23Understanding Insulin Delivery and Calculations
23.1. Basal Insulin Delivery
Even without eating, our bodies need a small, constant supply of insulin for
normal daily living, which is referred to as "basal" insulin. In people without
diabetes, the pancreas continuously delivers this basal insulin. For people using
the Omnipod 5 System, the Pod can mimic a healthy pancreas by delivering basal
insulin continuously as your wear the Pod.
About half of a person’s total daily insulin (TDI) dose typically comes from basal
insulin delivery; the other half typically comes from bolus doses.
In the Omnipod 5 System, basal delivery occurs dierently depending on which
of the two modes you are operating in: Manual or Automated.
Manual Mode Basal Programs
A basal rate is the number of units of insulin delivered per hour.
A basal segment denes 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. erefore, 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.
