Page "Intensive insulinotherapy" Paragraph 9

An insulin pump can be programmed to infuse a steady amount of rapid-acting insulin under the skin.

This steady infusion is termed the basal rate and is designed to supply the background insulin needs.

Each time the patient eats, he or she must press a button on the pump to deliver a specified dose of insulin to cover that meal.

Extra insulin is also given the same way to correct a high glucose reading.

Although current pumps can include a glucose sensor, and they cannot automatically respond to meals or to rising or falling glucose levels.
