Protection from Over-Infusion or Under-Infusion
e Pod soware monitors the infusion rate. If an error that would result in over-
infusion or under-infusion is detected and cannot be corrected, insulin delivery
stops, and an alarm sounds.
Blockage (occlusion) detection
Warning: ALWAYS monitor your glucose and follow your healthcare
provider's treatment guidelines when you stop receiving insulin due to a
blockage (occlusion). Not taking action promptly could result in under-
delivery of insulin which can lead to hyperglycemia or diabetic ketoacidosis
(DKA) (see" Blockage Detected" on page 163).
Caution: ALWAYS check your glucose frequently when you use very low
basal rates. Checking your glucose frequently can alert you to the presence of
a blockage (occlusion). Blockages can result in hyperglycemia.
A blockage (occlusion) is an interruption in insulin delivery from the Pod. If the
Omnipod 5 System detects a blockage, it sounds a hazard alarm and prompts you
to deactivate and change your Pod.
A blockage hazard alarm sounds when an average of 3 units to 5 units of missed
insulin occurs. e following table depicts blockage detection for three dierent
situations when using U-100 insulin. For example, if the Pod's cannula becomes
blocked when delivering a 5 U bolus, 35 minutes may pass before the Pod sounds
a hazard alarm.
Time between blockage and Pod alarm
Typical time Maximum time
5.00 U bolus 33 minutes 35 minutes
1.00 U/hr basal 3.0 hr 5.5hr
0.05 U/hr basal 51 hr 80 hr (Pod expiration)
If a blockage spontaneously clears up, a volume of insulin could be released. at
volume would not exceed the volume of the programmed insulin intended for
delivery.
If your Omnipod 5 System detects a potential blockage to your insulin delivery,
it will set a blockage alarm to sound. If a blockage alarm is set to alarm while an
immediate bolus is in progress, the alarm is delayed until completion of the bolus.
