I always keep my current vial of insulin in my small kit, which I keep in my bag. I still somehow always end up with some air in the reservoir despite using room temp insulin. It usually appears after I've had a rservoir in the pump for a day or two. Someone once told me that the insulin will warm up a little more once the reservoir is put into the pump, and air bubbles can still form. They're rarely enough to cause a problem and they don't even seem to move once they form. I just check it a couple of times a day and if a bubble works its way to the top, near the tubing, I'll prime it out. I'm near the end of my current 300 unit reservoir and I have had a smallish-medium bubble in the reservoir for days now but it's just been hanging out, not floating to the top. I plan on putting a new one in tomorrow so I'm ignoring it.
