process is AMAZING! It’s so much easier than the old sensor, like night and day how much easier it is to use. I think if I had had this sensor insertion process all along, I would have a much different impression of the sensors (I hated the old sensor at first because it hurt so bad to insert!). Another pro is that it lasts 6 days versus my old sensor’s 3-day lifespan. True, I did “trick” my old sensor to last longer than the 3 days but it’s still nice to use the new sensor and know that I’m not “tricking” it. The tape that comes with the sensor also holds really well, almost too well-almost too well, the tape is no joke! A final pro is that after the initial 24 to 36 hours, it is very accurate. I had issues with my old CGM in the past and it’s accuracy. It wasn’t just the first 24 hours with the CGM, it was all the time. It would tell me I was 60 if I was 100 or 100 if I was 60. I felt a lot of the times it wouldn’t alert me to a low properly. I don’t have this issue with the Enlite sensors…I’ve found it to be very accurate after the initial day or two.
Con: There is really only one negative with the new Enlite sensor but it’s a MAJOR CON. The accuracy the first 24 hours (or 36 hours) is AWFUL. The first day I put the sensor in, I had major struggles with the accuracy. It was saying I was 40 for about 3 hours straight; I was around 100. Overnight was the worst. It wouldn’t come up from saying I was in the 50’s even though my blood sugar was perfect. I had the worst night’s sleep ever. The first 24 hours with this new sensor really make me debate if I should switch to Dexcom. After I get over the initial hump, things are fine, though. Since I’m only two+ weeks into the sensor, I’m going to wait and see if the first 24 hours improve at all as time goes on. I’m really hoping they do. It wouldn’t be worth it to me if 1 out of 6 days were inaccurate; that’s a very high percentage when dealing with diabetes control especially when pregnant.
I do have two other small negatives for the CGM. First, if I have my CGM and infusion sites on different sides of my belly, I like to keep my insulin pump on the side where my infusion set site is so the cording can stay on the same side. Often the CGM can’t seem to talk to the pump if it’s on the opposite side of my belly. I don’t have a huge belly (despite being pregnant) so I think the range the CGM reaches is incredibly small. However, I noticed this with the old pump/CGM as well so I think it’s more a Medtronic issue than the new pump/CGM. Second, I can “trick” the CGM to go longer than the initial 6 days but the transmitter runs out of battery life around day 7 so there is no extending the CGM much longer than the initial 6 days.
If I can get past the first 24 hours of the CGM, I would definitely recommend this pump/CGM combo. One thing I love about Medtronic is that I only need the one device, the pump to hold my insulin and my CGM data. This is one major reason I haven’t switched yet to a different pump/CGM combo. However, if the accuracy doesn’t improve, I might decide to make a switch.
