Understanding PDM and Pod Function 12
Basal Programs
A basal rate is the number of units of insulin delivered per hour.
A basal segment defines the time of day during which a given basal rate is
delivered.
A collection of basal segments covering a midnight-to-midnight period is called
a "Basal Program".In other words, a Basal Program describes the rate of insulin
delivery throughout an entire 24-hour period.

Insulin needs vary throughout the day. Therefore, most people set their basal
rates to deliver more or less insulin at certain times of day. For example, you could
deliver a lower rate of insulin during the night and a higher rate during the day.
This figure shows a Basal Program with three basal segments.
To create the Basal Program shown in the preceding figure, the following basal
segments are programmed into the PDM:
Segment
1: Midnight–10:00
2: 10:00 –14:00
3: 14:00 – midnight

Basal rate
0.20 U/hr
Between midnight and 10:00, the Pod
delivers 0.20 units of insulin per hour.
0.60 U/hr
Between 10:00 and 14:00, the Pod delivers
0.60 units of insulin per hour.
0.30 U/hr
Between 14:00 and midnight, the Pod
delivers 0.30 units of insulin per hour.
