Libre2 parameters

[Nisa]

Hi - I’ve been wearing a trial Libre2 and have just changed it for my first purchase I am just wondering what parameters others have set - I’ve gone or targets of 4 - 8.5 I know it’s personal choice but just wondered what others users have as their target?

I have set my low alert higher so I can treat it before I go hypo.
My low is set at 4.5.

Good idea thank you

4.5 & 10. The high is a recent increase following a suggestion in another thread where a chap said he never corrects under 10. I must say it's working quite well. I would get alarms saying I was over say 8, so what? Do I consider an adjustment, or recognise that that is the likely curve for recent carbs, and still some IOB. That still happens at 10, just not so often.

YMMV

My "target" range is set for 3.9-10.0 but my alarms are set for the low at 4.5 and high is 12.0 xx

Target range and alarms are 2 different things and your settings may depend on different factors.
I think the factory setting range of 3.9 - 10 is suitable for everyone really. I know that type 2s are aiming to keep below 8.5 but non diabetic people go above 8.5 sometimes so I think 10 is a realistic upper level. As a diet and/or oral meds controlled Type 2 you might want to set the alarm at 8.5 just so that you can make a mental note that the last meal you had may have been a bit carb heavy. I would be setting the lower alarm at 3.5 or lower or not setting a lower alarm at all in that scenario if that is possible (I haven't got the Libre 2 yet so I am not sure if you can set one alarm but not the other) because you don't need it going off accidentally and disturbing your sleep when there is no concern of you going too low. If you are on insulin then obviously the low alarm is useful. 4.5 seems to be a good suggestion for the low level alarm if you need it. I might be inclined to set my upper alarm at 9 because being on a low carb diet I often need to correct after a meal for protein and 9 would give me enough time to stick a unit or two of Fiasp in and stop me breaching 10.

It really all comes down to your personal circumstances and diabetes and what you want to gain from it.

I will say that the Time in Range is one of the most useful features of the Libre system and gives you so much more attainable targets and therefore a positive mental impact but if you set your levels too tight then you might be undermining that positive aspect. Obviously we all want to do as well as possible but achieving minimum goals and being inspired to aim higher is far better better than having a tight target and maybe only achieving it one day out of 3 which can be pretty demotivating, especially if you are trying really hard. Not sure if that makes sense, hopefully it does.

@rebrascora yes you can switch one alarm off without it effecting the other, I had to the night I applied my last one as it was alarming and reading 2.9 when I was in the 8's and I needed some sleep lol xx

I haven't got the Libre 2 yet so I am not sure if you can set one alarm but not the other

Yes, you can set the high and the low glucose alarms independently of each other, and choose whether you have the 'lost bluetooth signal' alarm on or off as well. I never bother with the high glucose alarm, and I switched off the low alarm the other night, when my new sensor was being silly and reading 2.9 consistently.
Edit. @Kaylz types faster than I do! I wonder why it likes 2.9 so much.

Have to admit I had the same thought when I read your post in the waking thread, this one is consistently off bloods though but honestly can't be bothered reporting it as reported 3 in the last month xx

Funnily enough, mine had a flight to accuracy as soon as it heard me threaten it with Abbott, it still wasn't as reliable as I’d like it, but it’ll do, and four days in, it’s improved a bit more.

I have my low set at 5 as I can’t always leave classroom so it gives me warning I may need a sweet or little snack depending on the arrow and time to get cover if I need it. Higher is set to 10.

Currently 4.5 to 8.5

My Libre2 should arrive in a few days as an upgrade by health board, after 9 months and three scanners for Libre1. I was also considering what alarm settings to use - probably leave target range as suggested by DSN.
Think I'll initially set lower alarm limit to 5.0. Theory is I can have a snackette to provide a small correction rather than a larger correction which may cause a spike. It's also the minimum level for driving. But may have to adjust if too many alarms. Unsure of upper alarm level as I tend to spike so may set it something over 10 or switch off.

My low is set at 4.5, so as said by a couple of people above it gives me a chance to correct before going too low. My high is set at 6.9. I recognise that is quite low for a high. I chose that level, so again I can see what's happening and correct things (maybe a little extra insulin or some exercise) before I go above 8. Some may think this kid a bit extreme. I'd suggest experimenting to find out what works for you, according to what level you want your glucose levels to be between.
