Sensor Fail

Well last night was hell.

My sensor kept insisting I was low.  To the point of suspending my insulin.  Multiple tests showed me that no, I was actually fine (the lowest test I saw was about 5.4 mmol/L).  I phoned the Medtronic helpline at about 2am.  We troubleshooted some stuff and I thought we had fixed the issue.  So I went to sleep.

I woke up around 8am to more alarms.  My pump had lost contact with the sensor.  I got it all talking again, then went back to sleep.

Around 10am, the sensor suspended my pump's insulin yet again.  I guess I was so exhausted that I slept through the alerts for about an hour before finally waking up.  I called Medtronic again, but was told they're super busy and will call me back as soon as possible.

Around that time, I thought the sensor started working.  But no, it swung to saying I was too high (like in the 17-18 mmol/L range all afternoon).  Once again, blood tests revealed that no, I was not that high (more in the 11 mmol/L range).

So about a half hour ago, Medtronic got back to me.  They told me to pull the sensor and try a new one.  I took a picture of the old one to remember how the tape should look (and added it to a new page I just made called "Hints" so I'll easily be able to find it again).

The "doughnut" tape placement kind of confused me without this pic.

I once again used the inserter-thingy.  I'm a bit worried that the new sensor is going to fail as well - it hurt a bit at insertion and looks a bit bloody.  But I guess we'll see what happens in a few hours.

And hopefully I'll actually be able to sleep more tonight!!!!
