Midnight–7:00 am 0.20

0.20 x 50%=0.10 0.20 + 0.10 = 0.30
10:00 am–2:00 pm 0.60 0.60 x 50%=0.30 0.60 + 0.30 = 0.90
2:00 pm–4:30 pm 0.30 0.30 x 50%=0.15 0.30 + 0.15 = 0.45
4:30 pm–midnight 0.30
* Time segments are defined by the currently scheduled Basal Program.
Temp basal limitations
Prohibited temp basals (%) : When using percent (%), you cannot set a temp
basal that results in a flow of less than 0.05 U/hr. For example, if the flow rate for a
basal segment is 0.10 U/hr, then you cannot create a temp basal of 60% less as that
would result in a flow of 0.04 U/hr.
Also, you cannot set a temp basal of 0%, as there would be no change from the
active Basal Program.
Maximum temp basal (%): When using percent (%), 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.
Maximum temp basal (U/hr)
: When using a flat rate (U/hr), you cannot set a
temp basal above your Maximum Basal Rate.
Using temp basals to turn off basal insulin delivery:
You can set a temp basal to
turn off basal insulin delivery for a set period of time. This occurs if you decrease
the temp basal amount until the screen reads "Off." The Pod beeps at the start and
end of a temp basal period of no basal insulin. You can still deliver boluses when
using a temp basal to turn off basal insulin delivery.
Tip: Turning off basal insulin delivery in this way, rather than using the
Suspend and Resume feature, 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 soccer league or occasionally attend an exercise class. For
women, your monthly hormonal change can affect blood glucose in a predictable
manner.
