do you ever find that there are a lot of bubbles sitting in it???? We're very diligent in getting all of the bubbles out of the resevoir and priming them out the tubing.. yet, everytime I'm doing a site change on DS, I seem to find that the resevoir is full of them!!! He's so sensitive to insulin, that this makes a huge difference if the air goes through to the tubing instead of insulin. I even took a picture if I'm not explaining it quite right... Am I doing something wrong when we first fill the resevoir? DOES it matter if the insulin is cold or room temp? We take it straight from the fridge, insert air into the vial, draw out insulin into the resevoir, take the vial off, attach the tubing, tap (whack) the vial until we see ALL VISIBLE bubbles rise to the top... visually inspect it to make sure there aren't any more hidden bubbles/air anywhere.. and push the plunger up while holding the tubing straight up.. and watch the air travel up out of the resevoir, into the tubing until we see some good drops of insulin coming out the end of the tubing (after we've seen the air bubbles go out first). Then.. it looks fine for a day or two, but then I notice bubbles starting to accumulate around day two and on day three of site change.. sometimes there are a lot. Anyone? Thanks!!!
