are you filling the cannula correctly?
e.g a 9mm cannula takes .5 units to fill and if your basal is 1.5 per hour your gonna be that .5 short after that hour.
just a thought.
For the first year on the Omnipod this was never an issue but seems to have become a problem for my son in the last six months. We currently put him on an increased temp basal for 2 hrs after every pod change to halt the rise.
I have not got an Omnipod but if I had a high bg after inserting a new cannula, I would do a correction dose of insulin back to my target bg. My target is 6mmol so if my bg was 9mmol I would need a correction dose to cover 3mmol so that my bg returned back to my target.
Depends how high people go... my levels zoomed up to 20 guaranteed 99% of the time within 4 hours...
That is why you must get a way worked out for you, on your readings and correction figures...etc..
