Temp basal limitations
Prohibited temp basals: You cannot set a temp basal of 0%, as there would be no
change from the Basal Program in progress.
Maximum temp basal:
• When using percent (%), you can set the temp basal up to 95% more than
your Basal Program in progress'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 at rate (U/hr), you cannot set a temp basal above your
Maximum Basal Rate.
Temp basals that turn o basal insulin delivery: When using percent (%), if
you set a decrease that results in a ow of less than 0.05 U/hr for a segment, the
Omnipod 5 app 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. is is
because the Pod delivers insulin in 0.05 U pulses.
For example, if the ow 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 ow 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 ow rate of 0.04 U/hr results in a delivery of 0 U
insulin in the rst hour and 0.05 U insulin in the second hour.
You can set a temp basal to turn o basal insulin delivery for a set period of time by
using a 100% decrease or a at rate of 0 U/hr. e 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 o basal insulin delivery.
Tip: Using a temp basal to turn o basal insulin delivery is useful if you want your
Basal Program to automatically start when the temp basal ends (see "Chapter 7:
Temporary Basal Rates and Presets" on page 81).
