NSHere’s my LOOPing update.  I’ve been running the RileyLink for about 8 weeks.  I started running it OPEN, which means that it is ON but not making and implementing decisions with my insulin pump, based on the algorithm and CGM and carb inputs.  After about 2 weeks, I CLOSED THE LOOP!  Just overnight!  It was exciting.  NOTHING BAD HAPPENED!  In fact, my blood sugars seemed to run flat all night, between 100 and 140.  A miracle.  The next few nights were more bouncy but still good.  I never had a low while running the OPEN loop. 

About 3 weeks ago, I decided that I needed to tweak my pump settings, which haven’t been re-evaluated since I started pumping over 14 years ago.  And I think I may have entered some wrong settings when I was setting up basals on a new pump (I mean, really, how can my I:C ratio exactly equal my Insulin Sensitivity?!?!).  So I’ve been basal and ratio testing.  After all, GIGO (garbage in, garbage out) … I need to be sure the LOOP has as accurate settings as possible. 

I expect to CLOSE the loop soon … just running it CLOSED sometimes through the night. 

My take on using the CLOSED loop so far:

  • It’s safe!
  • It’s interesting to see how many corrections it makes throughout a 24 hour period
  • Seeing my data on Nightscout is a WEALTH of information.  THANK YOU, Nightscout folks for all the hard work you’ve given to make our lives better, using our own data!  #WeAreNotWaiting.

More to come on how to test your settings.
