Does anyone know what HI means on a freestyle lite? I have been up all night....3 site changes, tubing change, insulin change....and HI readings all night. He is finally down to 210! He was outside all day and so was the pollen...poor guy has terrible allergies. So, I think he is either getting sick or his numbers are showing allergies. So, I can't find my freestyle book or located it on the internet, I figure you guys will be much quicker!
