At what temperature or for what length exposure of insulin do you use Frio or other insulin cooling system? We were living through a hot Southern summer when my daughter was dx-ed and during her 6 months on MDI, and during that period we always brought freezer packs with us to keep the insulin cool. But ever since starting the pump and moving to Colorado (which has temperate summers), we haven't sweated insulin temperature very often. We're going on a couple of 2-night car camping trips this summer, where the backup insulin will be outside for 48 hours at temps topping out around 85 for a few hours late in the day. We'll probably throw the insulin in the drink cooler, but I'm curious if there is a rule of thumb / cutoff for when to do this? And if the insulin in the bottle is at risk, would the insulin in her pod reservoir be also?
