Insulet Omnipod GO User Manual page 74

Protection from Over-infusion or Under-infusion
The Pod software monitors the infusion rate. If an error that would
result in over- or under-infusion is detected and cannot be corrected,
insulin delivery stops, an alarm sounds and the Pod light shows as
solid red. See "3.4. When the Pod has Stopped: Alarms" on page 48 for
more information about alarms.
Blockage (occlusion) detection
A blockage (occlusion) is an interruption in insulin delivery from the
Pod. A blockage may result from blocked tubing, Pod malfunction, or
from using old or inactive insulin. If the Omnipod GO Pod detects a
blockage, it sounds a hazard alarm and its Pod light turns red to tell
you to change your Pod.
A blockage (occlusion) hazard alarm sounds when an average of
3 units to 5 units of missed insulin occurs. The following table depicts
blockage detection for three different situations when using U-100
insulin. For example, if the Pod's cannula becomes blocked while
using a 25 U/day Pod, 5.5 hours may pass before the Pod sounds a
hazard alarm.
Basal
10 U/day
25 U/day
40 U/day
If a blockage spontaneously clears up, a volume of insulin could
be released. That volume would not exceed the volume of the
pre-programmed insulin intended for delivery.
