NOTES:
OTHER EDUCATION
Treat hypoglycemia with 5-10 g CHO since insulin
p
may have been reduced/suspended for a period of time
before hypoglycemia occurs.
Disconnecting: If disconnected for more than 20
p
minutes, SUSPEND insulin so Control-IQ calculates IOB
accurately
Infusion set failure: Change infusion set if unexplained
p
persistent hyperglycemia. ( i.e. >300 mg/dL for >90 min)

ADJUST
• Primary SAFETY Goal:
Insulin Reduce Hypoglycemia
(< 70 mg/dL) to < 4%
Dose
• Primary OVERALL Goal:
Increase Time-in-Range (70-
180 mg/dL) to >70%
• Change CORRECTION
FACTORS for hyper/hypo
that occurs 1-2 hours after
correction doses
• Change I:C RATIOS for
hyper/hypo 1-2 hours after
meal doses
• Change BASAL RATES

1-2 hours before hyper/
hypoglycemia by 10-25% (if
no preceding boluses)
