example - bolus calculator (Pump_Extended)
Sample scenario
| Bolus delivery type | Bolus Activation type | Recommended total bolus |
Selected total bolus |
Confirmed total bolus | extended, /delayed bolus |
extended/ delayed duration |
immediate bolus |
BG/Carb used for Bolus calculation |
|---|---|---|---|---|---|---|---|---|
| PUMP_EXTENDED | Manually changed recommended bolus | 7 IU = (meal correction : 0 IU + BG correction : 7 IU) |
6 IU = (meal correction : 0 IU + BG correction : 6 IU) |
6 IU = (meal correction : 0 IU + BG correction : 6 IU) |
6 IU | 1200000 ms | - | BG - 170mg/dl Carb - 10g |
MedicationRequest resource containing primarily the Bolus calculation outcome (recommended, selected and confirmed boluses) and the details of the dose like delivery type = PUMP_EXTENDED, activation type = Manually changed recommended bolus.
MedicationAdministration resource containing the confirmed bolus and the details of the dose delivery type = PUMP_EXTENDED
