Insulin on Board (IOB)

In the settings we have activated the calculation for the Insulin on Board (IOB). The IOB value represents the number of insulin units that still have an effect on the blood glucose - even hours after the last injection. It is a rule of thumb based on the work of John Walsh (Author of Pumping Insulin). Please adjust the Duration of Insulin Activity (DIA) to your experiences. Walsh recommends to set the DIA between 240 to 360 minutes. More details in this discussion about the calculation of the IOB.
