I'll give you the cliff's notes questions, then follow with the story for context:
1. What could cause air to get into my pump tube? It's been fine for like a day and a half, but it had air in it this morning (probably before I woke up). I can't think of much that was different, except maybe that my tube was stretched a little bit more than usual while I slept... But not like, STRETCHED stretched.
2. If you prime air out of your tube, should you assume there's still insulin in the canulla and not "fill canulla?"
3. I'm not at dangerous numbers this time around (thanks to still being in my "honeymoon," I assume), but let's say I ate breakfast then wound up with a BG of like 300+. In a situation like that, should I correct with the assumption that I'd gotten no insulin at all with my meal?
OK, so here's the context:
So I woke up w/ a BG around 160... that's higher than my usual fasting number by about 50 points. But I was going to take a short run/walk before breakfast, so I didn't correct... then it was still at about the same before breakfast, so I followed my pump's (Animas Ping's) recommendations to bolus for both food and BG correction... Got to work and Dexom showed my numbers around 250! I started checking my pump and discovered air in the tube, which I primed out... though I didn't really "fill cannula" since I thought, you know, there could still be insulin in the canulla. (I tricked it by "filling" it when it wasn't connected.)
So I get out my meter remote to test and correct... but, what? 153? So I calibrated my Dexcom (it's been less than 12 hours since putting in the new sensor, so I can't get too mad at the discrepency) and decided that, though I'd normally be lower than this 1.5 hours after a bolus that included a correction (especially since it was a fairly low-carb breakfast), I clearly may have gotten some insulin at breakfast and need to wait to correct.
