CHAPTER 3
Understanding and Adjusting Basal Rates
What Is a Basal Rate?
A basal rate is a small base or background amount of insulin that 
is delivered, at a preset rate, continuously for a specified period of 
time.
Even without eating, our bodies need a small, constant supply 
of insulin for normal daily living. In people without diabetes, the 
pancreas continuously delivers this basal insulin. For people 
using the mylife OmniPod
®
 Insulin Management System, the 
Pod mimics a healthy pancreas by delivering insulin at the rate 
that you’ve programmed into the Personal Diabetes Manager 
(PDM).
Personalized Basal Programs
Insulin needs vary throughout the day. Therefore, most people 
set their basal rates to deliver slightly more or less insulin at 
certain times. For example, one person may need to deliver a 
higher rate of insulin during the early morning and a lower rate 
during the late evening. A basal program describes the amount 
of insulin to be delivered during an entire 24-hour period.
A basal program contains at least one basal rate for the 24-hour 
period, but for most people it will be broken into several time 
segments, or basal segments, each delivering a different rate of 
insulin. A sample basal program with three basal segments 
might be:
Approximately 50% of a person’s total daily insulin dose 
typically comes from basal insulin delivery; the remain-
ing 50% typically comes from bolus doses (see Chapter 4, 
Understanding and Delivering Bolus Doses).
00:00–08:00 
0.60 U/hr Between 00:00 (midnight) and 
08:00, the Pod delivers 0.60 
units of insulin per hour.
08:00–15:00
0.80 U/hr Between 08:00 and 15:00, the 
Pod delivers 0.80 units of insulin 
per hour.
15:00–24:00 
0.70 U/hr Between 15:00 and 24:00 
(midnight), the Pod delivers 
0.70 units of insulin per hour.
