12 Understanding PDM and Pod Function
When you are not actively using the PDM, store it in a nearby location, such as a
shirt pocket or in a drawer, briefcase or handbag.
Status checks: How the PDM checks Pod function
The PDM periodically queries the Pod about its status, called a 'status check'. The
PDM performs a status check:
•
When you wake up the PDM.
•
When you navigate to the Pod Info tab.
•
Periodically, whether the PDM is awake or asleep. These 'sleeping status
checks' occur every five minutes.
Note: Following a sleeping status check, the PDM only wakes up and sounds
an audible alarm if the Pod has a hazard alarm. If the Pod has an advisory
alarm or a notification, the PDM remains asleep and silent.
During a status check, the PDM collects information from the Pod about bolus
deliveries, the amount of remaining insulin and any alarm situations. The PDM
displays this information as follows:
•
The Home screen displays information about the most recent bolus.
•
The Pod icon on the status bar shows how much insulin remains in the Pod's
reservoir (see "The Status Bar" on page 9).
•
The Lock screen and a full screen message display information about Pod
alarms.
Timing of alarms originating in the Pod
If the Pod is sounding a hazard alarm, the Pod broadcasts a signal to the PDM.
•
If the PDM is in range and awake, within 25 seconds of the Pod's initial alarm
sound, the PDM also sounds an alarm and displays the alarm message.
•
If the PDM is in range but asleep, the Pod cannot wake it up. The PDM finds
out about the Pod alarm when it does a 'sleeping status check'. In this case,
there could be a delay of up to five minutes and 25 seconds between when the
Pod sounds the alarm and when the PDM sounds the alarm.
•
If the PDM is out of range of the Pod, the PDM cannot receive any
communication from the Pod. Therefore, if you hear a Pod alarm or
notification, bring the PDM in range of the Pod and wake the PDM up.
Within 25 seconds, the PDM sounds the alarm and displays the alarm
message.
