If you have never used a hybrid closed loop system, which of the below potential benefits of these systems would be most important to you?

While I use a Dex G6 (with calibrations) I do pretty well with cheap MDI and low carb eating. Barring the crazy cost of pumps and the nightmare scenarios I hear very often with pumps – I could never trust a cgm to be accurate enough to give me the correct dosages using closed loop. They do sound great in theory to have less thinking in maintaining normal bg levels.
There are several items I would have checked with the question if that had been an option offered. Omnipod 5 received FDA approval on Friday and I plan to get one as soon as possible. I would like to wait until the Dexcom 7 is approved though. I like the smaller size of the 7 over the 6. I presently use Libre which I love for its size.
Thanks for the information that Omnipod 5 was approved! Exciting news!
Add no nighttime alarms!
Please define “hybrid closed loop system.” I’m not sure exactly what that means. I checked the “N/A” answer because I think I may have a hybrid closed loop system. I use the Dexcom G6 Control IQ system with a Tandem insulin pump. Is that a hybrid closed loop system?
Yes, it is.
I..have..never..heard..the..term..”Hybrid..closed..system..loop”
It’s where a cgm reports to a pump and it automates your insulin accordingly
I use a hybrid closed loop system and All of the Above benefits are why I use it.
I use a HCLS, with Dexcom’g6 and Tandem X2 pump on BIQ. CIQ doesn’t fit in with my T1D mgt style/goals. My preferred range is 60-120, and will correct (albeit minimally at 120 if I have no IOB and the trend arrow is upward) I cannot wait for a predicted bg of 160-180 for the pup to take actions. The target bg too high, the trigger for the system to react regarding high bg/predicting a high bg isn’t tight enough for me. I also make a lot of use of the temp basal functions (in both directions: increases or decreases) so I would miss that.
If you wanted to correct at a lower blood glucose level than 160-180, just set your high alarm at a lower level. Then you can give yourself a correction bolus at the lower level. That is what I do.
I have a distaste at allowing a computer to monitor and control my health and wellbeing – Never can a guarantee be provided that a closed loop system will never go awry…. Not willing to take the chance, and will continue relying on my own diligence.
I chose “none of the above” because I have tried a loop system but it did not benefit me. I wish “other” had been an option, as it would have been more fitting.
Because I already use the hybrid closed loop system, I answered N/A. I must say how surprised I am that more people who aren’t on a system didn’t say avoiding low or severe low blood sugars. I really thought that low blood sugars were such a big problem with diabetics that people would really want to avoid those low numbers. I know getting a CGM and a pump to lower my basal when I want to and also having the pump shut off to avoid low blood sugars were my main reasons for starting a hybrid system.
Most important to me was close control of Bgs while sleeping. I used the Medtronic closed loop system for several years. Because it’s sensor was so inaccurate, and it’s algorithm so frustrating, I usually woke up with Bgs over 150. When I tried to discuss it with Medtronic, the response I got was “150 is within range”. I finally gave up on closed loop and switched to Dexcom sensor and am so much happier. My nightly Bg control is better without the closed loop. I want to get back to a closed loop system, but I’m waiting to see next round of releases from Medtronic, Omnipod, and Dexcom before deciding what pump to get next.
I would want everything to be undercontoll.
