Insulin pumps in children - a systematic review

Figure 3 Basal and bolus insulin. Basal insulin is delivered continuously in a small amount as a background to keep the blood glucose levels within the target between meals. The pump can be programmed to deliver at different rates within 24 h. Bolus insulin is a large amount delivered over a short period, which can be given at any time. The pre-meal bolus is given based on the number of carbohydrates in grams. The bolus can also be given to correct high blood glucose levels.
