Possible Dangerous Situation MM 712

[PepsiLvr]

Last night I changed my reservoir and primed my pump. All was well and good. However, this morning I woke up and saw my screen said "10.4 units" The pump was STILL IN PRIME MODE.

Granted, it's my fault for forgetting to push "ESC" to exit prime mode but here is what happened and what could have happened

1) I did not get my basil all night and woke up with high BG.
2) I'm glad I didn't lay wrong on my pump and accidentally hit the ACT button or I would have had a serious overdose with no limit on the number of units I could have received since priming does not have a limit like the bolus limit you can set.

This is the first time I "forgot" to exit prime mode but I'm just glad the only thing that happened was my BG was high.

I would have thought there would be some kind of alarm or auto-exit or auto-off for not leaving prime mode in, say, 5 minutes.

Just wanted to make everyone aware.

That WAS my biggest safety complaint with their pumps. However, a while back on here we discovered that they finally changed that deadly (in my opinion) mistake on the x22 model. I can't believe that that pump made it past the FDA because of that. But it is fixed on the X22 models

[PepsiLvr]

I'm glad it's fixed now. I guess I should have searched better before posting. I'm surprised they didn't have to recall them or at least take some, ahem, corporate responsibility and do a voluntary recall. As far as the FDA goes, I'm not surprised after what else has made it through.

I've still done it though. I don't always here my beeps. I've gone a couple of hours a few times.

I have done it at least three times. Caught it once early and twice went through the entire night without a basal dose of insulin. Blood sugar in the 400-500 range. I may call MiniMed and do an upgrade from my 715 to 722. I am surprised it is fixed in the 722 model. I was told several times by MiniMed that the only difference in the two pumps was the software for CGMS.

I have forgotten this as well, but thanks to the alert on the pump to remind me I am still in "Load" mode it has not caused any problems.

[fgummett]

Not sure if is the same thing but the 712 would allow you to skip over the fixed prime step where the 722 will not and remains in an alert (black circle) state until you have competed the fixed prime after a prime.

I am usually pretty relaxed with the common ideas of going over like doubling doses with MDI, the small chance of fluking a bolus when rolling around in bed, etc but I have to say you gave me literal shivers with this statement. Take care 712 users.

I cannot use the alarm system because I am hard of hearing, especially with the high frequency sounds. I have to used the vibration notifier but that is no good if it is not attached to my body. Any time the pump is not attached to me I have no way of knowing if it vibrates. Nothing serious so far but it could be someday.

Problem with the 712 and 715 is it doesn't alarm at all. It just blinks at you all night in a sort of suspend mode.

Not sure what you mean here. I don't usually do a fixed prime after a manual prime.

[PepsiLvr]

I called MM to see what they had to say and the lady said the 512 (smaller 712) just goes to a blank MM screen with the black circles. She didn't believe me that the 712 didn't. She tried it on a 712 and now understands what I was talking about. I guess the 512 and 712 have some variation in the software.

Anyway, she really didn't show any concern and further asserted it was my fault for not priming correctly. Yes, it was my fault and that's what I told her at the beginning of the call. I didn't finish priming. My problem was that it is their fault for allowing a dangerous condition to exist. She even claimed that upgraded pumps work te same way thus contradicting herself with the 512 / 712 comparison she just made. I know others have said it is fixed though. I just told her I would look into other vendors for my next pump since MM doesn't have a concern for my safety.

With the MM pumps... the manual prime is run off the body to fill the tubing. Then they offer a small fixed prime once you have reconnected... just enough to fill the sub-cutaneous tubing... assuming you have just replaced that as well.

Huh, I don't think mine says anything about a fixed prime after I do a manual prime. If I want to do a manual prime, I go in later and select it from the menu. Maybe next time I'll see if it mentions it, but I don't think so.

Wow is about all I can say. I'm with you all the way and find her arguments and attitude offensive, unprofessional and downright negligent.

Not sure what you mean here. I don't usually do a fixed prime after a manual prime.

The manual prime is to fill the line, the fixed is to fill the cannula. If you don't do a fixed prime, it means the first wack of insulin that goes in will be filling the cannula, not you.

This may or may not be of consequence to you: but you should be aware of it. Some people like me find it useful to over fixed-prime, to get a new cannula "kick started" faster.

Edit: sorry, missed fgummet's comment to the same effect. True this might be a difference between pumps.

I don't change my tubing and set at the same time, so I don't need to do a fixed prime after a manual prime. The part that's confusing me is where they said that you can't skip that. I always skip it.

On my 722 (same on 712 as I recall) under Menu->Prime, the first option is "Fixed Prime"... this is set according to the infusion set that you use... mine is on 0.7u
Each time I do a Manual Prime and finish with Esc.. the next thing offered is Fixed Prime. With the 712 I could just escape out of it (if I was reusing an infusion set) but with the 722 I was warned you cannot skip it... so if need be I just run it still disconnected. Perhaps if I did not set a value in the Menu->Prime->Fixed Prime option it would not come up?

Huh. I'm looking at the manual for the 522/722 and it just says to select Fixed Prime from the menu after you've done the Manual Prime. My Fixed Prime value defaults to whatever I used last and my pump still doesn't make me do it after a Manual Prime.

[Subby]

Ah I see lilituc... silly me. I was thinking it was a bit weird you pumping that long and not realising the use of a fixed prime. (Although I suppose it could happen).

Fgummett, I run a 722 and I can escape out after a manual prime with no fixed prime, no problems.

[fgummett]

Thanks... it was my "pump nurse" who warned me about this... I see her tomorrow so I'll ask her what she meant.
