  • Insulin pumps (technically called Continuous Subcutaneous Insulin Infusion, CSII) deliver insulin at programmed rates, from a pump worn externally through a small catheter tip inserted into the skin.
  • May be linked to a continuous glucose monitor (CGM), displaying real-time BG results, but insulin delivery is not driven by the blood glucose (BG) result; fully closed loop delivery system does not currently exist. Insulin delivery rates and amounts are determined by the patient.
  • However, some newer models include an insulin pump/CGM combo that provides a Threshold Suspend Feature, which suspends insulin delivery for up to 2 hours when the sensor glucose value reaches a preset low. This is a useful safety feature for patients with severe hypoglycemia unawareness.
  • CSII is an option for treating type 1 diabetes or unstable, insulin-requiring type 2 diabetes.
  • Only use rapid-acting (e.g. aspart, lispro or glulisine) or regular insulin (U-100 or U-500).
