12 Understanding PDM and Pod Function
What the Pod can do between PDM instructions
Once activated, the Pod can perform the following without input from the PDM:
•
Deliver insulin according to the active Basal Program's schedule. The Pod
has a built-in clock that allows it to track the timing of the Basal Program's
segments.
•
Stop delivery of a temp basal at the scheduled time and resume delivery of the
active Basal Program.
•
Once a bolus or an extended bolus is started, complete the delivery of the
bolus.
•
Track the amount of insulin remaining inside the Pod.
•
Track the amount of time until Pod expiry. Stop delivering insulin once the
Pod expires.
•
Perform self-checks to verify that insulin delivery is occurring as expected.
Sound an alarm if it is not.
•
Send alarm and notification messages to the PDM, if it is in range.
•
Stop insulin delivery if the Auto-off feature is enabled and you have not used
the PDM within the specified period of time.
Auto-off
The optional Auto-off feature is useful if you are prone to hypoglycaemia
unawareness. When you enable the Auto-off feature, you define a length of time
for an Auto-off countdown timer. The Pod and PDM will sound an alarm if you
do not use your PDM within that amount of time. To change the Auto-off setting,
see "Pod Auto-off" on page 99.
Resetting the Auto-off countdown timer
Any action you take that causes the PDM to communicate with the Pod resets
the Auto-off countdown timer to the beginning. Therefore, if Auto-off is enabled,
make sure the PDM is in range of the Pod, then wake up your PDM. This resets
the timer and prevents the alarm from sounding.
Auto-off alarms
If you have not used your PDM within the amount of time specified by the Auto-
off countdown timer, the Pod and PDM sound an advisory alarm every minute
for 15 minutes. The PDM also displays an on-screen message.
If you do not use your PDM within 15 minutes of the onset of the Pod's Auto-off
advisory alarm, the Pod stops delivering insulin and both the PDM and Pod
sound a hazard alarm. Tap OK to silence the alarm and deactivate your Pod.
