The meter to pump communication resets the timer with the Ping system, it was activated when we did my initial pump setup, I believe mine is 14 or 15 hours.
Which would or wouldn't include blood sugar checking on the meter/remote? My manual doesn't mention this at all!
A typical night for me might be eat at 7, check blood sugar at 9 and correct if high otherwise not. Check at bedtime - same thing. So if let's say I bolused at 7, checked my blood sugar at 9 and at midnight or 1AM and both times it was fine, the last "button pushing" (other than checking blood sugar) would have been at 7 - so I would definitely have gone 12 hours without pushing buttons. I know you can set it for longer periods, but I think the longer the period, the less the chance of catching a dangerous low in the crucial window.
So, does blood sugar checking count as meter to pump communication? That would make it more meaningful to use.
I assume all of the pumps alert you before it turns off. My Medtronic does. Maybe you should try setting it to 1 hour if you want to test it out.
Good suggestion, Sam!
Meter readings and boluses from the remote count towards the usage timer based on my experience, I've gone a full 3 days between site changes without touching my pump and didn't have the alarm go off.
I believe you, Clayton, but just had the opposite experience! I decided to go for it and set my auto remote to 12 hours. I bolused for dinner last night at 7:54. I then tested from my Ping meter/remote several times before I went to bed at 2:30. I was awakened this morning at 8:30 by the alarm and had no delivery. I had actually heard it in my sleep and ignored it earlier. (I just assume some tech thing somewhere is singing to me when I hear electronic sounds). I am guessing that was probably after 7:54 though it felt earlier.
So that means at least that the testing from the meter doesn't count towards the 12 hours.
It's entirely possible B.S. readings don't count, my experience is with a larger window (15 hrs) with auto-off where I've only had it go off on like 3 occasions where I was going into a day off, ate early and had bolused at like 5-6 and slept in until 9.
Mine would probably go off too often set at 12 hours, I tend to eat most evenings at around 6 and don't have to be up until almost 7. Would drive myself nuts if I had it set to a 12 hour timer.
Yep, 12 hours definitely is too short a time period. Being awakened by an alarm and no delivery/pump not primed and having to jump out of bed and re-do my set (and be high!) is not my idea of a nice morning. I have no idea how the people cgm's can stand all that alarming!
I just turned mine to off. Even 15 hours could get me occasionally - I've been known to eat dinner at 7 and then stay up late and sleep till 10. And for me, I just think it's too random. If I went low during my sleep, it would probably be within that 15 hour window and hopefully my liver would kick in and wake me.
I'd actually like to know the percentage of the time that happens - I've only been unconscious once and my liver kicked in and I was able to treat. I doubt that there are statistics on that but it sure would be nice to know. Just based on reports on here it feels like it's more often than not, which is good.
I was wondering about the usefulness of auto-off a while ago. I stumbled upon an article in the Seattle Times about a young pregnant woman who suffered brain damage and lost her pregnancy due to insulin shock. She was discovered 3 days later, still alive, with the pump still running. Here family won a $5 million settlement. It sounds like a big part of the case against Medtronic was that the pump trainer hadn't activated Auto-Off.
I hesitate to link to the original article, because it is very upsetting.
My auto-off is set for 14 hours. During those times when I have had an early dinner,slept in, and had a late breakfast on generally active weekends, my pump has shut down. There are times that I may not bolus for 14 hours. When I am active and not eating much, I have already set my basals low ( temporary rate),so I really do not need to touch it(the pump) unless I am bolussing and eating.( of course this is when I am not wearing the CGM)
As said before, The pump automatically shuts off after whatever length of time without button pushing, that the user sets it. though I set mine, I really think I just did it because it was there... It is beyond me why that feature is necessary since MM Pump models currently available in the U.S. cannot react to low BG info from the CGMS,or transmitted to the pump from a meter.
As SAMIAM wrote: "I have yet to hear about a single case of someone surviving due to Auto-Off."
I have my MM set on, for 12 hours.
I think of it like a seat belt. Always use it, 'just in case'..
I wonder if when meter BG is sent via link, if that counts as a button press ??.
