Dose adjustment when using an insulin pump:
Our goal is to help you learn to make
rate and ratio adjustments independently
Insulin
requirements regularly change. To achieve a target HbA1c (measure of
complications risk) it is important to change pump settings when BGLs show a
pattern outside the target range. If you have made setting changes and your
BGLs are still outside target range, you can phone or email the DNE team during
office hours for advice
YOUR BGL TARGET
is 4.0 mmol/L- 7.0mmol/L.
YOUR HbA1c
TARGET is less than 53 mmol/mol (less than 7.0%)

Pump terms reference guide:
Bolus Insulin:
Carbohydrate
Bolus; insulin to carbohydrate ratio (ICR):
Insulin delivered following entry of
carbohydrate to be consumed
Correction
Bolus; Insulin sensitivity factor (ISF)/ Correction Factor (CF ):
Insulin delivered to correct an above pump
target BGL
Basal insulin:
Background insulin delivered continuously
Review of your pump upload:
- Look
on the download for patterns in your BGL over a minimum of 3 days (except on
sick days). Do not adjust settings based
on only one or two readings.
- BGLs
out of target range 3 days in a row or 4 times in one week at the same time of day indicate that a change should be
considered.
- Wait
3 days to assess the effect of any adjustment before making another change
- Aim
for no more than 5 different basal rate settings
- Aim
for no more than 3 different Insulin to ICR and ISF/CF
Hyperglycaemia (High blood glucose levels)
Should
you adjust the basal rate or bolus insulin?
- If
BGLs are elevated overnight or more than 4 hours after food, the basal rate is
likely to need changing. Consider increasing the basal rate by 10%, starting at
least 2 hours before the rise.
- If
BGLs are high 3 hours after a meal bolus, the ICR is likely to need a change.
Consider lowering the ICR ratio by 5%-10%. (E.g. Change 10 grams/unit to 9 or
9.5 grams/unit).
- If
BGLs are high 3 hrs after correction (and no food bolus has been given) the
ISF/CF is likely to need changing. Consider lowering the ISF/CF by 5%-10%.
Hypoglycaemia (Low blood glucose levels)
Should
you adjust the basal rate or bolus insulin?
- If
BGLs are low overnight or more than 4 hours after food, the basal rate is
likely to need changing. Consider reducing the basal rate by 10% starting at
least 2 hours before the rise. (E.g. 0.5 unit/hr to 0.45 units /hr)
- If
BGLs are low 3 hours after a meal bolus, the ICR is likely to need changing.
Consider increasing the ICR ratio by 5%-10%.
- If
BGLs are low 3 hrs after correction (and no food bolus has been given) the
ISF/CF is likely to need changing. Consider increasing the ISF/CF by 5%-10%.
