12 Understanding PDM and Pod Function
When the Bolus Calculator does not work
e Bolus Calculator does not work when it is disabled or when it is set to o. You
control whether the Bolus Calculator is turned on or o, but the PDM controls
when it is disabled.
If the Bolus Calculator is set to o, the PDM does not track IOB and does not
suggest a bolus.
If the Bolus Calculator is set to on, the PDM may disable it in a few situations.
Being disabled means that the Bolus Calculator is temporarily unable to calculate
a suggested bolus.
Conditions that disable
