We have stated using the advance features and my son who is 15 is getting used to using EZ Carb and EZ BG. About 4 hours ago he was at 91 and about 2 hours ago he took 2.6 units to cover a snack. He just tested and was at 175 and ate 27 carbs at a 10:1 ratio. Normally we would give him insulin of 2.7 units and one for correction for a total of 3.7 units of insulin.
Using EZ BG it showed insulin on board and showed a insulin correction of only .35 units needed when factored with BG.
However , about 5 minutes later when I when I went back to check the number it showed no IOB and suggested the correction I would have given him (1 unit) without the meter suggestion.
Can't figure out why it changed so quickly in such a short time. Any ideas anyone. Should he be following the meter / pump IOB suggestions??
