Sorry that you’ve had such a rough start to your MM780 journey Sue.

Hopefully with your old bolus pattern and ratios copied across things will be a little easier - can you see if there was a difference to your TDD between the two pumps?

FWIW I can see some people on the tSlim group needing to make changes to their established settings - so perhaps you will end up with just an upward tweak on things?

Thanks Mike

That is interesting with the t-slim info with the need for some changes. It is also encouraging to pick up that the automated systems can eliminate the need for pen corrections, but good to be armed with a solution to tell the pump what I have done.

I copied the Basal rates and ratios across, but I think my automated responses to things with the Combo were masking some things that needed changing. I also got into a bit of a loop and didn’t just change rates, as I would have done on the Combo, and didn’t know what questions to ask.

Using this quiet time to be a lot more systematic in checking things whilst in the Combo, try out cannula when not using with the pump, .... Being logical and recording again. I had become a bit complacent possibly.

A new start planned in the new year armed with lots more (accurate) info gleaned from the Combo, and then no doubt a bit more tweaking once I try the switch again.

the quicksets they started me on were very patchy and I many many site failures.

Have the same problem after I changed over to them from the angled sets.

Personally I think you are over thinking things 🙂 Take a nice big deep breath and relax. Just put your old pump setting into the new one and tweak from there. Yes I had to tweak a bit but nothing horrendous.

Quick question Sue what infusion set are you using, I have Mini Med Mio Advance and they seem to work fine, I don’t remember the name of the ones I started with but I remember they were a pain

Back of the packet might be more useful

Are there any Medtronic users who can help me?

Hey SB the 670G doesn’t have any comparable features, I have adjusted the “Active insulin time” to 2.5 hours after some experiments and everything thing is fine, this could be something for you to experiment with, I think the default is 4 hours, verify the active insulin time from the info sheet of insulin you are using and pop that figure into the parameter
Options > Delivery Settings > Bolus Estimate setup > Active Insulin Time

In manual mode i would always just bolus from the pump bolus wizard if I needed a bit extra insulin, the wizard will calculate what insulin you have active and just use a small carb number something like 10g that way the pump knows what insulin you are taking, it will show you the units it will deliver so you can confirm it first, you can go back and adjust the carb amount if it going to deliver too much or too little units.

the pump needs as much info about your habits while in manual mode so it can work correctly in Auto mode, it uses the last Six days of data to improve your current BG levels so I would avoid “topping up” from a pen if you can

Thanks @Paulbreen and @Pumper_Sue

I always overthink things and want to have things clear in my head. I doubt I will change that much now Sue. I was disconcerted as I did exactly what you suggested transferring my rates and ratios straight over, and things went bonkers. Still not sure why, although today a UTI has shown itself so that may have been brewing or it could be as a result of having such high Bgs for so long. .

I (briefly) used the Minimed mio advanced @Paulbreen but have also got a few that go with the reusable serter , as I would like to avoid the amount of waste. I shall stick one of each in over the next few days and just check I am not reacting to the glue or the ‘needle’ .

The linked BG test kit finally arrived today so that is another piece of the jigsaw sorted. I am happy on my old pump for a while and will start again in the new year, having checked basal rates etc.

Thanks for all the ideas and support.

Might be worth trying some different infusion sets too? Took me a while to find an infusion site that worked for me - the quicksets they started me on were very patchy and I many many site failures

That’s useful to know Mike.

I now have a couple of different sets to try and they are happy to send me others if I want to try them, but need to go through the DSN, who is not back until January. I think I had a variety of things that didn’t quite work for me in that first week and I just lost confidence. It was good to step away from it, and I am happy to return to it when DSN is around.

@Paulbreen please have a read of this article Why DIA values are wrong | Diabettech - Diabetes and Technology it will help you understand IOB/DIA or what ever you want to call it.

There is no insulin on the market with such a short DIA value so you are potentially overdosing on your bolus insulin and could come a cropper one day big time. If I were you I would be doing some very basic basal testing.

I use Fiasp in my pump and duration is set to 5 hours which works very well.

Thanks Sue for pointing that out and I looked at the article you attached. Makes interesting reading but I would have a concern that there is no author listed apart from “admin” I wonder who is admin and how they are qualified to create such an article.
Also I have not had an hypo of less than 3.8 in the last 2 years since I started using this pump.
In Germany when you start using a “ loop type system” you go to a specialist diabetic hospital for 10 days so they can train you in the use of the pump and you spend 7-8 days in manual mode then 2 more days with the pump in auto mode verifying the pump is working with you as expected. Also they monitor your BG every 2 hours day and night for the duration of your stay so they are able to provide a very clear picture of how your body is reacting to your insulin.
all insulin’s react differently with different individuals and I can guarantee that novarapid or Fisap is not present in my body after 5 hours. Maybe that may change in the future and I would pick up on it with my team but as it stands 2.5 hrs suits me very well at the moment. I was also not making any recommendations to SB2015 to change anything without input from here trainers and support team only giving pointers from my experiences with the Meditronic 670G+CGM

About | Diabettech - Diabetes and Technology info for you and the author is called Tim 🙂 Have a read of pumping insulin as well. People tend to confuse peak of insulin and duration which I think is what you are doing.

 

[SB2015]

Thanks both.

I am happy to be directed to any info, and also hear of other people’s experiences, to draw on.
This can all feed in to the decisions I will make, and then work with DSN if necessary.
The loop start in Germany sounds very well supported.

Hi Sue I took another look at the Diabettec site as you suggested and there is some interesting reading but it’s just a forum type site with no medical foundation to the contributions.
I do enjoy reading this kind of thing but I wouldn’t base my own treatment on it, to arrive at my figure of 2.5 hours it was done with the specialist nurses who trained me to use the pump and Meditronic Nurse. I sort of have to disagree with your diagnosis as I don’t have any hypo issues, in fact I am around 93-95% TIR and the out of range seems to happen when I change a sensor or when I over indulge with dinner sometimes

It is always interesting to read how different the advice is, and as with al things Diabetic, we each have to find our way through and find out what works for us.

Very wise words Sue, sharing experiences is a great pathway for everyone

It’s Tim Street. Well known on Twitter and a really nice guy (I’ve met him a few times). Quite well thought of in the Loop/APS community and as far as I can tell he finances most of his kit himself rather than being offered it as a freebie by the manufacturer.

 

[Paulbreen]

Thanks Mike, the articles are interesting and I do love a good techie as it’s my world for work, I do have a big interest in the loop world myself but I prefer to dabble in it quietly mainly for my own amusement
