i've been pumping for about 2 months now and i've been so frustrated when changing out my cartridge because no matter how hard i try to prime and keep as close to 200 units in my cartridge after my prime has been impossible.
then i realized (assuming anyway) that i have not been taking into account for the insulin inside the tubing from doing the actual prime. Is this accurate in that the tubing might hold about 15 units of insulin ?? My cartridge holds 200 units and i always end up averaging 185-187 units after prime.
Thanks to anybody looking at this.
