If the second blood glucose is above 250 mg/dL (13.9 mmol/L):
• Take an insulin injection by syringe (not through the pump). The amount should be the same as if you
were taking a correction bolus.
• Change the entire infusion set system (new reservoir, infusion set, and cannula). Consider changing the
insulin vial if you believe that the insulin is no longer stable.
• Check urine for ketones and call your healthcare professional if ketones are present.
• Drink liquid with no calories every 30 minutes (for example: 8 oz. diet ginger ale, broth, water).
• Test blood glucose every two hours and keep taking correction insulin until blood glucose reaches target.
• Call your healthcare professional if your blood glucose and urine ketones remain high or you are unable
to drink.
Treating hyperglycemia from illness or infection through insulin pump therapy will be discussed on the
following pages.
Diabetes ketoacidosis (DKA)
DKA results from untreated hyperglycemia. DKA is a serious medical problem that needs treatment right
away. The insulin pump therapy uses only fast-acting insulin, so DKA can occur rapidly if insulin delivery is
disrupted. It is important that you understand these guidelines.
Preventing DKA
If you have nausea or vomiting, immediately check your blood glucose and ketones. If your blood glucose is
above 250 mg/dL (13.9 mmol/L) and/or ketones are present:
• Take an injection of fast-acting or regular-acting insulin with a syringe (not through the pump). The
amount should be the same as if you were taking a correction bolus. If ketones are present, more insulin
may be needed. Contact your healthcare professional for guidelines for insulin doses especially when
ketones are present.
• Change the entire infusion set system (new reservoir, infusion set, and cannula). Consider changing the
insulin vial if you believe that the insulin is no longer stable.
• Call your healthcare professional.
• Troubleshoot the pump. If help is needed, please call our 24 Hour HelpLine for assistance.
• Drink liquids with no calories every 30 minutes (for example: 8 oz. diet ginger ale, broth, water).
• Check your blood glucose and ketones in one hour.
• Continue to take insulin as discussed with your healthcare professional.
• Call your healthcare professional right away if your blood glucose and ketones are not decreasing, or
you cannot drink fluids.
