To begin with published June 4, 2018.

Medtronic's new 670G organisation for managing diabetes is galvanising, indeed: it combines an insulin heart and CGM (round-the-clock glucose monitor) with an algorithm to keep glucose in range. IT's dubbed a "hybrid closed loop" because it has both Motorcar and Manual Modes, but it is essentially the first loop of what an Artificial Pancreas volition eventually look like.

As a first-generation product, information technology is tricky to navigate for galore new users. We've been fortunate to talk with a number of tech compass PWDs (people with diabetes), including a few World Health Organization work in the diabetes industriousness, to gather this rather detailed list of tips. These are not the "official" recommendations you'll hear from the manufacturer, but rather proper-domain practical tips that get straight from the mouth of those World Health Organization've secondhand this new Minimed system.

If you're victimisation or considering the 670G, you Crataegus laevigata want to print verboten this guide:

Calibrations: willing, unmoving… make it bring on!

  • Do 3-4 calibrations per day to optimize your sensor readings. That is, go ahead and make all the extra fingerstick BG (blood sugar) checks you do every day anyway, and be sure to enter them A calibrations until you devi to the lowest degree 3-4 in.
  • Sometimes the pump nonsensically asks for a confirmatory 'BG' to nag you even when you're pretty sure IT's not needed. Don't skitter this — go ahead and enter a calibration to help improve the sensor readings.

Hand-operated vs. Machine Mode:

When you gear on the 670G, in that location's an initial 7-day period where you learn to conversion from Manual of arms Mode to Auto Mode. You should attempt to optimize your basal rates during this period. Also be aware:

  • On the 670G you can use a Temporary worker Basal in Manual Mode but not in Auto Mode, where a Suspend Insulin Delivery on Low (which can't be regular) is the only option.
  • If you revert to Manual Musical mode after being in Auto Mode for few time, you may need to change your I:C Ratio to a higher, i.e. less aggressive, number to prevent lows (see below).

Insulin-to-Carb Ratios:

  • Your Insulin-to-Carb (I:C) Ratio will be many aggressive when using the 670. So when you stimulation your frame-up in Manual Mode the first calendar week, disagreeable decreasing your I:C Ratio by 1-2 points. For example, if your normal I:C Ratio is 10, drop that number to either 8 or 9 in your young pump apparatus.

Basal Rates:

Your "Total Daily Basal Dose" goes down in Machine Mode, in part because IT is programmed to decrease your Auto Basal to aggressively defend against hypos. The decrease may also flow from in part to:

  • the more aggressive I:C Ratio
  • the fact that many users stimulation "fake carbs" to cause their BG down from the discipline target of 150mg/dL to the planned Auto Basal target of 120mg/dL, and
  • the more you depend on "shammer carb" boluses to redirect corrections retired to 120mg/dL, the less need in that location is for Auto Basal to facilitate these corrections

Insulin Action:

The normal heart setting for insulin sue time is usually 4 hours, but with the 670G, IT will probably decline to 3 to 3.5 hours. Be aware of this when inputting your setup. Specifically, the insulin military action on prior pumps is typically set at:

  • 4 hours for adult PWDs with normal insulin predisposition
  • 5-6 hours for medical specialty PWDs or elderly type 1 PWDs who are insulin sensitive
  • 3 hours or less for insulin-resistant PWDs

Manipulation Exercise:

As noted, the 670G bequeath aggressively defend against hypoglycemia while in Auto Mode. If you are using Manual Mode most of the time, a shift to Auto Mode will accommodate mild to moderate upticks in activity without a need to change your target BG from 120 to 150mg/decilitre.

For strenuous action, you Crataegus laevigata need to change the BG target in Auto Mode to 150mg/dL and supplement with carbs.

Confirmation BGs:

  • Confirmations are requested when your BG exceeds low or high targets, or if you've been at your max or minimum Auto Basal Rate for more 2.5 hours while in Car Mode.
  • Timely pre-repast boluses for meals and snacks will decrease high BGs and minimize the time your Auto Basal is parked at the maximum rate.
  • Correcting your BG to ≤120mg/dL with "fake carbs" leave put Auto Essential at its nominal and may cause the need for more check BGs. Retributory so you love!

One of our contributors to this list in reality told United States of America: "I've over that being able to avoid frequent hypos is worth the hassle of managing each the alerts and over-notifications."

Hope this helps!
