The most usual cause for insulin pump problems quoted by reps and DSNs is the infusion part of the system, so kinked cannulas, or repeated use of used sites etc.
My plan worked out with my DSN (as all patients and DSN really need to do) is to
change the infusion set.
After doing this and a correction dose if need be I wait 2 hours and re-test my BSL.
If it is coming down but slowly I may add in more correction,
if the BSL has gone up further and ketones are up, I change the infusion set once again, re-do the correction dose plus at least 30%- 40 % whilst I continue to sort out other possible causes like:
?could insulin have been frozen ? or exposed to >30 C, out of the fridge > 30 days (see pamphlet in the insulin box).
? get new insulin script?,
is there an error code on the pump?
can I see that the pump is actually working ?(I disconnect the tubing from the infusion site and run a 'test bolus' through),
also with high BSLs and ketones added in sometimes my insulin resistance increases and a 'usual' correction' dose
is not enough, and do
I increase usual bolus and basal doses as well (yes, I see you have done that with your basal))
Any sign of infection ? teeth, skin. urine ? tummy or cold virus? ? cycles? ? stress
My DSN and I also worked out a 'last ditch before hospital' plan which was to give small doses of intramuscular short-acting insulin, which works much quicker than under the skin doses to see if that will stop the rise. That plan however requires close co-ordination with my DSN, my ability to give myself an I.M. injection and having the syringe and length of needle to do so.
I hope your troubles settle easily and quickly (and that your DSN replies soon).
