Epic Fail

If something stops working completely, that is a clear indication that something is wrong or it is broken.  But if something still functions, but gives incorrect data that looks feasible and correct, that is an epic fail. That is what happened last week with TD's Continuous Glucose Monitor (CGM), and I was not best pleased with that piece of technology.

Late Wednesday night/ early hours of Thursday morning, the CGM graph line looked astoundingly impressive.  The number were in the perfect zone (5 -6) and the line was steady, flat and consistent.  But then things took a dip for the worse, and TD's glucose plummeted to the 3s, then 2s  (so the graph told us later...) and finally when Andrew did the 6am reading, the display just said "LOW" i.e. no positive number at all.  That means that TD's glucose level was so low that she should have been unconscious or dead.  But she said she was feeling fine.  Talking is definitely a sign of being undead, so that was reassuring for us.  She ate Super Cs, and then she tested using the old fashioned way - by pricking her finger and testing the blood sample.  This reading said her glucose level was 12 - a little high, no doubt from those Super Cs.  We compared that reading to the new techno CGM.  It came up with 2.6.  You can see the problem - this is misinformation at its worst.  The sensor in her arm continued giving false readings all day, until TD decided to rip it out, as it was causing more worry than it was worth.  (And it is worth quite a lot - each sensor, which is supposed to last two weeks, costs just shy of R1K).

Symptoms of a severe glucose low (hypoglycemia)

We waited until the usual switch over day - Saturday - to replace the sensor, and touch wood, it seems to be working fine.  When it read 2.3 today at lunch time, TD really was horribly low, shaking, unable to function and felt awful.  It really was an emergency.

Sometimes I think we rely on technology too much.  TD's reason for delaying the use of technology and the CGM was so that she could learn to listen to her body more. And that has served her well.  She knew she wasn't low on Wednesday when the meter told her she was, and she knew today that she was in trouble, and for that I am very grateful.

It shook me up a bit.  We have to trust this technology to know what TD's body is doing, so malfunctions confuse me and knock confidence levels.  I needed to keep an eye on TD last Thursday - I didn't trust the universe at all that day.  It was a school free day (exams) so she and I had a quiet day here.

I wonder about my own life at times.  I need to function optimally - not display false readings of situations or misjudge which direction things are going.  Writing has become my old fashioned way of checking myself.  It is like fitting a working sensor. And new technology allows me to connect with a community.  Your reading my blog encourages me, and I thank you.
