Temp basal limitations
Prohibited temp basals: You cannot set a temp basal of 0%, as there would be no
change from the active Basal Program.
Maximum temp basal:
• When using per cent (%), you can set the temp basal up to 95% more than
your active Basal Program's rate with the following exception: You cannot set
a temp basal that would go above your Maximum Basal Rate during any time
segment covered by the temp basal duration.
• When using a flat rate (U/hr), you cannot set a temp basal above your
Maximum Basal Rate.
Temp basals that turn off basal insulin delivery: When using per cent (%), if you
set a decrease that results in a flow of less than 0.05 U/hr for a segment, the PDM
informs you that you will receive 0 U/hr of insulin for one or more segments.
If the temp basal is long enough, you will eventually receive some insulin. This is
because the Pod delivers insulin in 0.05 U pulses. For example, if the flow rate for a
basal segment is 0.10 U/hr and you create a temp basal with a 60% decrease for:
• One hour, the resulting flow rate of 0.04 U/hr results in no insulin being
delivered for the one hour duration of the temp basal.
• Two hours, the resulting flow rate of 0.04 U/hr results in a delivery of 0 U
insulin in the first hour and 0.05 U insulin in the second hour.
Tip: Using a temp basal to turn off basal insulin delivery is useful if you want your
Basal Program to automatically resume when the temp basal ends (see "Methods to
temporarily stop insulin delivery" on page 142).
Temp basal presets
Some temporary changes in your daily routine are easy to predict, and you may
know from experience how they affect your insulin needs. For example, you
might join a summer football league or attend an exercise class. For women, your
monthly hormonal change can affect blood glucose in a predictable manner.
To handle predictable, short-term changes, you can define temp basal presets (see
"Temp basal presets" on page 79). Once stored, a temp basal preset can be activated
quickly at a later time (see "Activate a temp basal preset" on page 71).
