Changed to Omnipod from 640g - hypo central!

Hi @sophc I have no experience with the Omnipod BUT I will tag @Mel dCP who is pretty upto date with it
Hope you get it sorted pretty quick. Have you spoke to your DSN about what is happening?

Hi @sophc I'll tag a couple of other pump users in case they can shed some light on this @tim2000s @himtoo

Hi @sophc, Sorry to hear that you are having these teething troubles.!!
Whilst I don''t use an Omnipod pump, what I did was use some graph paper and put in the angles and lengths of cannula you mentioned:
......................30 degrees, 13 mm --> 6.5 mm depth. and if you had managed
......................20 degrees, 13 mm --> 5 mm
......................45 degrees, 6 mm --> 4.5 mm depth and if the Omnipod was tilted a bit to say 5 degrees
......................50degrees , 6 mm --> 5 mm depth.
But when a cannula is fired in maybe it goes deeper to begin with and if that goes through the layer between subcutaneous tissue (where you wish the tip to be) and the muscle. Could the insulin then be being partly absorbed by going through a hole in the layer between into the the muscle giving quicker absorption of insulin and thus hypos?
But the 'graph paper' depth of 4.5 mm is smaller than most cannula depths. And with the 13 mm cannula would not you be at greater risk of going through into muscle?
Did your DSN suggest any changes to help ease the hypos ? lower the basal rate and other settings ??
Could it be that the Medtronic settings were unknowingly being adjusted for some ?inaccuracy in the dosing and thus on the new pump the 'Medtronic doses' are now too high?
Given there does not seem to be much one can do to change the cannula depth would your DSN agree to at least trying to prevent the hypos with appropriate dosage changes and then see how things go ??
Best Wishes and fingers crossed and hugs !!!

Thanks for the tag, I can honestly admit that I’m zero help here - I’ve only ever had the Omnipod, so have nothing to compare it to. Also, I’m far from lean

When I switched to Omnipod I found I needed to back my basal rates down a little. I switched from a Medtronic pump to a pod. After basal testing, the basal rates on the Omnipod just push more insulin. I don’t know why, but you’ll just have to learn and adjust to it.

Angle of infusion set shouldn’t mean anything to blood sugar. Amount of insulin delivered would.

Hi @sophc,
Are you winning?

hi @sophc
i have read ( but have no actual firsthand experience ) from others reporting this phenomenon when changing pump ... so perhaps some further basal rate testing is required to get your rates correct on the omnipod

have you discussed with your diabetic nurse ??

@sophc - the mechanisms used by different pumps for delivering insulin affect what the output is. What most people don't realise is that when you change pumps, you usually have to change basal rates as the amounts they push out are all slightly different. I'm afraid it is par for the course.

You'll need to go back and do an entirely new basal test. If you have a libre this will be a lot easier.
