780 Users

It is important that you have your targets set in your bolus calculator, as you have shown us @jessd1.these will apply for your boluses when you are in manual mode, along with your sensitivity factors and also your basal profiles, which would have been set up with your team during your training.

When you switch into Smarthuard, the looping system, you get to choose a target of 5.5, 6.1 or 6.7
It would be worth you asking your team about which of these to use at present. Once this is set the automated corrections works to get you back to this target value. Not an instant change but one that the algorithm is constantly working towards. It took me some time to get in my head which settings were used when. I change my Smartguard target at times to suit other changes such as changes in meds.

Let us know how you get on.
 
Hi I’ve been using 780 for about 6 months. Hard initially but now my overall BG is within range and I’ve lost over a stone in weight. No change in diet think it must be due to trickle background feed of insulin. I now have a question ! I cannot find any info re swimming I know pump will need to be suspended and removed feed suspended. How does swimming affect the feed connection in pool sea etc. Does the reader feed for pump fall of / need to be covered etc? Also does high temp if sunbathing have an affect.

Hi @heathero i took ages to pluck up the courage to swim again after drowning a pump. Our pumps are in theory waterproof but I had a tiny crack in mine so after an hours swimming I noticed it was no longer working. It was replaced but then I decided that I needed to take it off when swimming!!!
I disconnect, suspend all delivery (so it doesn’t think it is giving me insulin which I am not getting) I put the plug in the cannula, which seems to stay stuck, as it does when I have a long soak in the bath.
I have my pump at the end of the pool so when I want to check my levels I hang around at that end until the pump and sensor reconnect and tell me my levels I (thanks @helli ) I don’t put anything over the cannula or sensor, and just put a new one in afterwards if they look a bit unstuck.

I haven’t tried sunbathing, but the advice is to keep the pump out of direct sunlight. Not sure about the sensor but it may be the same for that.

Thanks for the info I have read you can buy adhesive patches to cover reader with in multiple packs £1 per patch. But unsure guess it’s like all equipment diabetics use we have to ‘ live and learn’. Yes I had read they’re waterproof but not sure if my pump insurance would cover water damage. I found with Omnipod didn’t like sea water and failed most times and reader sometimes. Yes pool idea good if safe environment. ( not too busy) Will try out initially in Jacuzzi at health spa.

In a jacuzzi I tend to keep the sensor out of the water and rest that arm on the side. It just seems too hot.
I bought some ‘Not Just a Patch’ but gave upon them as they were not particularly sticky. Also having switched to the Simplera Sync they are just like Libre and very sticky (so far).
As you say it is live and learn.

When I drowned my pump Medtronic just replaced it. I didn’t even think of involving my insurance. I had followed the info from Medtronic and assumed it was waterproof so I guess they were okay with it. I did find the crack afterwards. I think the more recent pumps are more robust.
 
A “what do you do when” question for other MM780 users…

I know how important it is to only give Deep Thought accurate information about carbs, and not to add in ‘fake carbs’ as a way of manually correcting. Because of the way the algorithm won’t be able to tell what you are up to…

But

What do you do when you know you’ve made a clear estimation error, and you’ve not asked for enough insulin. Do you just sit it out and wait for the algorithm to eventually bring down the inevitable rise, or do you fess up, and add a post-meal revised estimate of the carbs you missed with the meal estimate?

I had a family meal at my sister’s yesterday, and made a guesstimate for chilli, rice, garlic bread, and then a cheeky slice of passion fruit cheese cake. I was a little on the cautious side because I was driving afterwards… but once back home my levels started on the ole 45° incline into the 12s. I knew why this was happening, so added in the insulin I figured I’d under-dosed for the extra slice or two of garlic bread… Balanced out by bedtime.

What would you do in this situation?
 
Hi @everydayupsanddowns . Snap.

I went to do a talk for DUK last night and it included a meal. I definitely got my carbs wrong, and rose rather rapidly, as there were no doubt hidden sugars in there. I chose to out more carbs into the bolus calculator as I knew that the algorithm would not cope with the big discrepancy. I was conservative again as I was driving home, but wanted to reduce the work Hermione needed to do. I kept a watch once home, but once I got below 14 went to bed. Woke at a nice 5.5 and she had me level by 2:00 am. Not ideal but these days happen, and I ate stuff I would not normally, and probably won’t again for ages.

I hope that helps and that your levels settled down quickly.
 
Thanks @SB2015 - that's reassuring that you took the same approach.

Yep I was back down into single figures by bedtime, and woke in the mid 6s with no alerts, alarms of faff overnight 🙂
 
I've been on 780 and Sensor 4 for about three years (fully funded because of no glucose level awareness) and type 1 since 1956. I am beginning to love the 780, mainly because 95% I wake up 5.0-6.0 every morning and no night hypos at all. I always had big problems with blood sugar shooting up in the morning, but that's stopped because I stopped eating breakfast or having a bolus then. I have just water at 7.30 (with Clopidogrel 75mg once per day and DelofineXL 2.5mg (morning and again in evening. Atorvastatin in evening. I have a coffee at about 9.30am (because I like it) but nothing to eat between 8.00pm and 1.00 next day when I have about 20gms carb. I eat lots of different veg and salad and fish a couple of times a week. We grow quite a lot of our own fruit and veg on our allotment because it is so delicious. I stopped drinking alcohol about three years ago after having a glass of red wine every night for fifty years. Feel a bit better for it and no desire to start again. Haven't added salt to anything for 10 years, but have few salt laden crisps once every month or two.
I can check my blood sugar on my iphone and on the pump and see the variations for the last 24 hours. The pump tells you how much insulin is active, how much you have left, when you last bolused and averages over the last 24 hours, 7 days, 14 day and 30 days with % in range and total carbs, total boluses and total basal.
It isn't good at self-correcting during the day. My blood sugar has always gone up and down regardless of how many carbs. how much exercise, how much insulin, but the 780 doesn't automatically correct my high blood sugars enough to bring them down. They correct enough to keep the level at 12.5. You can't alter Medtronic's control algorithm, so I just give myself an extra bolus when I'm high by pretending I've eaten 10-15g of carb (which I haven't). This is very bad practice, but I am 87% in range over the last 14 days and haven't been below 82% for a year or two, after a lifetime of having to prick for blood tests 8 x a day to avoid calamity of high or low. Now I blood test only when I change the sensor (every seven days).
Diabetes is relentless but the 780 and Sensor 4 have just lightened the load enormously. You have to keep looking for patterns and working out why. I was very lucky to realise that I could eliminate hideous sugar level problems by not having breakfast or a bolus in the morning. Very important not to assume that things have to be the way they are.
 
So good to read how well the 780 is working for you @adamrit and that you have found workarounds for issues that have arisen by looking for patterns.

Like you I am regularly have a TIR in the 80s. I have found my post meal rises are generally sorted with the timing of my pre-bolus and as a consequence enjoy eating whatever I want at home. Not so good when eating out where I don’t know the carbs and cannot rely on the timing of a pre-bolus. However in the grand scheme of things I am very happy with the system.
