Yesterday morning I was woken up by my pump/cgm alarm warning me of low blood sugar. I cleared the alarm and then saw an active insulin delivery screen showing 4.5units out of a 10unit bolus had so far been delivered. I hastily disconnected everything.
The first time I knowingly touched my pump was to clear the alarm yet somehow 1 minute earlier I had selected a 10u bolus with a blood sugar of 3.7. I cannot comprehend how I managed this action, 10 units is more than I bolus in a day.
I checked with Medtronic and the only explanation was that I must have somehow done this myself.
I have never given the maximum bolus setting on my pump a thought. On checking, it was set at 10 units, about 6 units more than I ever bolus for any meal. Last night I reduced it to 0.1u and also locked the keys for safety sake.
Has anybody else managed to operate a pump without any recollection. I am still a nervous gibbering wreck today after considering the potential for disaster if I had not cleared the alarm when I did and noticed the active insulin delivery screen.
I have managed a similar through sleepy button pressing. I had been struggling with lows at the start of the night and taken on multiple doses of fast acting sugar. Eventually my blood sugars started to behave themselves and I settled down to get some sleep. Once asleep I somehow managed to to put my temp basal rate to 0% for 2 hours, the resulting blood sugar was not pretty!
Yes, I have. I lazily press the buttons on my pump through my clothing to turn off alarms to bolus for meals or to do a blood sugar. If I press too many times, which I have done whilst low, or when I think it hasn’t canceled, I have bolused by accident. Usually though, the pump beep beep beeps to tell me I haven’t finished a bolus, which alerts me to the fact that I was about to give myself a surprise one! Perhaps in your low state you heard the cgm alarm and thought it was an alarm for something else and tried to cancel it but gave yourself a bolus instead?
Does your pump not have a “Lock keyboard” function? On the Medtronic Veo, it’s an option under “Utilities” and means you have to press two buttons together to unlock the pump so it would be virtually impossible to bolus in your sleep.
My daily totals vary from 25 to 35 depending on how much I’m eating/exercising/hormone levels etc.
I can lock my pump, but I dont, because when I had a loan pump to try at the beginning, I managed to lock it then couldnt unlock it at all. Had to remove the batteries and leave for 20 mins so it reset the lock. So I’m petrified it would do that when I needed it – so I dont lock it. Never managed to turn anything on in my sleep, although I wouldnt put it past me (I have managed to feed myself in my sleep, whilst hypo, didnt wake up, next morning, found evidence, but no high bg, so must have been hypo…)
