Pump & Fiasp

[Ivostas66]

So I've just arrived home from my Omnipod 5 training - sounds like they are running morning and afternoon sessions currently to try to get through the backlog.

I raised a query with the Omnipod specialist and the DSN about 'tunnelling' - I posted recently about higher than normal BG for a couple of weeks and was finding that when removing the pump at the end of its cycle, my skin was wet with insulin, so it clearly wasn't entering my system effectively. Following advice on here, extending bolus if I was using more than around 6 units helped massively.

One of the other attendees said that they had been moved from Fiasp to Novorapid due to similar issues, and also the insulin occasionally crystallising in the pump.

The Omnipod specialist had never heard of this before. Initially they thought it was an injection site issue - but I rotate 6 areas of my body (upper arms, abdomen and lower back). She and the DSN stated that Fiasp is recommended for those injecting who find Novorapid too slow acting, that Novorapid is recommended for the Omnipod systems and that I should consider switching back to Novorapid "There's not really any need to use Fiasp when pumping. You aren't going to see the benefits of Fiasp that you were when injecting".

Anyone else encountered any issues with Fiasp & pumps?

Although I have not experienced issues pumping with Fiasp, I have heard that some people find Fiasp more "sticky" and it can "gum up" the pump.
As I say, not an issue I have had but certainly something I have heard from my DSN and read,

When it comes to benefits of using Fiasp with a pump, I have found it is very beneficial. Not only in terms of pre-bolusing but also in terms of the effect of changing basal. For example, I do not have to suspend my basal for exercise as early as I did with NovoRapid.
I do not have HCL but I have auto-suspend (basal suspends when BG is heading towards a hypo). Again the extra responsiveness and short activity period means this is more effective with Fiasp.

I've used Fiasp for years in my pump.
An 80/20 split is what I use for most meals any snacks then it's a straight bolus. I also make sure the set is changed bang on the 3 days, if not a bit sooner.
Look at the speed your insulin is pumped when doing a bolus. There's a fast and or normal (slower) bolus. Use the slower.

Been fiasp user for many years now all while using Omnipod pumps, currently using Omnipod 5 & not had any issues with fiasp insulin delivery or absorption.

Regards to fiasp being faster than novorapid, do find this is the case in pump, it works slightly faster than novo & doesn't hang around for as long in own experience.

The Omnipod specialist had never heard of this before.

I'm always a little suspicious when pros say this - I mean if we on the forum, with our modest experience and exposure all think "Ah yeah, that's a thing" then surely someone who does this for a living will have come across it?!?

Infusion sites are the weak link for sure. Had to swap my set early this evening because a day of chasing highs convinced me there was some sort of tunneling/malabsorption going on. 12 hours of BG chaos, and now everything meekly pootling as expected.

On the old tSlim I sometimes could rub the set sticky and smell the insulin at the site. I'm very careful with the Autosoft/Mio style self-serting sets now as I'm aware there's a point between initial tack-insertion and fully fixing the site where movement can happen, which I assume is where the tunneling begins.
