My Initial Thoughts On The MiniMed 530G With Enlite

My Initial Thoughts On The MiniMed 530G With Enlite | The LOOP Blog

When my new MiniMed 530G with Enlite system arrived on my doorstep early November, excitement washed over me. It also brought temptation to rip open the boxes and get started right away, but I knew I needed to wait for my training session. Training happened smack dab in the middle of November, and now that I’ve used the new system for a while, I’d like to share some observations and some things I wish I had known.

Training is important

Recently, Naomi posted her thoughts about the 530G with Enlite Training, and as I read it, I nodded right along. I’ll admit, I was a bit cocky when my new system arrived, and I thought training would be a waste of time. In reality, I learned tons during my training session, which to my surprise took about two and a half hours. And beyond that, I found myself talking to the 24-Hour HelpLine a week later to get a refresher on Enlite insertion. I went from thinking I knew it all, to realizing how much I need to learn.

There is a learning curve

The good news? Inserting an Enlite sensor is very different from inserting a Sof-sensor. The bad news? Also that inserting an Enlite sensor is very different from inserting a Sof-sensor. After using Sof-sensors for almost six years, I had overcome any insertion fears. I definitely don’t have a light touch – I tend to shove those Sof-sensors right into me. But with the new Enlite serter, less is more. I’m learning to use a gentle touch. This lighter touch feels much more comfortable to me, and most times, I barely feel the sensor going in.

The HelpLine is a huge help

The first few times I inserted my sensors, I couldn’t get them to stick when I tried removing the inserter. A call to the Helpline put that problem behind me. Although the instructions suggest waiting 5 seconds after insertion to allow the adhesive to stick, my Helpline representative suggested I focus on site preparation and maybe try waiting a little longer to ensure the adhesive sticks. This worked like a charm and I’ve not had insertion issues since.

Threshold Suspend works

I was quite excited about the MiniMed 530G’s new Threshold Suspend feature, but at the same time I found myself a bit freaked out by it. But when it did kick in, I wondered what I had been so scared about. The pump alarmed loudly, I checked my blood sugar and treated my low, and chose the option to cancel the suspend. Easy as can be. A week or so later when Threshold Suspend kicked in at 3 a.m. (I have it set to 60), I decided to let it run its two-hour course so I could test how it worked for me. After the Threshold Suspend kicked in, I’m happy to say my fasting blood sugar stayed between 101 and 125 for the remainder of the morning. I feel an extra layer of security knowing I have Threshold Suspend as part of my pump.

The new sensors are more sensitive

I’m excited that the Enlite sensor is shorter and thinner under the skin, but I quickly learned this makes it more sensitive. Pressure from my waistband or lying on the sensor when I sleep didn’t throw off my Sof-sensor, but can sure mess with my Enlite sensor. So my normal go-to spots to wear sensors are shifting a bit.

Patience is key

I admit I was a bit frustrated with my new system during the first week. Then I took a step back and remembered how awkward things felt last time I trained on a new pump and continuous glucose monitor. I remembered pulling out my instruction books all the time for reference. Once I stopped expecting to be an “expert” and decided to give myself time to learn the ins and outs I felt much better and started enjoying my new diabetes technology.

Overall, I found the new 530G with Enlite came with a larger learning curve than I expected, but once I understood that and began moving along that curve, I really started to love my new system. And now, a few months in, I feel mostly back on auto-pilot again, and I’m happy to find the Enlite sensors are much more comfortable and accurate for me.


Medtronic Diabetes insulin infusion pumps, continuous glucose monitoring systems and associated components are limited to sale by or on the order of a physician and should only be used under the direction of a healthcare professional familiar with the risks associated with the use of these systems. MiniMed 530G with Enlite is intended for the delivery of insulin and continuous glucose monitoring for the management of diabetes mellitus by persons 16 years of age or older who require insulin.

Pump therapy is not recommended for people who are unwilling or unable to perform a minimum of four blood glucose tests per day. Insulin pumps use rapid-acting insulin. If your insulin delivery is interrupted for any reason, you must be prepared to replace the missed insulin immediately.

The information provided by CGM systems is intended to supplement, not replace, blood glucose information obtained using a home glucose meter. A confirmatory fingerstick is required prior to making adjustments to diabetes therapy. MiniMed 530G with Enlite is not intended to be used directly for preventing or treating hypoglycemia but to suspend insulin delivery when the user is unable to respond to the Threshold Suspend alarm and take measures to prevent or treat hypoglycemia themselves.

Warning: The Threshold Suspend feature will cause the pump to temporarily suspend insulin delivery for two hours when the sensor glucose reaches a set threshold. Under some conditions of use the pump can suspend again resulting in very limited insulin delivery. Prolonged suspension can increase the risk of serious hyperglycemia, ketosis, and ketoacidosis. Before using the Threshold Suspend feature, it is important to read the Threshold Suspend information in the MiniMed 530G System User Guide and discuss proper use of the Threshold Suspend feature with your healthcare provider.
