Educational Pearls:

• Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals
• Some connect to a continuous glucometer but often blood glucose needs to be checked manually
• Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor
• Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin
• The pump can be used to give a bolus of insulin in the emergency department if necessary
• Stopping the device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible
