We're doing that. It's not helping. We're still getting bubbles in the reservoir, lots of them. And I mean LOTS. I talked to the folks at Medtronic and they gave me some suggestions that we weren't doing - degassing the vial, among other things - so we're going to try them. It's no longer only happening at night, because it happened again today at the daycare. I'm getting frustrated.

Also, make sure the insulin is warm (room-temp) when you're filling reservoirs - when it warms up, it can cause air bubbles

When I took apart the pump last night, there were bubbles not only in the tubing, but also in the cartridge--and I *know* there'd been no air in that cartridge the night before. It was full of small bubbles and that's what was getting into the air line. We do have cats but they can't get at the tubing - he wears pump-pocket shirts so the tubing is either under his clothes or sealed away in the pump pocket. Plus he doesn't like the cats and won't let them come near him.

My current theory is that there's some sort of issue in the interface between the cartridge and the pump itself that's allowing air to enter. I need to talk to the folks at Medtronic.

Hi !

Maybe your nighttime requirement are much different that your day requirement... They are for me... I have 0.1 units from 0:00 - 3:00, which is about 10% from my usual dose... Having high sugar in morning, doesn't neccessary mean that you had high sugar, but it can mean that you had very low sugar and your body reacted to it... Fine tuning night requirement can be a problem... As you can see I have very low setting on start of day, but even before that I don't cover whole BG/CH. From 22:00 - 23:59 I use just 75% of any normally calculated dose and after 0:00 only 50%... This works for me... Oh and after 3 AM, when dawn phenomen sets in I have about 1.8 U/h, so difference is quite big... on start of pump usage (about 6 months ago, I checked my BG every hour, so that I could set everything correctly...

if there's bubbles in the tubing, prime them out - whenever i notice that i'm running high, the first thing i check for is bubbles. if i find bubbles, i'll prime them out and be done with it - no need to stab myself with another site, or waste a battery or cartridge, if they're probably not going to help.
Also, do you have a cat or puppy? animals love to play with (read: bite or claw) the tubing, which can create make holes. Last idea i have is simply poorly adjusted nighttime basal rates

And I should add, it seems to be only happening at night. Daytime, no such troubles. Numbers during the day are GREAT, but nights are another story.

What can anyone tell me about bubbles in the infusion tubing? We're on a Medtronic Paradigm pump using Silhouette infusion sets. Three nights running, my son has had bubbles of anywhere from 1 mm to 1 cm in length, and his BG goes sky high as a result. Ketones, too. We've tried changing the site, the infusion set, the cartridge, even the battery (tonight, we did all of the above). His little bum just isn't up for daily site changes. Help!

I finally got plugged into my MM with insulin at lunchtime!! Thanks to this site, the nurse felt I had done lots of studying! Just had to do a Happy-Happy-Joy-Joy dance! =)

I also had a pump fail on me. I went to my Dr. office and the gave me a Lantus pen. It worked great for the 3 days I didn't have my pump ( also a UPS problem). I really did love sleeping with no pump attached to me though.

Geoffrey,
Yea, that was certainly an option but MM initially promised to get me a repl pump the next day - a Saturday. But UPS screwed up and failed to make the delivery. We left our vacation spot mid-day Monday, so we just rerouted the repl pump to be sent home by Tuesday. It was not worth it in my mind to go buy some Lente for 2 days.
