Pump-Ins Action & BG

Before making any changes to insulin doses, it is important to understand the action of insulin (the onset, peak and duration of different types of insulin). Therefore, as background for the information that follows, we recommend you first review The Basics/Insulin Types & Action.

How Insulin Action Impacts Blood Glucose

Insulin is one of several factors that contributes to a given blood glucose reading at a certain moment in time. How insulin impacts blood glucose depends on the insulin action pattern of one of the three commonly used insulin programs:

1.  Conventional Insulin program

2.  Basal/Bolus Program with Multiple Daily Injections
3.  Insulin Pump Program

Remember, in the following text:

“rapid-acting” insulin refers to Humalog®, NovoRapid®, or Apidra®

Insulin Pump Program
[Continuous Subcutaneous Insulin Infusion (CSII) of Rapid-Acting Insulin only]

 Insulin Pump Insulin Action Graph

The insulin action diagram for a Pump program (above) shows that the blood glucose at a given time is affected by a certain previous insulin dose (follow the curve back) as follows:

Blood glucose before breakfast  tells you about  Overnight basal rates 
Blood glucose before lunch   tells you about
Morning basal rates + breakfast bolus
Blood glucose before supper   tells you about  Afternoon basal rates + lunch bolus 
Blood glucose at bedtime  tells you about  Evening basal rates + supper bolus  

For example, if the breakfast blood glucose is consistently out-of-range (high or low), you may want to change the overnight basal rates; if the supper blood glucose is consistently out-of-range (high or low) you may want to change the dose of lunch rapid-acting insulin and/or the afternoon basal rates.
